Attempting to transfer a cordless screwdriver to a wire

Hello dear readers. Today I will talk about trying to convert a cordless screwdriver to a wire.
Trying to convert a cordless screwdriver to a wire

This idea came to me after I discovered a 12V screwdriver without a battery.
Trying to convert the cordless screwdriver to the wire At first I came up with a brilliant idea (which in the end failed): take a battery charger and connect it directly.

If you look closely at the photo of the charger, which is presented above, you will notice a very important detail, according to which we can conclude that the screwdriver will not work. The whole “snag” lies in the voltage of the charger. The charger gives out 18V, while the screwdriver I have is 12V. But it's okay, I have a “shura” 18V.

I decided to follow through with this idea, so I got into my “bins”. Having found a power supply unit there that produces 22V, I decided to give it a try.

The poor screwdriver has worked. But the main problem appeared – this was the current that the power supply was giving out. It was only 450mA. This was not even enough to tighten a small, thin self-tapping screw. From this we can conclude that the voltage of 22V is quite enough, but the current must be at least 2A.
