Answer 1

How to find out how many amps this power supply produces?

It's not that easy. The criterion is an overload in power, and such an overload is expressed in overheating, in the limiting case - in the combustion of the PSU.
So if you approach this issue according to the classics, then you need to slowly add a load to the power supply, constantly monitoring the temperature of the power transistor, rectifier diode and transformer (this should be done gradually because the temperature is an inertial thing, it is not set instantly). On kraynyak you can control the temperature of the case from the outside, holding it in your hand. If the case has warmed up to 45 ... 50 degrees, then this will be approximately the maximum load current (branded PSUs from laptops have this temperature when lying on the table for a long time). It is clear that there is some risk in such a check - this is the price for a torn off sticker.

Answer 2

It's not destiny to look at the batteries of the laptop itself?
also score the names of the laptop on Ali and look at the characteristics of charging

Answer 3

Sometimes the power is indicated on the markings on the board. Or sometimes you can find out the power by googling the name of the board.
