Who is this article useful for?

• Dear friends who have questions to buy chargers of all types: Laptop - Notebook - Ultrabook - Surface - Apple MacBook.
• People who want to buy laptop and notebook chargers Types: Asus laptops - Dell notebooks - Acer laptops and notebooks - Fujitsu - Samsung - Sony and other brands in the market.
• Those who are looking to buy Type C chargers and "USB laptop chargers".
• People who are confused about searching and buying a gaming laptop charger or can not find the charger they need.
• Users who have questions about buying an industrial laptop charger.

Application of power supply for laptop

Laptop; Like any computer you know, it needs electrical power supplied by an power adapter. AC ADAPTER or "charger" are both suitable for "portable" computer power supply because in addition to supplying voltage to the circuit and components, it is also responsible for charging the battery. Without a power supply, even the most powerful computers, such as gaming laptops and industrial laptops, lose their function. Laptop power supply is designed and made portable "PORTABLE". Laptop adapters and chargers receive high voltage (V) above the city power supply, reduce it, and adjust the amp (A) and sometimes increase it. This process causes that; The output power (WATT) of the adapter is in line with the needs of the device and makes it usable for one or more laptop models.

• Depending on the needs and processing power of each laptop, a special adapter is provided for it.
• The most important functional components of the charger include: voltage - amps - watts - mains connector and its form factor.
• The laptop charger receives the high voltage and reduces it and uses it with a higher amp ready.
• Chargers have different sockets, and in circular models, polarity is important.
• The weight or appearance of the adapter does not matter if it is genuine or counterfeit and cannot be cited.
• There are chargers with Universal platform, which do not cause any problems if they are used intermittently.
• The biggest enemy of chargers: shock - humidity - high heat and powerful electric shocks.

One reason to disconnect the charger is to prevent the transfer of noise and heat from the adapter to the device. This makes laptops thinner and the charger easier to replace. 

Power adapter - "Portable" laptop charger has two main and important functions:

1. Sends the power required to turn on a laptop - notebook or any laptop = Receive 220 volts of Iranian electricity and convert it to the exact needs of the device
2. Power supply to charge the battery: Lithium ion (portable battery) or lithium ion polymer (internal battery) while keeping the device on

Laptop charger function

Newer models of these adapters operate beyond the switching source. It is a bit difficult (extensive) to study and introduce this type of nutrition source electronically. But in general, these adapters usually increase the input amp by about 5 times while reducing the input voltage by approximately one tenth. This current then enters the laptop's electronic circuit via the charger output cable and via DC JACK. Meanwhile, signals are always being exchanged between the computer and the power supply.

AC ADAPTER

AC Adapter (AC) is an adapter that reverses the direction of electrical current intermittently and periodically.

Application of AC VOLTAGE

Almost all homes and offices use AC outlets because it is relatively easy to generate and send AC power over long distances.

DC ADAPTER

Is an adapter whose electric current is only in one direction (direct current)

Application of DC VOLTAGE

All electrical appliances work with DC, or anything that works with a battery, or plugs into a wall with a DC adapter, or uses a USB cable. DC-based electrical appliances such as cell phones or flashlights or flat-screen TVs.

Adapter connection to the system

The process of powering the components of the laptop and the energy required to charge the battery of this device is always under control. This information is constantly reviewed and updated, and signals (between: adapter - battery - computer circuit) are being reviewed and exchanged. Effective communication between the adapter and the system is done with the help of IO and Q series controllers. Of course, the issue of troubleshooting the adapter and power supply problems does not fit into this topic. Here we review the adapters in general and introduce its types to you.

Types of charges from the past to the present

The first adapters in all-inclusive laptop generations had an output of 18.5 .5 19.5 volts and 5 to 10 amps of power. This is relative to the component configuration. Laptops with a powerful CPU and GPU used a variety of adapters with higher electronic power.

