DEWALT 20V MAX Air Inflator

I picked this one because it runs on the DEWALT 20V MAX battery platform, so it is a handy addition if you already have those batteries, and it also works from a vehicle's 12-volt outlet. I also like its digital gauge and automatic shut-off, which help you hit the right pressure without guessing. Before you buy, check whether this tool-only version suits you, since it does not include a battery or charger, and confirm it covers your tire pressure range.
