Welcome to the forums! First question....why? You will need 750 to 1 gear reduction unit to overcome the speed of the motor. Over all the unit will weigh about 50 lbs. You'll need a way of moving it, aligning it with the shaft of the jack and allowing it to move as the jack moves. OR, you could buy an electric 1/2" impact driver, fit it with the appropriate socket and do what the normal lug nut wrench would do. (provided it has a nut and not an incorporated handle) We'll wait for the "why" thingy first. Unless you use this thing every day, I would just use the wrench that came with the jack.

I've used all kinds of attachments on mine - speed wrench, cordless drill, electric impact wrench, pneumatic impact wrench - all of them work fine for me.

I'm with Chandler, the 'why' behind your request is going to be important.