New chargers

Due to the advancement of nanotechnology and the optimization of the processing process of computer systems, their electrical power supply has also undergone optimal changes. Newer laptops and notebooks have optimized operating frequencies that reduce power consumption. As a result, the amount of voltage and amps (power) they need is reduced. For today's notebooks and ultrabooks, in newer versions, fast charging technology and simpler and more efficient sockets have undergone major changes to the adapter structure.

One charger for all laptops

Universal adapters are a generation of laptop power outages. They are designed to provide the electrical power required by most laptop models. These adapters are approximately synchronized with the voltage required by the device. Along with the versatile charger, there are a number of different connectors, the end of which supports a 5.5 x 2.5 mm socket input of a multifunctional adapter. Some of these sockets include the following:

1. 5.5 * 2.5 to 7.4 * 5.0 mm socket is used to charge some DELL and HP laptops.
2. Converter 5.5 x 2.5 to 4.5 x 3.0 mm, which is used to charge HP laptops.
3. Convert socket 5.5 x 2.5 mm to 6.5 x 4.4 mm, which is used to charge Sony laptops.
4. 5.5 x 2.5 mm converter to 5.0 x 3.0 mm connector that can charge most Samsung laptop models.

What is the reason for replacing or buying a charger ?!

Failure of the charger completely or disconnection of the output wire is one of the most common reasons for buying this product. Direct connection of the power supply to the "high power" city power supply usually makes the adapter and charger vulnerable. These are the reasons why the user gets involved in fixing the laptop charging problem. However, in some cases, the primary charger may be intact and the user may need a secondary power supply. In these cases it is necessary to use a charging adapter compatible with the device. However: If you are planning to buy and replace it, it is better to read this article before taking any action.

Important point for choosing and buying a notebook or laptop charger

1. One of the things that makes the similarity or difference between different types of charging adapters is their "socket". It is very important that the "fabric charger" connector is the same as the "replacement charger".
2. The socket heads of some chargers are very similar in appearance to the charging jack of your laptop. But the same and the perfect match of the socket and connector is the most important criterion for choosing a charger.
3. The most important thing to consider when buying: Pay attention to the "watt output of the charger". Output watt: is the product of voltage (V and amp output of charger A).
4. Carelessness and disregard for important features of the charger, such as the type and amount of power output, as well as not paying attention to the needs (voltage and amps received) of the laptop can damage your device.

1- Check and match the connector and socket

Check: Does the adapter you choose match your charger in terms of connector? Laptop Charger Connectors Except for some special cases, they are usually round and cylindrical, many of these connectors are similar in appearance but it is good to know: the small parts of the connector or socket may be different. The round connector is divided into two models: with a middle hole and with a middle needle.

Application of adapter socket and charger

The laptop charger uses a variety of voltage sockets to connect to the device. There are different types of these sockets. In terms of shape, they include: round and circular types, rectangular and rectangular models and other models. To identify circular models, you can accurately measure the inside and outside diameters of the socket. The most famous circular connector: 2.5 mm inner diameter and 5 mm outer diameter. There may be differences and similarities in such models. . Some circular connectors contain an internal needle. But in some models, this needle is embedded inside the DC JACK. The highest variety of connectors has been observed among Asus products.

Special and new connectors

For some laptops, special connectors are provided. For example, some Lenovo devices use dedicated Yoga and USB connectors. One of the connectors used for all types of mobile phones and tablets is the Micro USB model. Of course, this model is also used to connect the charger to some laptops. Most electronic devices today use the U.S.B TYPE C port. With the invention of the power supply based on fast charge technology and according to their structural needs, the technology of the third generation USB port has also been expanded.

Voltage and amps mean life or death of electronic devices

As I said before, the important thing to pay attention to is the voltage and amp of the adapter. The output power of the replacement adapter must be the same as the previous charger of the device. Even if the head of your laptop charger connector is the same as the other adapter, do not connect the adapter before making sure that the amp and voltage are the same! More powerful laptops and devices with secondary graphics require more electrical energy. This energy is supplied through voltage + amperes (power). New and more powerful gaming laptops use two power supplies at the same time.

