Check the listing for details. 2 Coleman HWOD H2Oasis Portable Water Heater On-Demand Hot Water. Untested! Read. Color: Red, Condition: For parts or not working. Listed at 250.00 USD. Two Coleman h2 oasis hot water on demands. For camping. Storage unit find these units are untested and I believe are missing some accessories. One is missing the gray knob. Also one is missing a little rubber foot on the bottom so it means a little bit . You have the two heaters one home electrical plug, and one for the car plug. I don't know if the lithium batteries need to be replaced out of them or not. I plugged them both to charge. The green light comes on. They run off a propane. I don't really know what the electrical part of it is in it. Any questions feel free to reach out. I'll try to answer best as possible. Both could work or none could work. I'm selling for parts of repair as is.
