CTECHI GT-F300D2 300W 2009.6Wh Portable Power Station — Days of Power, Not Hours

When the mission demands endurance over peak wattage, the CTECHI GT-F300D2 answers the call. By doubling the battery capacity to a massive 2009.6Wh (2kWh) while maintaining a reliable 300W output, this model is purpose-built for scenarios where recharging opportunities are scarce but power must never stop. Think rural off-grid homes, remote field research stations, multi-day disaster relief operations, and long-haul RV journeys. The GT-F300D2 gives you the energy runway to keep essential devices running not for hours, but for days.

Product Advantages

Best 300W 2009.6Wh 2kWh Ultra-Long Endurance Portable Power Station CTECHI LiFePO4 Battery Factory 12

Massive 2009.6Wh Energy Reservoir — 2kWh of Freedom

The GT-F300D2 holds enough energy to power a 10W LED light for 180 hours, a 40W Starlink terminal for 45 hours, or a 60W CPAP machine for 4-5 full nights of uninterrupted sleep. This is the power station for people who cannot afford to run out — rural residents, disaster preparedness planners, and anyone living beyond the reach of reliable grid power.

Same 3-in-1 Architecture, Double the Capacity

Building on the proven GT-F300D platform, the "D2" designation signifies a dual-capacity upgrade — the same efficient 300W pure sine wave inverter, the same integrated MPPT solar controller, but now feeding from a 2kWh battery bank. All the simplicity and reliability of the 3-in-1 design, amplified for users who prioritize runtime above all else.

Built for Continuous Duty Cycles

The reinforced 19kg chassis is engineered to safely house and thermally manage the double-capacity battery pack. An intelligent active cooling system maintains optimal internal temperatures even during extended discharge cycles, ensuring that the 6,000-cycle LFP cells deliver their full rated lifespan regardless of ambient conditions. This is not a consumer gadget — it is a durable energy appliance.

300W Solar Recharging for True Off-Grid Independence

The integrated MPPT solar controller accepts up to 300W of solar input via the 11-55Vdc port, enabling a full solar recharge of the 2kWh bank in approximately 7-8 hours of peak sunlight. Pair with CTECHI solar panels and create a self-sustaining energy ecosystem that keeps your cabin, RV, or remote workstation powered indefinitely without a single drop of fuel.

Smart LCD with Extended Monitoring

The high-definition LCD provides granular insight into your energy status — remaining watt-hours, real-time charge/discharge wattage, estimated runtime at current load, and battery health indicators. When managing a 2kWh energy budget over multiple days, this level of visibility transforms guesswork into confident energy planning.

Product Informations

Introducing the CTECHI GT-F300D2 Ultra-Long Endurance Portable Power Station — the definitive solution for extended off-grid energy requirements. Where standard 1kWh power stations require daily recharging, the GT-F300D2 stretches the interval to 2-4 days for typical low-to-medium loads. This fundamentally changes the user experience for rural homeowners relying on solar, campers exploring remote wilderness, and businesses operating at sites without grid access.

The advanced LiFePO4 battery platform at the heart of the GT-F300D2 is rated for 6,000 cycles at 80% depth of discharge — equivalent to over 16 years of daily cycling. Combined with the integrated pure sine wave inverter and MPPT charge controller, every component is optimized for reliability over flashy peak specs. This is practical, no-nonsense energy storage engineered for the real world.

As a factory-direct CTECHI product with 21 years of battery manufacturing heritage and three ISO/UL-certified production bases, the GT-F300D2 is available for OEM, ODM, and SKD partnerships. Customize the branding, output configuration, and packaging to meet your regional market requirements, with flexible MOQs starting at 10 units. Whether you are a distributor targeting the solar-off-grid market or an e-commerce brand seeking a differentiated long-endurance SKU, the GT-F300D2 offers a compelling value proposition.