• The duration and extent of the damage may vary depending on the amount of high voltage.
• Sometimes the device does not turn on and in some cases your laptop will be damaged after a while.

for example :

If the laptop needs: "19V 4.7" adapter, you can use "19V 6.3" amps instead, but you can not use the 19V 3.42A adapter (less amps) Because it causes damage to the laptop battery in a short period of time. In many cases, the laptop may not turn on. It is better not to use an adapter with "output amp" lower than the laptop needs.

Briefly

Voltage (V) means the amount of electricity, for example: 19 volts or 19.54 volts, and ampere (A) means its current intensity, for example: 5 amps. The adapter that connects to your laptop should not supply a voltage higher than what is intended for the laptop circuit. If you have an improper adapter connected to the device, the speed and type of damage will vary depending on the amount of voltage that is exceeded. If the voltage (V) of the charger is higher than the laptop needs, the device heats up quickly and the smell of burns rises from its board.

The following rule should be considered when deciding to buy a new adapter!

Conditions for replacing a laptop charger adapter are such that the watt output of the adapter should be the same as your device needs. When preparing a new adapter, you can use an adapter with a (slightly) higher output amp. Of course, if (adapter connection) does not cause problems for the laptop by causing problems such as: hanging, jumping touchpad or mouse.

What difference does the size of the laptop adapter make?

You may be wondering why some types of adapters and chargers are smaller in size? And do large adapters work better than small chargers !? In answer to this question, I must say: In general, the criterion of the size of the adapter has nothing to do with its quality, but depends on its output watt. Laptops vary depending on the design and needs of their hardware components. Affects the size of the adapter. Laptops with more powerful processors usually consume more power. Devices with secondary graphics also require a higher percentage of energy to operate the graphics equipment.

The reason why some chargers are small is because either a larger charger is not needed or it is basically designed for a laptop or notebook (small and light), most of the charger space is occupied by the transformer inside. Of course, do not hesitate to buy small and light adapters that are different from the standard model (manufacturer).

Product quality and warranty

Counterfeit products are sometimes similar in weight to the original adapters. The original adapters are heavier in weight. This happens naturally because original adapters have many components, each with its own value; But the copy adapters are lighter in weight and use more metal inside to bring the weight of the counterfeit product closer to the weight of the original product. When buying a laptop charger, make sure that the product is original.

About the quality of construction and parts (adapter and charger)

The original and original adapters are exactly the same in appearance in many cases as the fake adapters. Production of adapter frame does not require special technology and design; But most of the original adapters "brand of laptop and charger manufacturer" are engraved on the frame. Of course, this also applies to copy adapters. As a result, the apparent similarity of "replacement charger" with "fabric charger" is not considered as a criterion (originality or originality) of the product.

Disadvantages of non-original and substandard adapters!

• Generating relatively high heat in these adapters, which indicates an improper design.
• Protective faults in non-original adapter circuit
• The main board is a single-layer or single-sided board that practically cannot run advanced circuits at a low level.
• Weakness or absence of filtering circuit to prevent adapter noise on other parts of the circuit.
• In many cases the solder quality is poor and even manual.
• Lack of metal layer on the adapter whose job is to collect static electricity and transfer it to earth.

How do you feel about buying a charger?

What can make you think about the quality of the product when buying a laptop charger adapter: warranty and guarantee. By purchasing a laptop charger adapter with a valid warranty and guarantee, you will ensure that: The quality and long-term durability of the product will be reliable and predictable. Be sure (even if the product does not have an official warranty card) it guarantees it itself. A seller who is confident in the quality of his product will use his credit to make you buy with confidence.

