The BSA electric compressor comes with a 240 v power lead and plug allowing it to be used from a domestic socket or alternatively it has jump lead style crocodile grips to connect it to a standard car battery. All you need to do is plug it into your PCP and power it on. It also has a gauge that can be set to the desired fill volume and it will automatically turn itself off preventing over filling. A spares kit is also provided in the box. Our standard filler probes can be used via a quick fill.
