Our verdict
The original DELTA that put EcoFlow on the map. Fast-charging and high-surge for its day, but the NMC battery and lack of USB-C now show its age.
Best for: Bargain hunters who find it heavily discounted.
What we like
- 1,260Wh with a 3,300W surge
- Fast AC charging
Where it falls short
- NMC — ~800 cycles
- No USB-C PD
- 2-year warranty
