Top rated wholesale laptop adapter manufacturer and 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. Read additional info on laptop adapter replacement.
Watts is calculated by multiplying the Volts by the Amps. Therefore a 19V charger with an Amps rating of 3.42A would be a 65W charger 19V x 3.42A = 65W. The higher the Amps the higher the Watts, provided the Voltage remains constant. It’s a Maximum Rating. The Amps and Watts rating on a laptop charger is a maximum output rating. This means that the charger is capable of outputting up to the maximum Watts rating. ie it can push up to x Amps of water through the pipe at a force of up to x Watts at the pressure (Volts) provided by the charger. However, to avoid any damage to your laptop it’s usually a good idea to check the polarity against that of the laptop or your original charger.
Regardless, it’s essential to get the right polarity! A charger with the wrong polarity can cause your laptop to overheat. If your laptop is equipped with a polarity fuse, the fuse will blow. You’ll need to replace the fuse, and you’ll still need a new charger. If your laptop doesn’t have a polarity fuse, you’ll potentially cook your entire machine. Compared to everything else we’ve discussed, plug measurements are relatively straightforward. There are two measurements: one for the inside diameter, and the other for the outside. Both are measured in millimeters. This is generally noted as “5mm OD x 2mm ID” or something similar. If need be, you can also check by simply plugging it in. Provided the polarity and power supply are correct, connecting the wrong size adapter won’t do any harm. It just won’t work.
