Home or away, you can provide power to major appliances and infrastructure using the EcoFlow DELTA Pro 3 Portable Battery Generator. Equipped with automotive-grade LFP power cells, the DELTA Pro 3 has 4096Wh of capacity and a maximum output up to 4000W (8000W surge). This is enough to run everything from stoves and refrigerators to central AC units and water pumps. It even has a dedicated NEMA TT-30R output for powering your RV. You can expand your power options and link up three units in parallel for up to 12,000W of simultaneous output. All this is done safely and quietly thanks to the unit's robust construction and EcoFlow's X-Quiet and X-Guard technologies. When in use, managing the unit is easy using the built-in display or from your phone via the EcoFlow mobile app.
