Also, using a notebook this way can shorten battery life. In this case, if you use a source with more than 19 Volts, there is a risk of damaging the computer’s circuitry and battery, while a unit with less than that may be insufficient to charge the battery on time and keep the notebook running at the same time.
In this case, just do the opposite way and divide the power by the voltage to discover the intensity in amperes: 90 Watts divided by 19 Volts results in 4.74 amps, for example. It is rare, but the source may bring only the voltage value (in Volts) and power. Multiplying these two values, we found that this source has 90 Watts of power. In the above image, the charger has 19 Volts and 4.74 amps output.
If you do not have access to the original source or the information is unreadable for some reason, you can discover it by consulting manuals and official computer data sheets in the manufacturer’s online documentation.
