A 3/8 inch drive on a 12 V motor, delivering up to 45 ft-lbs. It is for the fasteners a hand ratchet turns slowly, not for the ones you cannot move at all.
Two lithium-ion batteries, quoted at about an hour each and charging in about two, with indicator LEDs. The variable speed trigger is the part that matters in use: it lets you start a fastener gently and finish it properly.
