The EcoFlow DELTA 3 1500 Power Station is a portable power station that combines high capacity, compact design, and intelligent management system. With a nominal capacity of 1,536 Wh, it offers significant power reserves while maintaining a compact size: 400 × 212 × 282 mm (base unit) and a maximum net weight of 16.5 kg.
Equipped with a total of 13 outputs, 4 standard AC outputs (1,800 W nominal, 3,600 W peak) and X-Boost technology that allows you to power devices up to 2,400 W. USB-A and USB-C ports provide fast charging up to 100 W for modern digital devices.
There is also a car output (12.6 V, 10 A) and two DC5521 ports for direct current loads. Charging the DELTA 3 1500 is flexible thanks to 5 modes: from the AC mains (1,500 W in approximately 1.5 hours), from solar panels (input up to 500 W, approximately 3.5 hours), from a compatible smart generator, from a car socket and in hybrid AC+PV mode.
The system uses LiFePO₄ (LFP) cells, with an estimated life cycle of 3,000 cycles, up to 70% of capacity. The battery pack is IP54 certified, offering protective features against dust and water splashes. In UPS mode, switching to battery mode takes less than 15 ms, safeguarding sensitive devices.
The noise generated is low: below 35 dB for loads up to 600 W and below 45 dB up to 1,200 W. Finally, the solution can be managed via an app that allows monitoring, programming and remote control.
The most notable features are:
- Expandable capacity up to 5.5 kWh: allows you to extend the autonomy by connecting compatible modules.
- X'Boost technology: allows you to power devices up to 2,400 W even when starting from a nominal 1,800 W.
- Multi-charging modes (5 modes): includes AC, solar, car, generator and combined AC+PV.
- LiFePO₄ chemistry with 3,000 cycles: ensures long battery life.
- App management + fast UPS (< 15 ms): offers remote control and continuity during blackouts.
