The BaseCamp B.O.S.S Water Heaters/Showers are the most advanced, portable hot water generators in the world. Simply charge the internal battery using the AC adapter or DC cigarette lighter, drop the pump in a bucket of water, press the ignition button, and dial in your temperature for a great shower anywhere. Or if you have dirty dishes simply select the faucet outlet and you can direct the water from the showerhead to the attached faucet for cleaning hands, dishes, and whatever else you get dirty while out in the field. With the B.O.S.S all you need is a charged battery, water, and a 1lb. propane cylinder to have hot water at your fingertips in even the most remote places. DIGITAL. PORTABLE. CORDLESS. POWERFUL.
