Wholesale laptop adapter supplier with LaptopRepair? Find your laptops wattage: When using our site, this isn’t essential as we list replacement power supplies based on their precise model number, and they’re guaranteed to work for your device. However, it’s always good practice to understand the power requirements for your laptop. The main element you’ll want to look for is the output voltage for the charger (sometimes referred to as DC voltage). Check in your laptop manual for the voltage requirements or look at the original power supply if you still have it. It will often be something like this: OUTPUT: 19VDC 3.42A By multiplying the output voltage and amps you can calculate the total wattage of your machine, in this case 65W after rounding up.

The output tip needs to match. There are many types of tips. There is the traditional barrel tip which is a simple barrel shape connector with a hole in the middle. These are measured in the form of 5.5mm x 2.5mm which us the external and internal diameter of the tip. These need to match or else the connector will not fit or will be too loose. Some chargers have a small pin in the centre and some manufacturers (HP and Dell) that have what is known as a smart tip, where there is some electronics in the tip which is used to communicate with the laptop to ensure the correct charger is connected. Whilst these tips are physically the same size, you can not use a Dell charger on a HP laptop or vice versa.

Unlike voltage, amperage does not be exactly matched to your device. You can use a higher amperage charger with a lower-amperage laptop, but not vice-versa. So a 4.5-amp charger will work with a 3.25-amp device, but a 3.25-amp charger won’t power a 4.5-amp device. Keep in mind that it’s sometimes possible to use a lower-amperage charger if the numbers are close enough. However, this is a Very Bad Idea. In the best case scenario, over-power circuitry in the charger will deactivate it. In the worst case, the charger can overheat, permanently burning out the circuitry or even starting a fire.

If you’re planing to buy an OEM power supply for your laptop, do make sure that its from a reputable company who can provide assurances on their chargers. Universal chargers are commonly available as replacements for many of the leading laptop brands. Some even span multiple brands and are packaged with multiple sets of ‘tips’ or ‘pins’, the part of the charger that connects directly to your laptop. As we covered in our help guide on power supply pin sizes, measuring the pin size required for your laptop can be a real challenge and impossible if you no longer have the original charger to hand. Universal laptop power adaptors are always produced by third party brands, and the same power supply is often re-branded by different companies across popular marketplaces.
