Everything you need to run your HOTTAP V2 and 12V pump from a single portable power source, with no D-cell batteries and no vehicle connection. The Power Bank provides up to two hours of runtime for both the heater and pump. The 12V Power Adapter replaces the battery box on your HOTTAP V2, and the Power Splitter connects both the heater and pump to the one Power Bank. One power source, one setup, fully off-grid.
