EcoFlow DELTA 3 Ultra Portable Power Station

The EcoFlow DELTA 3 Ultra is a high-capacity portable power station built for situations where running extension cable isn’t practical and a gas generator isn’t desirable. With 3,072Wh of battery capacity and 3,600W of continuous AC output, it provides enough power for demanding production equipment while remaining completely portable. It can handle surges up to 7,200W, with EcoFlow’s X-Boost mode supporting certain loads up to 4,600W.

For location production, that makes the DELTA 3 Ultra particularly useful for powering LED fixtures, camera carts, monitors, video village, charging stations, laptops and other production equipment in places where traditional AC power isn’t available. Its pure sine-wave inverter also provides stable AC power suitable for sensitive electronics.

The internal LiFePO4 (LFP) battery is designed for long-term use, while EcoFlow’s battery-management system continuously monitors battery condition and temperature. The DELTA 3 Ultra is also designed to operate quietly, with EcoFlow rating it as low as 25 dB under lighter loads—a major advantage on sets where generator noise can become an issue for production sound.

When it’s time to recharge, the unit supports wall, solar, generator and alternator charging. Standard AC charging provides up to 1,800W input, while the unit also accepts up to 800W of solar input, making it practical for extended remote and off-grid shoots.

With multiple AC outlets, a 30A TT-30 output, USB-C charging up to 140W, USB-A and 12V outputs, the DELTA 3 Ultra can serve as a centralized power source for an entire production setup rather than simply acting as an oversized battery bank.
