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.

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.

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.
