So i was thinking of buying a craftsman 19.2 volt wireless tire inflator for flats out in the desert when im far from camp, i always keep plug kits but no on board air. What are some of the things you guys use to air up when not at camp? What are the best small battery powered air pumps? I would only need to pump 10-12 psi. Ive heard some cant fill a regular size tire which is fine. Since a sxs tire is small.
