EcoFlow RIVER 3 Plus vs Anker SOLIX F2600
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 $1170 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX F2600 holds 795% more energy (2560Wh vs 286Wh), so it runs the same load proportionally longer.
- Anker SOLIX F2600 has 1600W more surge headroom (2800W vs 1200W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 3 Plus is 51.8 lb lighter (9.9 lb vs 61.7 lb).
- Anker SOLIX F2600 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
Neither of these will start a sump pump or well pump — both surge below the ~3,400W those motors need. If home backup with pumps is your use case, look at higher-surge models instead of either of these.
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
An odd spec sheet: 2560Wh of capacity but only 2800W surge — the lowest surge-to-capacity ratio here. Capacity without starting power.
Best for: Long-duration backup of steady loads (lights, electronics, CPAP) rather than motor-driven appliances.
Where it falls short:
- 2800W surge is barely above its 2400W continuous — it will struggle with pumps
- 61.7 lb
