Why you'll love it
Run your HOTTAP pump for around two hours, or recharge a typical smartphone up to approximately eight times.
Charge compatible devices and recharge the Power Bank faster than with standard USB charging.
USB-C, USB-A, and 12V DC let you run your HOTTAP pump while charging other compatible devices at the same time.
Leave the Power Bank switched on and your HOTTAP pump draws power whenever you turn your shower or faucet on.
Four powerful neodymium magnets secure it to your HOTTAP, vehicle, metal jerry can, or another suitable steel surface.
Recharge in around 90 minutes with a compatible 60W USB-C charger. You can also recharge from compatible vehicle, solar, or laptop power sources.
Continue powering compatible devices while the Power Bank itself is connected to a charging source.
At 86Wh, it sits below the commonly permitted 100Wh threshold for passenger carry-on lithium batteries. Always confirm your airline's requirements before travelling.
Comes with the DC-to-DC cable required to connect directly to your HOTTAP pump.
