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.
