Joolca Power Bank
24,000mAh. Airline approved.
A 24,000mAh portable battery built to power your HOTTAP pump, charge your devices, and keep everything running off-grid. USB-C PD 3.0 charges and delivers power up to 70% faster than standard USB. Four neodymium magnets let you stick it to your HOTTAP, vehicle, or any metal surface. Airline approved as carry-on.
- 24,000mAh / 86Wh capacity: Enough to run your HOTTAP pump for around two hours (that's roughly twelve 10-minute showers) or charge a smartphone about eight times.
- USB-C PD 3.0: Charges connected devices and recharges itself up to 70% faster than standard USB chargers. Smart chipset detects each device and delivers the right amount of power automatically.
- Three output ports: USB-C, USB-A, and 12V DC. Power the HOTTAP pump, charge a phone, and run a light at the same time.
- Fully automatic with the HOTTAP pump: Leave the Power Bank on. The pump turns it on and off as needed when you flick the shower or faucet switch. No walking back to press buttons.
- Magnetic mounting: Four strong neodymium magnets let you stick the Power Bank to your HOTTAP, vehicle panel, or metal jerry can. Stays put in transit.
- Fast recharge: Fully charge from a 60W USB-C wall charger in 90 minutes. Also charges from a car's USB-C port, cigarette lighter socket, solar panel, or laptop. Supports pass-through charging, so it can power devices while recharging itself.
- Airline approved: Under 100Wh, so it's approved for carry-on luggage.
- Includes pump cable: Comes with a DC to DC cable that connects directly to your HOTTAP pump. Optional 12V Power Splitter (sold separately) lets you power both the pump and HOTTAP 12V Power Adapter from the same Power Bank.
