Next-level energy for next-level peace of mind.
EcoFlow DELTA 3 Max Plus (2048Wh) delivers 3000W AC rated output (6000W surge). With X-Boost™ 3.0 technology, it supports devices up to 3800W—effortlessly taking on your heavy-duty appliances. The inverter samples AC voltage and current every 33μs with high precision using a DSP chip, ensuring pure sine wave output with beyond grid-level stability—ideal for powering sensitive electronics reliably.
1800W Input, 0-80% in 64 mins. [4] EcoFlow’s exclusive Storm Guard Mode [5] monitors severe weather alerts and automatically triggers AC charging remotely using industry-leading X-Stream fast charging tech—so it can be ready long before a disaster hits.
Charges at up to 2600W via smart generator—0–80% in 43 minutes. With exclusive Generator Auto Start/Stop Mode, [6] the EcoFlow Smart Generator 4000 (Dual Fuel) recharges DELTA 3 Max Plus (2048Wh) automatically when battery levels run low—delivering hands-free backup power for storms, outages, and off-grid use.
1000W Input, 0-80% in 96 mins*. After the storm clears, just 96 minutes of sunlight is all it takes to recharge DELTA 3 Max Plus (2048Wh). Pair it with EcoFlow 220W Solar Panels (25% high-efficiency) for reliable power during camping trips, van life, or off-grid living. [7]
1000W Input, 0-80% in 95 mins. With the EcoFlow Alternator Charger Plus 1000, [8] get ready in just 95 minutes while on the move—10× faster than conventional solutions. [9]
Go from 0-80% charged in just 51 minutes—dual input from 1000W solar and 1000W alternator charging keeps you powered faster than ever, even on the go.
Rugged exterior and intelligent BMS for unmatched reliability
