EcoFlow RIVER 3 Plus 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 Plus costs $670 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 1300 holds 341% more energy (1260Wh vs 286Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 1300 has 2100W more surge headroom (3300W vs 1200W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 3 Plus is 21.0 lb lighter (9.9 lb vs 30.9 lb).
- EcoFlow RIVER 3 Plus uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow RIVER 3 Plus 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.
Doubles the River 3's output for $90 more, and adds an expansion battery port. The better buy of the two unless weight is everything.
Best for: Campers who want one unit that covers devices plus the occasional small appliance.
Where it falls short:
- 286Wh alone is a single evening of real use
- 220W solar input is modest
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
