Portable air compressor for tires

Unless you are using it for airing up and down there isn't really a need for any of the larger ones. I doubt it'll fit behind the seat. Get an 85p (cigarette lighter plug) or 88p cables to the battery.

Or 30-40 bucks at harbor freight for their little cigarette lighter model. If you aren't using it to air down/up it'll last you years.

Viar 300p-RVS should be all you need.

 

I love my ARB portable air compressor that attaches to the battery. I can use it on any vehicle which is definitely a plus. Storing the air compressor is another issue.
