How to Buy a Laptop Charger Online

If your laptop's power adapter is lost or broken, how to buy a cheap replacement laptop charger? The original laptop adapter of the same model can be applied certainly, but the original adapter price is very expensive. This article tells you tips for choosing a replacement laptop adapter.


Part 1: What is an ac adapter for a laptop?

It converts your power supply 110-240V AC into a smaller, stable DC voltage for use in small devices. Usually these are necessary to charge the battery or power the device.

Part 2: How to choose a replacement laptop charger?

1. Choose brand chargers

First consider choosing the same brand as the original adapter. I suggest you buy the original laptop adapter. Professional brand products will not cause damage to the battery and laptop due to poor quality charger.

How to determine the laptop model and purchase the adapter:

1) Product name: Identify your notebook in a series your product belongs. You can see the model label of the notebook in the lower right corner of the screen or in the upper left corner of the keyboard. You can often see a series of letters and numbers.


2) Serial number: This is the identity number of the notebook. For example, HP notebooks, you can use this serial number to query the warranty time of the product and related parameters of each component, including information about the adapter at HP support site.

For more information on laptop numbers, you can refer to HP's Support,and other brand rules are similar.


2. Purchase new laptop adapter according to purpose

Buy a conventional adapter for your home and office laptop power adapters. If you need a laptop power adapter for use in your car, you need to buy a notebook car power supply. You can purchase a car laptop power adapter for all brands of laptops at GEMWON Mall.

3. Identify V, A and connectors

Confirm which brand the laptop is. How many voltage and current are written on the label on the back of the old charger (generally written in OUTPUT) and the connector of the charger is round or square, or porous.

For example, if you buy anew laptop charger online with a current higher than the original adapter current, you can use it.

If the newly purchased adapter current is lower than the original configuration, the emergency can be charged in special circumstances, and the battery and laptop will be damaged after a long time. So, don't buy a laptop adapter with an output current lower than the specified output current.

4.How to choose the right laptop adapter with the right voltage and current

The general rule is that the voltage is the same and the current is equal to or exceeds the rated current.

so, if you choose an AC adapter to make sure to check the following:

The adapter output voltage matches the rated voltage of the device.

The adapter outputs a device that is greater than or equal to the rated mAh or A.

This plug is suitable for your device and has the correct polarity.

5. Select the plug

You want to have the size of the adapter plug, just check the adapter measurement, these types of connectors have two measurement methods.

OD - the outer diameter of the plug.

ID - The inner diameter of the plug.


For example, there is plug that parameter is 5 mm x 2 mm, which represents an outer diameter of 5 mm and an inner diameter of 2 mm. If you enter the store to buy a laptop replacement charger,you can compare and test the connector size, or if you have tools, you can measure the port size yourself. ID an OD measurements must match and the new adapter can connect properly.


6. The plugs have the same polarity

Usually the polarity of the symbol on your notebook is positive and negative. The adapter and device must match, so be sure to double check the symbols on the AC adapter and the device displays the same polarity.


GEMWON is a wholesale online shopping mall for laptop accessories, and offers all original laptop adapters for LENOVO/ASUS/HP/TOSHIBA. You can wholesale original laptop adapters less than $3, which is a good online shopping mall for laptop parts.

Above is about how to match charger with laptop. If you are purchasing an adapter, but you don't know about the adapter's parameters, then you can provide Model of the laptop and GEMWON will find the right adapter for your laptop.
