I have an old laptop which I no longer have the charger for. I ordered a new charger for the same laptop series, but the plug is too large, and it is unlikely that I will find the same adapter (Acer is difficult with their proprietary plugs).
I have an idea to connect the power supply directly to the laptop. 15.2V is the battery voltage. The charger provides an output of 19V at 3.42A.
Is it possible to do something like this?
