This is a new, unused item. It is a set of 5 units. It's the same size as a regular ratchet handle, but it's motorized. It stops at 1 N-m when powered, and manual tightening/loosening is possible up to 60 N-m. It supports forward and reverse rotation by changing the bit. Charging is done via USB Type-C. Applications: Tightening and loosening bolts and nuts. Thank you.
