The CTECHI GT-F300D2 is specifically engineered for Fast Charging Endurance scenarios. By pairing a 300W high-efficiency inverter with a massive 2009.6Wh (2kWh) battery bank, this model provides an unprecedented runtime for essential low-wattage devices. It is the ultimate choice for rural living, extended off-grid stays, or multi-day emergency backup where recharging opportunities are scarce. Designed with our safe LFP cell technology and a smart LCD monitoring system, the GT-F300D2 ensures you have days of reliable power at your fingertips.
The GT-F300D2 sets a new standard for runtime. With 2009.6Wh of capacity, it can power a 10W LED light for nearly 180 hours or a 40W satellite internet terminal (like Starlink) for up to 45 hours. This massive capacity-to-power ratio makes it uniquely suited for disaster relief, remote field research, and off-grid living where "energy duration" is more critical than "peak wattage."
Weighing 19kg, the GT-F300D2 features a reinforced chassis designed to handle the weight of the double-capacity battery packs securely. The integrated active cooling system manages internal temperatures effectively during long discharge cycles, ensuring that the 6000+ cycle life of the LiFePO4 cells is preserved even under continuous use in hot climates.
The 3-in-1 architecture brings professional solar charging to a portable scale. The internal MPPT solar controller accepts up to 300W of solar input, allowing the massive 2kWh bank to be refilled using the sun. This creates a sustainable loop of energy capture and storage, perfect for off-grid cabins or businesses operating in areas with unstable grid infrastructure.
