Battery powered bolts remover / tightener

[atom0101]

Hi guys, just wanted to find out where are those electric or battery powered bolts remover / tightener on sale? I see the auto garage usually uses the ones that are compressed air driven, and Midas sells them, but since I wanted to use at home, I needed something that runs on electricity (battery would be even better!). So if anyone know where they sell them, please tell me!

Thanks all!

Electric screwdriver with bolt fittings?

normal electric drill with the right fitting.

how often do you need to change tyres that this would be necessary?
