1/2 Inch Drive Corded or Battery Impact Wrench

[docsouce]

Primary use would be to change a flat tire when I'm on the road. If I get a corded wrench I would need to start the generator to use it. I would also need an extension cord. If I get a battery operated wrench all I need to do is make sure the battery is charged. Corded Pros: less expensive, takes up less room and I think it would more powerful than a battery operated gun. Cons: need to have the generator running to use. Battery: Pros: ready for immediate use. Cons: takes up a little more storage space, must be charged to use, cost more and this is just a guess, doesn't have the same power as a corded gun. My current set up is a 3ft length of 1 1/2 pipe and a 3/4 inch breaker bar which will work fine but I'd like to simplify my approach.
As always your opinions are valued.

Cord-free is my choice. Hopefully you never have to change a flat on the road.

Actually the cordless will likely take less space than the corded. A Dewalt 1/2" cordless impact will be more than equal to a corded impact. They do cost more, but you can usually pick up a used one off Facebook Marketplace for a very good price. The corded impact really has only one possible plus: a new one is cheaper than a new cordless. But if you go used, that's a wash.

IMO a cordless assets totally outweigh the corded assets. No contest.
