Understanding how a laptop charger works

The operation of a laptop charger depends mainly on the characteristics of the base charger and those of the laptop power bank . In fact, the two groups of characteristics must agree in every way. The elements to be matched are as follows:

  • The necessary electrical voltage (in Volt);
  • The intensity of the maximum current (in Amps);
  • The power of the current (in Watt).

The characteristics are identical in Input or Output. Now, how to check if your pc charger and power bank match? Take this practical example. Your laptop charger displays the following information: Voltage = 20V, Current = 5A.

This information means that your charger needs electrical energy of 20 Volts and 5 Amps at most. If the power is not mentioned, know that it is the product of the voltage and the current. In this case, the required power of the current is 90 Watts.

All you have to do is look for a power bank for laptop that has the same specifications. If there is a mismatch (high voltage), the laptop could be seriously damaged.
