EcoFlow DELTA 3
The DELTA 3 is a 1,024 Wh, 1,800 W EcoFlow station with six AC outlets, a 12 V car socket and extra-battery support up to 5,000 Wh. It suits you if you want one station for camping now and longer outages later.

1,024Wh
1,800 WAC output, 3,600 W peak
840 Whusable at 82%
27.6 lbweight
56 min to fullwall recharge
A CPAP for several nights, a 12 V cooler for a weekend, a refrigerator for most of a day.
Strengths
- Six AC outlets with 1,800 W continuous and 3,600 W surge: starts a 1/2 HP sump pump (2,645 W start-up) and runs it about 54 minutes.
- Expands to 5,000 Wh with DELTA 3 or DELTA Pro 3 extra batteries; the Anker SOLIX C1000 Gen 2 does not take one (DELTA 3 vs SOLIX C1000 Gen 2).
- Full wall recharge in 56 minutes at 1,500 W.
- 12 V car socket (126 W): runs a Dometic CFX3 35 cooler about 3.0 days, or a Starlink Mini about 21 hours.
- Rated for 4,000 cycles to 80+% capacity, with a 5-year warranty.
Limits
- 1,800 W continuous, below the 2,000 W of the Anker SOLIX C1000 Gen 2 and 2,400 W of the DJI Power 1000 V2: a 1,875 W hair dryer is too much.
- 27.6 lb, heavier than the Anker SOLIX C1000 Gen 2 (24.9 lb) and Jackery Explorer 1000 v2 (23.8 lb).
- 500 W solar input and 100 W USB-C ports; the DELTA 3 Plus has 1,000 W and 140 W (DELTA 3 vs DELTA 3 Plus).
- On its own battery it runs a 21 cu ft top-freezer refrigerator about 14 hours, so keeping that refrigerator on for a full day needs an extra battery or a recharge.

EcoFlow DELTA 3 questions
How many nights will the EcoFlow DELTA 3 run a CPAP?
A ResMed AirSense 11 at its typical 56 W runs about 12 hours on AC power: 1.5 nights of 8 hours. ResMed's typical figure includes its humidifier; a higher humidifier or heated-tube setting raises the draw. Running the CPAP from the 12 V socket with ResMed's DC converter avoids the inverter's own draw.
How long does the EcoFlow DELTA 3 take to charge?
EcoFlow states 56 min to full from a wall outlet, and up to 500 W of solar input.
Can you add batteries to the EcoFlow DELTA 3?
Yes. EcoFlow states it expands to 5,000 Wh with its extra batteries.
What battery does the EcoFlow DELTA 3 use?
LiFePO4, rated by EcoFlow for 4000 cycles to 80+% capacity.
