I've had good luck with The harbor freight electric 1/2" drive impact.

It does most stuff OK, and really speeds getting the wheels off and on.


Get the Torx sticks so you can mount the tires, and bring it with you so that
the idiots at the tire places don't torque your wheel studs to 800 lbs.
which seems to be a trend everywhere, requiring you carry a 15MM impact socket a 24" 1/2 breaker bar and a 3' hunk of steel fence post to get wheel lugs free. Don't let a tire monkey near your car without a torx stick when mounting tires!

Both items are short money compared to garage quality air guns.

Lots of comparisons are published online for both corded and cordless impact wrenches. "Generally", the pricier they are the better they're rated. The sky's the limit. Pick a price range and then go read reviews.

I don't own one :( But if I were in the market I would look for one that is fairly stubby front-to-back so that it can get into tighter places, yet still pack the required punch.

It also matters whether you are a professional or weekend warrior. Well, come to think about it, if you were a pro we probably wouldn't be having this conversation.

Good luck and happy hunting.
