Hello,
I bought such a miracle produced for the US market:
ONE-KEY (TM) FUEL (TM) hammer drill / driver
ONE-KEY (TM) FUEL (TM) impact driver
This set includes two batteries and a 110V charger, photos below:

I am asking for advice on how to convert it to 220V.
I can solder and I have the equipment. Thank you in advance to the gentlemen referring to the nearest electronics, I want to do it myself. I do not have a schematic diagram, but if detailed information is missing, I will try to get it.
greetings
