It still took about 10 minutes but it came off
The battery driven ones are great. I use a 18V bosch at work that's rated to 200nm. I use it on everything from m6 to m16. It has a nice balance between power and control so that you can gently tighten small bolts without breaking them.
I have used it a little when working on my car, but it's often a little to large to reach in those awkard positions.
I hope that the 12v version will be better for those tight spaces. It's only rated to 115nm so it may struggle with seized bolts and wheel lugs. But I think it will come in handy in many situations.
I also have an air powered in my garage, but the hose is always in my way, so I only use it to remove wheels.
