ViperScore breakdown
Should you buy the EcoFlow DELTA 2?
The DELTA 2 is our highest-scoring power station and the one to buy if you want the most capability per dollar in the 1 kWh class. It's for home backup, car camping and anyone who wants room to grow: it can take an extra battery later.
Where it earns its score
- 1,024 Wh LFP, 3,000 cycles. Long-life chemistry at a price that used to buy NMC.
- 1,800 W output, 2,700 W X-Boost. Runs a fridge, a microwave, a space heater, most power tools.
- Six AC outlets and two 100 W USB-C. More ports than anything near its price.
- 0–80% in 50 minutes. Among the fastest AC recharges in the class; 500 W solar input for off-grid.
- Expandable to 2,048 Wh. Add the extra battery instead of replacing the unit.
- 5-year warranty.
What to know first
- 27 lb. Light for the class but not a one-hand carry.
- Fan noise under heavy load. Normal for 1,800 W; noticeable in a tent.
- Check the price. The $599.00 research price is a sale; list is higher.
Our verdict
The DELTA 2 scores 90, a Viper Pick, our top-rated power station. It wins on output, ports, charging speed, expandability and warranty, and the only reason to pick something else is weight (Jackery 1000 v2) or budget (RIVER 2 Pro).

Questions buyers ask
Can the EcoFlow DELTA 2 run a refrigerator?
Yes. A typical full-size fridge draws well under its 1,800 W continuous rating, and X-Boost handles startup surges up to 2,700 W.
How long does the DELTA 2 take to charge?
About 50 minutes to 80% and 80 minutes to full from a wall outlet.
DELTA 2 or Jackery Explorer 1000 v2?
Same capacity. The DELTA 2 has more output, twice the AC outlets, faster charging, expandability and a stronger warranty; the Jackery is 3 lb lighter with a higher cycle rating. We score them 90 and 88.
