Buy a laptop and notebook charger and 5 important points!

 If you are reading the article on buying a laptop power adapter and charger, there is probably a problem with the process of using your laptop, your device may not turn on or the issue of not charging the laptop battery has caused you trouble. If you are planning to buy or replace a laptop charging adapter, it is best to review this before taking any action. Of course, how the adapters work is another matter. Which I have dealt with separately. In this article, we want to acquaint you with the important and significant points that are important for buying a laptop charger adapter. Please stay with Partako.

Laptop charger application

The laptop charger adapter has two functions. The first is to send the electricity needed to turn on the laptop and the second is to provide the energy needed to charge the device. Adapters may be similar in many ways, but there are a number of important things to keep in mind when using the adapter to avoid damaging your device.

Important tips for buying a notebook or laptop charger

Chargers have several technical features. Each of these features makes a difference or similarity between them. The most important point when buying a laptop charger adapter is to pay attention to the adapter watt. Carelessness and ignoring the characteristics of the charger, such as the type of output and also not paying attention to the adaptation (voltage and amps) can damage your device.

1- The first point is the connector and socket of the adapter (charger)

First check if the adapter you choose matches the charger of your device in terms of connector or not! Laptop charger connectors are usually round except for some special cases, many of these connectors are similar in appearance but it is good to know that each part of the charger connector may be different.

Important points about the Cantor laptop charger adapter!

Connector 5.5 * 2.5 mm (round) is the most common connector and is known as the reference connector.

Even in some similar sizes there is still a difference.

When buying a laptop charger, pay attention to the inside and outside diameters of the socket.

Some connectors are specific to one brand or model.

Newer laptops also support the USB TYPE C connector.

The reason why it is important to check the charger head and laptop

The question here is whether it is possible to use a charger with another brand but with the same voltage and amp as our laptop charger or not. I must say that this is possible. The device will not be damaged due to brand mismatch. You should know that the laptop adapter or charger is only responsible for supplying power with a certain voltage and amp. The important thing to keep in mind when using the charger is that the sockets are the same. If the purchased connector (charger) does not match your device, serious damage will be done to the laptop. If the laptop charger socket or plug is larger or smaller, the laptop power jack may break and be damaged. Also, if it is loose, the current may not be transmitted properly.

To specify the output voltage and amps: The expressions V for voltage and A for amps are printed on the body or label of the charger.

2- Voltage and amps mean life and death

As I said before, the important thing to pay attention to is the voltage and amp of the adapter. Even if the head of your laptop charger connector is the same as the other similar adapter, never replace the adapter before making sure that the amp and voltage are the same!

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

2- Voltage and amps mean life and death

As I said before, the important thing to pay attention to is the voltage and amp of the adapter. Even if the head of your laptop charger connector is the same as the other similar adapter, never replace the adapter before making sure that the amp and voltage are the same!

The duration and extent of the damage may vary depending on the high voltage.

Sometimes the device does not turn on and in some cases your laptop will be damaged after a while.

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

The replacement conditions of the laptop charger adapter are such that the output voltage of the adapter must be exactly the same and its current can be equal to or greater than the original adapter. When preparing a new adapter, if the adapter with the same output amp is not available, you can use the adapter with a higher output amp, but only if it does not change the performance of the laptop, such as hanging the laptop, touching the touchpad or mouse.

In short, voltage means the amount of electricity and amps means the intensity of its current. The adapter that connects to your laptop should not enter the voltage higher than what is intended for it if you have connected the adapter to the device improperly. Depending on the percentage of voltage that is exceeded, the speed and type of damage varies. If the charger voltage is higher than the laptop, the device heats up quickly and the smell of burns rises from its board.

So far, we know that we have to pay attention to these points when buying a charger

• The same voltage and amps are ultimately equal to the watt adapters
• Full adaptation of the adapter in terms of socket
• Quality of body and adapter parts
• Warranty and support services

3- What is the quality of the adapter?

