Description

*Expected to be available in Early October.

  • Instant Hot Water, 34K BTU Power: Get hot water on demand with up to 34,000 BTU of heating power and 1.6 GPM water flow. The constant-temperature design helps maintain a consistent outlet temperature and reduce sudden hot-and-cold fluctuations for a comfortable shower experience
  • Cordless & Long-Lasting: The built-in 5200mAh rechargeable battery powers the water pump and controls without an AC outlet during use. Enjoy approximately 120–150 minutes of hot-water operation or 180+ minutes in Cold-Water Mode, with USB-C PD and 12V DC charging options for use on the road or off-grid
  • Patented Auto-Restart: Turn the water off while shampooing or soaping up, then turn it back on—the patented startup system automatically resumes water flow without pressing START again. A 20-minute continuous-run protection feature automatically stops water flow after extended operation
  • Hot & Cold for More Outdoor Uses: Set your preferred water temperature from 95–122°F (35–50°C), or switch to Cold-Water Mode for quick rinsing without activating the burner. Take a hot shower after a day outdoors, wash muddy dogs, rinse horses, clean bikes and boots, wash off beach sand, or clean camping gear at the campsite, farm, or worksite
  • Stable Heat in Cold Conditions: The forced-exhaust system helps improve heat transfer during operation, while the propane-cylinder anti-frost system helps maintain stable heating performance in colder conditions and during extended use
  • Portable, All-in-One Design: At just 12.8 lb., the compact system features a carry handle, pre-installed shower-head holder, accessory storage case, and included 40L water-storage bag. The quick-connect regulator simplifies setup and keeps essential shower accessories together
  • Built-In Protection for Outdoor Use: Multiple protection features help monitor low battery, over-temperature, tilt, flame, exhaust, over-voltage, and continuous operation. The removable pump filter makes routine cleaning easier and helps maintain water flow

FAQ

Q: How long does a full charge last, and how do I recharge it? 

A: Around 120–150 min of hot water (180+ min in cold-water mode) per charge, depending on settings and conditions. Recharge via TYPE-C (about 12h standard / 3–6h with a PD fast charger) or a power bank through the DC 12V port (~4h). 

 

Q: How hot does the water get? Can I adjust the temperature? 

A: Choose a temperature between 95–122°F (35–50°C) on the digital display. Hold the power button 3s to switch between °F/°C. Recommended inlet water: 41–95°F (5–35°C). 

 

Q: How big and heavy is it? Is it easy to carry? 

A: About 12.8 lb and 16.2" × 6.3" × 12.0". It has a carry handle, a pre-mounted shower holder, dedicated storage for the pump/hose/regulator, and an included carry bag. 

 

Q: What fuel does it use? Do I need a water line or home gas connection? 

A: A propane/LPG canister (sold separately; the included regulator fits a 1 lb canister, larger sizes need an adapter). No plumbing needed—place the pump in any standard water bucket (or the included 40 L bag) and connect a canister. 

 

Q: Can it be used outdoors? 

A: Designed to work up to 9,800 ft altitudes. Features staged combustion technology for consistent performance.

 

Q: How fast does it heat up, and how much hot water do I actually get?
A: Hot water comes out in about 3 seconds. It delivers up to 6 L/min (≈1.6 GPM) at a 25°C rise, with the temperature held steady within ±1°C (±2°F) across the 95–122°F range. Rated max heat output is 34,000 BTU/h (10 kW)—enough for a comfortable shower.
