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.
