Auto Care TMX437 12V Automatic Air Compressor

As with our Best Buy, this has a padded, zipped case for life in the boot. It also comes with a decent removable gauge, incorporating presets, plus a long air line complete with a screw-on valve connector and easy-to-use separate open storage. Plus, there’s a pump to match that impressive spec, as it delivered 8psi in a minute’s running.