All kinds of warranty and guarantee for laptop and notebook adapters and chargers:

• The warranty period is considered from the beginning of the consumption period until the specified period after that.
• The warranty may include replacement or repair of the charger.
• Usually physical injuries are not covered by the warranty.
• Products guaranteed by the seller of the goods are more reliable.
• Warranties are applicable in several cases, even for similar goods.
• The initial warranty can be made by the importer or special services and warranty companies.
• Product specifications and warranty information are specified by barcode, warranty label or warranty card.
• Some of these warranties can be inquired through the support site of the product warranty company.

Some other guarantees are applied by the seller of the goods:

• Such guarantees are provided orally or in writing.
• The guarantee contract can be included in the goods invoice.

Of course, there are conditions for guaranteeing and guaranteeing the goods!

Electronic goods have a certain useful life, and breaking the laptop charger on the first day of use is unreasonable, but if the charger breaks down quickly due to improper use or physical damage to the product, the warranty will be void. The following items are out of warranty:

• Cut or tear the adapter cable wire
• Peeling the connector or breaking the middle of the connector
• Injuries due to severe power fluctuations
• Things like waterlogging or exposure of the adapter to liquids
• Use the adapter in hazardous places such as industrial workshops
• Fracture of the frame and body due to impact, which may lead to breakage of the adapter
• Impact due to the adapter falling through the charger and hitting hard surfaces
• And other defects that cause your adapter to expire suddenly

The easiest way to understand the model of adapter and charger of laptop or notebook

I have already spoken in the article introducing part number ( Laptop parts ) as a criterion for measuring and matching the product. Part number is the best way to understand the laptop charger model. According to the International Commodity Code (Part Number), you can find the type of part you want and replace the part you want, without the need for any other information. Knowing part number has other benefits as well. I invite you to read the full article about part numbers.

• The manufacturer usually has an adapter model for use on several laptop models
• The best solution for buying a charger is to pay attention to the part number of the product.
• The part number of the product produced by each company is considered exclusive.
• Adapters may be custom-made by a specific region or company.
• Many similar products differ in terms of part number.

Your laptop makes your business information, hobbies and important files portable and convenient

You can take your laptop with you wherever you go, whether you work at home, or go to a coffee shop or park for fun. However, one of the most important accessories you can have is a laptop adapter ( Charger) or the power cord of the device.

If the battery runs out, your computer needs power to keep working. A missing or damaged adapter can seriously slow you down. Even if you have not lost your laptop adapter, you may want to get a backup charger to keep at home or at work. Here are some steps to help you quickly find the right adapter for your laptop so you can work and play again safely.

Conclusion

Understanding the exact model of the charger adapter is sometimes a hassle. It's not an interesting idea at all that my laptop model is Toshiba, but my friend Acer laptop charger, which can be replaced (because of the similarity of appearance) for my device. Unless the technical specifications of these two power supplies are exactly the same. You should never judge by appearance and buy a charger. You can find out the real model of your adapter from the part number. Here is another important point. That many factories produce charging models that have different qualities. Finally, I have listed the most important points for buying the right charger for you.

• The voltage and amps and finally the output wattage should be the same.
• In some cases there is no problem with very small differences in voltage and amps.
• Excessive difference in the output current of the charger at the moment of connection is harmful.
• If the input current is more or less than your device needs, it will damage over time.
• The issue of uniformity and perfect fit: The form of the charging socket with your laptop is very important.
• Polarity problem: The same positive and negative currents are of special importance.
• You can find out the model according to the part number written (on the body of the adapter).
• Some counterfeit adapters are identical in appearance to the original.
• The warranty or guarantee of the charger can also indicate the quality of the product.

What is the difference between a charger and an adapter?

A charger is an electronic device used to charge a device (such as a battery or a capacitor). While the adapter (specifically) is used to provide the required voltage to the power supply of electronic devices such as laptops or fans. Although some adapters and chargers are identical in appearance, the main difference between the two devices depends on the type of application. The power adapter in notebooks is known as a laptop charger. If you want to know the difference between an power adapter and a charger, join us.

