Wholesale laptop adapter supplier in China? 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.
The first thing you’ll want to look at is the adapter’s output voltage. This is extremely important, since a device will only work if it’s receiving the correct voltage. Most laptop chargers are rated for 3, 5, 6, 9, 12, or 18 volts. However, you’ll want to check your owner’s manual or original charger to verify. Voltage corresponds to a circuit’s maximum capacity. If you imagine the circuit as a river, the voltage measures the width of the river bed. Amperage, on the other hand, represents the intensity of power delivery. So a high-voltage, lower amperage charger is like a wide, slow-flowing river. A low-voltage, high-amperage charger is like a narrow whitewater rapids.
There are no guarantees on quality. Many of the universal chargers we looked at on eBay and Amazon came with no mention at all on warranty either. By nature of a universal charger, many of its parts are removable (such as the pin section). These can be wobbly or poorly fitting and will degrade over time. Finally, many universal laptop chargers have a switch to manually select the required voltage. Plugging the charger into your laptop with the wrong voltage selected can cause irreversible damage to your laptop. In summary for universal laptop power adaptors, we can’t recommend them as there are too many factors that can risk causing damage to your laptop.
