AirForce & Sun Optics ePump video walk-through

Interesting. There was a member post a while back that made something similar only not as compact, I made a comment joking how it looked like something the professor from Gilligan's Island made but was a great invention made with a hand pump.

LOL its definitely a bit of a hardware hack, somebody just told me they recognized the motor and general hardware solution, and suspect its literally a gate-motor.. 

@ShawnLyndy in the US they are advertised at about $850 - I find it way too much for the kit, but needed a compressor that would run in my EV car which do not have a direct battery clip on option, other than that, I would have preferred a Nomad II for less money and faster filing, but those draw 30amp which is too much for the plug.
