Best portable air compressor for car tire?

I had a $20 Campbell Hausfeld compressor from Lowe’s or Home Depot for a good ten years, although it just gave up the ghost. I’m about to order a Duracell Powerpack (around $75) as a replacement because I think I’d like having a cordless compressor and a minor power backup source.

Whatever you do, don’t trust the air pressure gauge on a compressor. They can be way off.