The difference between a charger and an adapter in terms of functionality

If you remove your laptop battery and the adapter is connected and you try to turn on the laptop, then it will turn on. Because the adapter is designed to provide the required voltage to the laptop (to operate without battery). It is interesting to know that when you connect the adapter, the current does not connect directly to the battery. There is actually an extra circuit inside the laptop that charges the battery from the electrical current of the adapter.

In this case, let's look at mobile. Your mobile phone will not turn on without the battery. Even if the charger is connected to the device. Because the mobile phone charger is only used to charge the mobile battery. Also, the mobile phone receives its voltage only from the battery. Whether the charger is connected to the device or not.

General definition of charger (DC)

A charger is a device that transmits electrical energy to a rechargeable battery. In fact, a charger is used to regulate the flow of electricity. One of the uses of the charger is to convert AC voltage to low DC voltage. Have you ever seen and worked with different types of chargers? They can be used to charge your mobile phone, wireless headphones, Bluetooth speakers or any other device.

A practical example of charging:

Suppose we have a 4.2V, 3000 mAh battery. Now we want to charge it. Electricity in Iran is 220 volts AC. Or, for example, we have 230 volts AC (India) or 120 volts ampere (USA). In this case, a charger is required to convert 220V AC to 5V DC. This means that it can reduce the voltage to the required amount of the mobile battery and convert its current from AC to DC. The mobile charger charges the battery but does not charge the phone without the battery. This is the difference between your mobile charger and your laptop adapter.

Therefore, the charger is only designed to charge the battery.

General definition of adapter (AC)

If you want to know the difference between a charger and an adapter, I have to say: A power adapter is a portable electronic device that looks and feels like a charger. According to Tricky Tech (adapters), it is also a device for converting power. But using an adapter is different from charging. This means that the adapter output is not limited to DC. The adapter can produce both AC and Dc outputs. This is considered to be the most important difference between a charger and an adapter.

Adapters in: computers, game consoles, monitors, speakers and…. Used. The general public believes that a laptop adapter is the same as a charger. Of course, all these people are wrong. Because of the difference

A practical example of an adapter:

Suppose we have a 5 volt DC fan. If we want to use this 5 volts, we need 5 volts current. An adapter is required here. Therefore, the adapter is designed only to supply the required voltage to the fan. If the fan has 5 volts AC. We need an adapter that can provide 5 volts AC as the output. 

"When we connect the adapter, it accepts the laptop's power supply, and at the same time as the device is powered, the battery is charged. When we disconnect the adapter from the device, then the laptop takes the required voltage from the battery and "It continues to work. But chargers do not have this feature, and that is the most important difference between a charger and an adapter."

Universal Charger | What we need to know

Fortunately, with the presence of universal chargers, you can charge any different device. Basically, the amount of voltage and amps in these adapters can be changed. The great thing about the power adapter is that the device only gets as much power as it needs. These power supplies are capable of generating a variety of voltages and use the internal resistance of systems to calculate current flow. In this article, we are going to introduce you to 3 models of the best universal charger.

Belker 90W Slim Universal AC Laptop Charger

In recent years, Belker has decided to produce a versatile adapter that can be used to charge any type of laptop. Due to his special expertise in the production of power supplies, he was able to design a Universal adapter whose amps and voltages were tailored to the needs of the device. Even these adapters can be used for TVs, printers and the like.

Input Power

The Belker 90W Slim Universal AC Laptop Charger has an advanced transformer capable of receiving input power from 100 to 240 volts. This means that if you go on a trip, you can charge all your electrical devices with just one adapter. It can also be used anywhere in the world with its plug (it needs a conversion in Iran).

