A while back I came across a great deal on these. Its the Black & Decker
power screw driver (I can't remember the model) But it had 40 inch lb of
torque and cost only $14 regular price. It was the driver only it did not
have a battery or charger system (Those were extra) The unit operated on
3.6 volts don't know the current draw.
