Question Laptop Charging Circuit

[Cameron231099]

Just bought a used Inspiron 14 5425 that comes with a standard 65w charger, a massive downgrade from my RTX3070 MSI GF66 Katana which take a 245w charger.

This got me wondering about how much power the Inspiron would actually accept and if I should keep the higher wattage charger, but I can't actually find any solid info on what the maximum wattage may be.

Is there anywhere I am supposed to be able to find this info? I've tried searching for the charging circuit diagrams, but can't find anything useful, so figured I would ask someone more knowledgeable.

Cheers.

You might have to ask Dell. I don't see any published numbers on C ratings for the battery, available additional adapters.

65W 19.5V charger is basically 1C rate for the 15.2V 54Wh battery that comes with it. Being a smaller battery, 65W may very well be the maximum. You can get something like a 125W Dell charger, it won't hurt the laptop.

I doubt your MSI charger would fit.