Electrical output

When it comes to output power, it is not easy to create voltage at different levels. Devices that can do this have high costs and are called laboratory power supplies. Belker surpassed these power supplies and created a circuit that could generate different voltages. This charger supports 15 volts, 16 volts, 18.5 volts, 19 volts and 20 volts. It can produce up to 90 watts. Unlike voltage, power consumption is a good curve. If you wish, you can use a 40 watt charger, a 20 watt charger or even a 87.235 watt charger. You can work well as long as it is below 90 watts.

Connectivity

In order to be able to connect to all devices, this charger has 18 different connectors. Through the label on each connector, you can find out which connector should be used for each laptop. 90% of users do not have a problem choosing the desired connector for their device. But it is important to remember that these cables are not completely limited to one type of input socket. If you do not find your computer brand in the list, do not worry. If the dimensions of the connector are the same as your charger jack, you can use an adapter.

Designing:

One of the outstanding features of this charger is its compactness and it fits easily in a bag. This charger has a long wire 6 feet long.

LVSun 90W Universal Laptop Charger

LVSun is a very large importer of electronics. In fact, it has the same brand new charger and is sold in stores at twice the price.

Input Power

The LVSun 90W Universal Charger is designed for the US market, so it only accepts 100 to 120 volts input. This voltage range is slightly higher than normal. So you can use it for any type of laptop. This may not be suitable for travel, but it is one of the best options for normal use.

Electrical output

The output range of this charger is 12 to 24 volts, with an increase of 0.5 volts. Most likely, there are different voltages that are not supposed to be used normally. But if you have a weird electronic device that comes out of the unusual voltage, this option can be a good option for you. This power supply can produce up to 90 watts of total energy. This model is slightly more efficient than some other adapters and its ideal range is 40 to 60 watts. If the voltage required by your system is in this range, you will enjoy better heat reduction and efficiency.

Connectivity:

This charger has 12 different connectors that are commonly used for most laptops. These connectors alone can support 80% of laptops and notebooks on the market.

Designing

Although not the most compact charger on the market, it can be purchased as a great charger. This adapter has two 5-volt USB ports that can charge up to 2.1 amps. That's great. Because most chargers that have a USB port have only one amp output, which slows down the charging process.

Powseed 70W Universal Laptop Charger

Powseed has been producing chargers and adapters for many years. They produce both high quality OEM replacement chargers and these great universal chargers. Also, the variety of the company's products has made it a reliable brand.

Input Power

Powseed 70W Universal Charger is sold in many countries around the world. For this reason, it supports 120 to 240 volt inputs. This allows you to carry your charger with you anytime, anywhere.

Electrical output

Like most universal charger models, this one is capable of producing a total of 70 watts of output power. If you are not sure what your desired output is, you should multiply the voltage by the ampere, the result is displayed in watts. About 70% of computers require 70 watts of output. Covered voltage ranges include 12, 15, 16, 18, 18.5, 19, 19.5, 20, 22 and 24 volts. One of the advantages of this model is automatic voltage regulation.

Designing

Although this charger is larger in size than other universal models, it instead has more connectors. The manufacturer also uses special adhesives to hold the wire together for ease of movement so that the cable does not become tangled and is easy to move.

Which of the introduced universal versatile charger models is more suitable for my device?

The introduced universal chargers offer almost the same performance. Before buying, you must make sure that the charger adapter is compatible with your computer in terms of voltage, amps and connector dimensions. The next thing you need to check is the power consumption of the device. For this purpose, if you multiply the voltage (V) by the current (A), the power consumption is obtained in watts (W). If the power required by your system is up to 90 amps, you can safely use universal adapters.

Keep in mind that there are few devices that consume more than 90 watts of power. In this case, we recommend you to buy the Belker Slim Universal Laptop Charger, which has a compact design and supports most devices on the market.

If the connector is scarce for you, do not forget to buy LVSun Universal Laptop Charger. Because it also has two USB ports that can be used to charge any device and you will no longer need a mobile charger.

If you have not yet found the right charger, be sure to consider the Powseed Universal Charger. Because it supports almost all devices and has its own required voltage.

