This is a 12 volt driven tire air pump; see pics for model and other details.
I haven't used it in years. I plugged it into a 12 volt outlet the other day and it didn't fire up. Could be electrical or the pump could be bad. If you have more mechanical ability than I do (which is a low bar) you might be able to make it work. The price is right.
I forget to check BisMan messages, so text me. THX!
