My experience with electric impact wrenches suggests that a "cross
wrench" is a heck of a lot more reliable for getting lug nuts off. Add a
can of antiseize and they come off nicer the next time.



The OP needs a good cordless impact for present... and I wish I had a
suggestion.

However, having said that I agree that a big, cross type rim wrench is
the right technology to carry for boon dock emergency situations.
Simple, reliable, powerful and practically indestructible.