USB TYPE-C Laptop Charger Guide and 5 Very Important Tips!

If you are buying a smartphone or laptop, it is likely that the connector adapter connector on your laptop or mobile phone is a USB Type-C. USB Type-C ports are now found on all types of devices, from simple external hard drives to advanced laptops and the latest smartphones. Here we are going to have a complete review of these connectors and TYPE-C chargers. We have also prepared a guide for you to buy a USB TYPE-C laptop charger.

A brief look at the USB TYPE-C connector:

USB TYPE-A connectors, now available on some computers and laptops, entered the electronics world in 1996. USB 2.0 and MICRO USB ports were introduced in 2000 and USB TYPE-C in 2014. Shortly after the release of USB 2.0, USB 3.0 connectors were designed that were much faster than their predecessors. Then TYPE-C is 24 times faster than USB3. In the figure below, we have explained the various internal USB connectors for you.

Although TYPE-C has more pins than other USB ports, it takes up as much space as a MICRO USB. For this reason, the manufacturers of laptops and smartphones are paying attention, and new chargers are mostly of this type.

Data transfer speed and power:

 Data transfer and power transfer speeds in TYPE-C are faster than other USB connectors. Data transfer speed in USB 2.0 is about 480 Mbps. Transfer speed is about 5 Gbps on USB 3.0 and about 10 Gbps on TYPE-C. The following diagram compares the transmission speed between different connectors.

Is USB-C similar to Micro-USB?

According to PC MAG, at first glance, the two look similar. But type-c is a bit bigger. Also, this connector has a higher speed than micro usb. Also, this connector has no up or down direction and we can connect it to the device from any side.

Why is Type-c more popular than other USB cables?

Easy to use and user friendly

USB-C is user-friendly and easier to use. Reversible interface USB-C or Type-C connection is user-friendly and polarity is not a criterion. That is, there are no positive or negative bases in it. USB-C is used in smartphones, tablets, laptops, digital cameras and the like. It also works with different operating systems such as iOS, Android, Windows, Google, etc.

Better speed than USB 2.0 and USB 3.0

The transfer speed in these cables is really great. The transfer speed in Type-C is five times faster than USB 3.0 and about 20 times faster than USB 2.0. Therefore, if this cable is used for charging, the battery charging speed will increase dramatically. If you use USB-C to transfer data and play movies and the like, you can easily play a 4k movie.

USB-C cables with a maximum of 100 watts or 3 amps of power can provide power to almost any device. From laptops to large, high-resolution displays, even some printers.

The following diagram compares the charging speed between TYPE-C adapters and conventional chargers:

Ability to transfer audio and video

USB TYPE-A is commonly used to connect peripherals such as a mouse or keyboard to a computer and notebook. But using type-c is usually used for charging and data transfer, and some laptops and mobile phones have a USB-C port. Type-c can also be used like HDMI to transmit high-speed video and video information. USB-C also has the ability to transfer audio from within. But it has not yet replaced the 3.5 mm jack.

Support for Thunderbolt 3 technology

 Newer Type-Cs use Thunderbolt 3 or Thunderbolt 3 technology. Partacomag has prepared a detailed article on this for you. Click on the name of this technology, which is highlighted in red, to view the article. Perhaps the most useful protocol that a USB-C port can support is Thunderbolt 3. It supports power up to 40Gbps along with reduced power consumption and the ability to move up to 100 watts of power through the interface.

If you do not follow the following tips when buying a USB TYPE-C charger for laptop or mobile, the following items will damage your device:

• The adapter voltage should not be higher than the voltage required by your device.
• The reverse pole causes damage to the parts.

Electronic terms related to the device charging process

Each AC / DC power adapter is specifically designed to accept AC input. The task of these adapters and chargers is to receive the power supply of the power plant and convert it into direct DC output. Therefore, each electronic device is specifically designed to accept a specific DC or AC input. Most chargers are DC.

