Strengths
- Full AC recharge in 56 minutes at 1500W input
- Expandable up to 5kWh with DELTA 3, DELTA 2, DELTA 2 Max or DELTA Pro 3 extra batteries
- 13 outputs including six AC outlets and a 126W car outlet
- LiFePO4 battery rated for 4,000 cycles to 80% capacity
Watch out for
- Single 500W solar input (the DELTA 3 Plus doubles it to 1000W)
- USB-C ports are capped at 100W and USB-A at 18W
- 27.6 lb with no wheels
- The 800 W car-charging figure assumes EcoFlow's 800W Alternator Charger; a standard 12V car socket supplies far less

Runtime = usable energy ÷ average draw. We count 85% of the rated 1,024 Wh as usable (870 Wh) to cover inverter and DC conversion losses. Fridges and freezers are averaged over their compressor cycle. An appliance runs only if its running watts fit the 1,800 W inverter and its start-up surge fits the 3,600 W surge rating. Wattages come from our appliance wattage table; try your own mix in the runtime calculator.
Which solar panels fit it?
- Solar input up to 500 W
- Voltage window 11–60 V
- Connector XT60i
Recharge time is from empty with one panel in full sun: 1,024 Wh ÷ the lower of75% of the panel's rating or the station's solar input limit. A panel rated above the input limit is safe as long as its Voc fits, because the station only draws what it can take. MC4 panels need a standard MC4 adapter cable, which many stations include. Wiring two panels in series doubles the Voc, so check the total against the voltage window. Try any pairing in the solar panel matcher.