Original adapters are exactly the same in appearance in many cases as copy adapters. The production of the adapter frame does not require special technology and design; However, most of the original adapters of the adapter brand are engraved on the frame, but this case is also used in copy adapters. Therefore, the similarity of appearance is not considered as the main criterion of the adapter. Cited.

How do I know my adapter is counterfeit !?

These adapters are sometimes similar in weight to the original adapters. The main adapters are heavier in weight, and this happens naturally. The original adapters have many components, each of which has its own value, but the copy adapters are light in weight. They are wet and use more metal to bring its weight closer to the weight of the original sample.

Disadvantages of non-original and substandard adapters!

Relatively high heat generation in these adapters, which is an unsuitable design.

Protective faults in non-original adapter circuit.

The main board is a single-layer or one-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.

Important note !

Due to the unprofessional design of these adapters, the laptop used is always exposed to severe damage, so that the adapter may remain intact, but its improper output will reduce battery life and severe damage to the motherboard and even burn the notebook motherboard.

Professional Assessment for Buying a Laptop Charger

The weight of the charger or the plastic color of the adapter body is often the standard of quality. It is true that many low quality chargers weigh less, but there are many low quality chargers on the market that have ideal weights in different ways. In any case, appearance is not a sign of quality.

Only a voltmeter and ammeter can professionally detect the quality of laptop chargers. By connecting the charger to this measuring device, if the voltage and amps are displayed exactly what is written on the charger, and if these figures do not change during a certain period of time, such as half an hour, it means that the charger is of good quality and standard.

Purchase laptop chargers from reputable stores

First of all, it is necessary to know that 99% of the laptop chargers available in the Iranian market are not (completely original). This is not bad news, because the quality of original chargers and non-original chargers are not much different in terms of good quality. And as we all know, the technology of a laptop charger or adapter is not so sophisticated that its makers have failed to build it. And that the charger of non-original laptops with quality and mainly with the original name can be found in abundance in the Iranian market. Just go to reputable stores to get them.

Guide to buying a laptop charger with a valid warranty and guarantee

What can make you think about quality when buying a laptop charger adapter is the product warranty or guarantee. By buying a laptop adapter with a warranty or buying a laptop charger with a warranty, you will ensure that the quality and long-term durability of the product will be reliable and predictable because, as we said, the quality of manufacturing and production of adapters is varied. Make sure your product, even if its product does not have an official warranty card, guarantees it itself, a seller who is confident in the quality of his product will pay for the credit so that you can 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

Warranty or guarantee that is considered as a guarantee sheet for the goods from the moment of arrival:

The initial guarantee 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 concluded orally or in writing.
• The guarantee contract can be included in the goods invoice.

Of course, the product warranty also has conditions!

It is true that electronic goods have a certain useful life and it is unreasonable for a laptop charger to fail on the first day of use, but a quick charger failure is beyond the scope of warranty if it occurs due to improper use or physical damage. As:

• Cut or tear the adapter cable wire
• Peeling off the connector or breaking the middle pin 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 that may lead to adapter breakage
• Impact due to the adapter falling through the charger and hitting hard surfaces
• And other defects that cause your adapter to expire suddenly.

4- The easiest way to identify the adapter is to pay attention to the international product code

  I have already spoken in the article introducing part number as a criterion for measuring and matching the product. According to the international product code with the name of the part number, you can find the type of your requested part and replace the desired part without any need for other information. Knowing part number has other benefits as well. I invite you to read the full article about part numbers.

What is Part Number

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.

5- What is the difference between the size of different types of laptop adapters?

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 have to say: In general, the criterion for 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 and dimensions 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.

Summary of Laptop Charger Buying Guide

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 can be replaced for my device because of its similarity in appearance. Unless the technical specifications of the two are exactly the same. You should never buy an adapter to buy. You can find out the real model of your adapter from the part number. Here is another important point. That many factories produce rechargeable models that have different qualities. 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 current 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.