Method one: Identify the specifications of adapters and chargers

Usually (manufacturers) engrave the relevant information on the label of the device, which can be a guide for you to buy an adapter. If the information was not recorded on the label, it is better to use it with caution. Use a multimeter to check its specifications.

What information is important?

The most important details about your adapter and electronics include: Voltage is measured in volts (V) and current is measured in amperes (A). You've probably heard of resistor (Ω), but this is not usually shown on power adapters. These three terms help to think of electricity as water passing through a pipe.

• Tip 1: In this comparison, we consider voltage as the flow of water.
• Second point: the flow, as its name implies, is in fact the movement of water in the pipe.
• Third point: the resistance goes back to the diameter and thickness of the pipe and is comparable to it.

Changes in any of these variables increase or decrease the amount of power sent to your device. This is a very important issue. Lack of energy means that your device is not charging or working properly. Or too much electrical energy will burn the board or generate too much heat, which will have a devastating effect on your device.

The first point of the adapter voltage:

If you multiply the voltage by the current, you get watts. But watts alone do not tell you whether the adapter is right for your device. You should know this from the adapter buying guide label that is engraved on the product.

Important points about buying a USB TYPE-C laptop charger

Remember that the input of the device must be the same as the output of the adapter. These include: voltage and amperes (watts) and type of polarity. Again, of course, look for polarity according to the + or - or schematic.

Example: If the device has DC + 12V / 5.4A input. Provide an adapter with DC + 12V / 5.4A output. Whatever adapter you have, you need to make sure that the input and output voltage and its polarity are used with your device.

What will happen if you do not use the adapter according to the standard of your device?

As it is known, if you use the adapter according to the standard of your device, you will not have any problem, but if you use the adapter that does not have the output voltage or polarity appropriate for your device, there will be some harmful conditions. We will follow the various errors below.

The second error of low voltage:

If the adapter voltage is lower than the device but the current is the same, the device may be working but this function is irregular. Let us return to the comparison of water pressure. In this case, it acts like when the water pressure is low. Or it comes out in drops of water. The effect of low voltage on the device depends on the pressure of the device. For example, if a speaker does not get enough voltage, two things happen. In the first case, the quality of the output sound decreases, and if the voltage is too low, the device turns off. Low voltage usually does not shorten the life of the device or damage it.

The third error is that the voltage is too high:

In cases where the adapter voltage is only slightly higher than the required value. Then: If the adapter has a higher voltage but the current is the same, the device with high voltage detection will probably turn off. Otherwise, it will overheat the device and damage the useful life of your device.

The fourth flow error is too large:

If the adapter has the correct voltage, but the current is higher than what the input of the device requires, you will not see a problem.

The fifth error is low current:

A few things can happen if the adapter has the correct voltage, but the current (alternative charger) is less than the input requirement of the device.

The device can be turned on, but it requires more power from the adapter than it is designed for. This can cause the adapter to overheat or malfunction. Or the device may turn on but the adapter may not continue. Therefore, it causes a voltage drop.

Consider the following example:

Suppose you have a laptop that needs 19V - 8A DC input, but you use a 19V - 5A DC adapter, your laptop receives the required 19V voltage, but only 5A power. In this case, the adapter works less. It also cannot display its core performance.

Damage to your adapter with less current than needed:

Using adapters that have a lower current than the laptop needs does not pose a particular problem for the laptop. This will only prevent the laptop from turning on and running. And if the laptop can turn on with that current, the adapter will overheat sooner than usual. This will reduce the useful life of the adapter.

Frequently Asked Questions by Customers

Answer: It can be used if your device is not DELL or HP. Provided that your laptop has the right voltage and amps.

Conclusion

In this article, we have prepared a fairly complete guide to buying a USB TYPE-C laptop charger. These chargers entered the market in 2014 and showed good feedback. TYPE-C is 20 times faster than USB 2.0 in data transfer. Also, chargers that use this connector have a very high speed.
