Product Details

The EcoFlow DELTA 3 Max Portable Power Station delivers 2048Wh of LFP capacity with 2400W AC output and up to 500W solar input. Built on LFP battery chemistry with 4,000 cycle longevity, this station is engineered for years of reliable service — whether you need it for heavy-duty backup, RV, or extended off-grid.

For users who need multi-day capacity without stepping up to a 40+ lb unit, this is the target. Two nights of CPAP and full device charging, a full weekend of camping without recharging, or 24 hours of home backup covering a fridge, fans, router, and lights — the 2048Wh capacity comfortably handles all of it.

Available in Gray and Black finishes, the DELTA 3 Max can be expanded with the DELTA 3 Max Plus Extra Battery to double capacity from 2048Wh to 4096Wh — enough for multi-day off-grid power or 24+ hours of essential home backup. The IP65-rated design and 4,000-cycle LFP battery make it equally suited for outdoor deployment and indoor emergency use.
