VEVOR 4500 PSI 500W Converter, Auto-Stop

Overview

One of VEVOR's best-selling PCP compressors (100+ a month on Amazon). A 500W converter is built in, so it runs from a 120V outlet at home or clips to a 12V car battery in the field. The display shows pressure and temperature in real time. Set your target, and it shuts off on its own and shows "E4" when the fill is done. VEVOR says it uses a linkage drive instead of the usual cam design, for less noise, better heat handling, and fewer mid-fill burnouts. It has a built-in oil/water separator and comes with an 8mm quick-connect hose, battery clamps, and a spare parts pack. VEVOR rates it at about 25 minutes to fill a 0.5L tank from 0 to 300 bar. There's no activated carbon, so add an external carbon filter if you ever fill a scuba bottle.
