Powerful Portable Backup

EcoFlow DELTA 3 Max is a high-capacity portable power station designed for home backup, campervan power, and off-grid electricity where reliable AC output is required.

It combines a 2,048Wh lithium iron phosphate (LFP) battery with a 2,400W AC inverter, delivering strong performance for everyday appliances and tools within its rated limits.

DELTA 3 Max supports multiple charging methods including mains power, solar panels, vehicle charging, and generator input, allowing flexible use at home, on the road, or on site.

The system also includes fast UPS switchover (approx. 10ms) to help maintain power to sensitive electronics during short outages.

Large 2,048Wh LFP Battery

DELTA 3 Max uses LiFePO₄ battery chemistry, designed for long cycle life and stable performance.

Battery capacity: 2,048Wh
Battery type: LiFePO₄ (LFP)
Long cycle life battery technology

This capacity allows the unit to power a wide range of devices during outages or off-grid use.

2,400W AC Output

DELTA 3 Max delivers strong inverter performance suitable for many common appliances.

AC output: 2,400W continuous
Surge output: 4,800W
X-Boost: supports devices up to approx. 3,200W (manufacturer feature)

X-Boost can allow certain higher-wattage devices to operate by adjusting output characteristics.

Fast Charging Technology
