EcoFlow DELTA 3 Plus

Q: How many nights will the EcoFlow DELTA 3 Plus 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.

Q: How long does the EcoFlow DELTA 3 Plus take to charge?

EcoFlow states 56 min to full from a wall outlet, and up to 1,000 W of solar input.

Q: Can you add batteries to the EcoFlow DELTA 3 Plus?

Yes. EcoFlow states it expands to 5,000 Wh with its extra batteries.

Q: What battery does the EcoFlow DELTA 3 Plus use?

LiFePO4, rated by EcoFlow for 4000 cycles to 80+% capacity.

The DELTA 3 Plus is the DELTA 3 with more solar input and higher-rated USB-C ports: the same 1,024 Wh, 1,800 W and 27.6 lb, plus 1,000 W of solar input over two ports and USB-C ports up to 140 W. It suits you if you plan to recharge from solar panels.

1,024Wh

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

1,000 W solar input over two 500 W ports, twice the 500 W of the DELTA 3 and DELTA 3 Classic.
USB-C ports up to 140 W, against 100 W on the DELTA 3.
Six AC outlets, 1,800 W continuous and 3,600 W surge: runs a family-size microwave that draws 1,600 W about 31 minutes.
Expands to 5,000 Wh, and recharges from the wall in 56 minutes at 1,500 W.
EcoFlow rates it for 4,000 cycles to 80+% capacity and gives it a 5-year warranty.

Limits

Battery, AC output and weight match the DELTA 3, so the two run the same loads for the same time; the differences are solar input and USB port power (DELTA 3 vs DELTA 3 Plus).
27.6 lb, heavier than the Anker SOLIX C1000 Gen 2 (24.9 lb), which has 2,000 W of AC output.
1,800 W continuous and 1,000 W solar input, against 2,400 W and 1,800 W on the DJI Power 1000 V2 at the same 1,024 Wh; a 1,875 W hair dryer is too much for the DELTA 3 Plus.
