Product Features:

6L Large Fuel Tank & High Fuel-Efficiency
High-efficiency combustion consumes as little as 0.03 gal/h(0.13 L/h) (Level 1) to 0.09 gal/h(0.35 L/h) (Level 10). Paired with a 1.6 gal (6L) fuel tank, it delivers up to 46 hours of runtime at Level 1, 28 hours at Level 5, and 17 hours at Level 10. Running an 8-hour night on low heat uses only ~0.26 gal(0.98 L) of diesel—delivering maximum cost efficiency for off-grid campers, truckers, and vanlifers.

±2°C Precision Control Constant Temp
An optimized temperature algorithm tightens the auto start/stop threshold to ±2°C for extreme sensitivity to subtle ambient changes. By adjusting continuously in compact spaces, it prevents drastic temperature swings and creates a stable interior micro-climate, ensuring uninterrupted overnight comfort without manual panel tweaks in the middle of the night.

IPX4 All-Weather Waterproof Protection
The entire unit has passed strict lab testing and earned the internationally recognized IPX4 waterproof rating, with both the main body and wiring treated for water resistance. It repels rain, mud, and road spray from all directions while fully protecting the internal motherboard and motor.  Built for camping in the rain, parked in snow, or driving muddy off-road trails.

Adaptive High-Altitude Mode
The intelligent control system automatically detects elevation and adjusts fuel injection based on ambient oxygen levels. By maintaining clean, stable combustion in high-altitude environments, it prevents flameouts and black smoke. Delivers continuous, reliable heat without loss of efficiency across alpine valleys and mountain passes.

Leak-Proof Fuel System
Equipped with an upgraded two-way pressure-relief valve fuel cap that balances internal tank pressure during travel. Prevents fuel overflow, tank collapse, and leakage caused by severe off-road vibration, keeping your cabin free from diesel fumes and fire hazards. Compact and portable for effortless setup, moving, and storage.
