Best wholesale laptop adapter manufacturer today? 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 information at 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.
Once you’ve found a charger that provides the correct amount of power, the next step is to determine your polarity. For barrel-style plugs, you’ll see a symbol with a “+” and “-“ sign, connected to a ring and a dot. The symbol connected to the outer ring represents the polarity of the outside of the barrel. Similarly, the sign connected to the dot represents the polarity of the inside of the barrel. Most devices use an adapter with the positive connector on the center, but there are exceptions.
Advantages of buying an OEM laptop charger: It’s exactly the same in function to your original charger, so you can expect the same performance; Providing you buy the correct charger, it’s guaranteed to work with your laptop. OEM chargers can be difficult to source, particularly for older models of laptop; the OEM manufacturer may no longer produce the charger for your laptop. They can be expensive, depending on availability. There are an abundance of fake or counterfeit OEM chargers sold by private sellers across marketplaces such as eBay and Amazon which are potentially dangerous. These can be incredibly difficult to identify, even when comparing the original with the counterfeit in person. Fake chargers often lack various features that make chargers safe, such as temperature control and short circuit protections.
