Basic type: Mainly screwing general screws.
You can choose 4.8v, 6v, 7.2v, 9.6v electric screwdrivers, most of which can be 3.6v, but the limit is too much. Domestic and foreign brands are free. The voltage is different, and the actual experience is different. And generally fixed 1/4 aperture.
Ordinary type: In addition to screwing, you also need to drill small wooden holes and drill metal holes.
At this time, it must be 10.8v, 12v, or even 14.4v. The general torque of 12v 10.8v is within 30 Nm, and the width of 10mm can be adjusted. At this time, it is best to have 2 batteries.
Quasi-professional type: Reaming, drilling, production of various materials, and the pursuit of expansion, bearing wall punching. At this time, 10.8v is somewhat far-fetched, and the 18v.20v hand drill is used. The scheme is as follows:
