      Comments about ProMariner ProTournament 300Quad Onboard Battery Charger:

      We use this product on Pump trailers, blenders and the data van, all used for Fracking in the Oil and Gas Industry. They are all mounted outside in the elements. So far they have withstood Vibration, sand and anything else out here on a natural gas well site.
