EcoFlow RIVER 3 vs EcoFlow DELTA 1300
Side-by-side on the specs that decide it — surge, capacity, runtime and price.
Both models' specs verified against manufacturer listings · Last updated
The short answer
EcoFlow RIVER 3 costs $760 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 1300 holds 414% more energy (1260Wh vs 245Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 1300 has 2700W more surge headroom (3300W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 3 is 23.1 lb lighter (7.8 lb vs 30.9 lb).
- EcoFlow RIVER 3 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow RIVER 3 is rated for 3,000 cycles vs 800 — meaningful if you cycle it daily.
If you plan to cycle the battery daily, think twice about the EcoFlow DELTA 1300. Its NMC cells are rated for 800 cycles against the LiFePO4 rival's longer life — over years of regular use that's the more expensive unit, whatever the sticker says.
A glorified power bank with AC outlets — and that's fine if that's what you need. 245Wh runs devices, not appliances.
Best for: Weekend campers charging phones, cameras and a laptop.
Where it falls short:
- 300W output rules out anything with a heating element
- No expansion path
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.
Where it falls short:
- NMC — ~800 cycles
- No USB-C PD
- 2-year warranty
