Coleman Hot Water on Demand H2Oasis Portable Water Heater

Always have hot water whenever and wherever you need it with a Coleman Hot Water on Demand H2Oasis Portable Water Heater. Using technology similar to a tankless water heater for your home, this propane-powered heater dispenses hot water in as little as 30 seconds. All you need to do is connect the pump to the included 5-gallon water carrier, connect the hoses, dial in your temperature and your water will be heated up to 54 °F with a maximum temperature of 125 °F. It's perfect for washing the dishes, taking a shower, or preparing a hot beverage when you're in the great outdoors. The shower head can be placed in the adjustable holder for use as a sink faucet, or you can detach it for use as a handheld sprayer with the 6-foot, non-kink hose.

A built-in lithium-ion battery, which can be charged from your car outlet with the included charger, powers the electic pump and LED display. When you're ready to pack up, you simply disconnect the hoses and you can store everything in the mesh bag until the next time you need comfortably hot water while enjoying an outdoor adventure.

Terrible product
1 Star
Terrible product
Did not use it until after the return window was closed. The hoses leak without pressure even going through. You have to charge it before even going out of town. And when I threaded onto the water holder, provided it leaked everywhere and soaked our floor. Now they will not allow me to return it.I was never able to get the product to even work or spit water out not even cold much less hot
