EcoFlow RIVER 2 Pro 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 2 Pro costs $900 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX F2600 holds 233% more energy (2560Wh vs 768Wh), so it runs the same load proportionally longer.
- Anker SOLIX F2600 has 1200W more surge headroom (2800W vs 1600W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 2 Pro is 44.7 lb lighter (17 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.
The one you actually carry. At 17 lb it is light enough for one hand, yet unlike the true pocket units it has the 800W of output needed to run small appliances rather than just charge devices.
Best for: Backpackers, photographers and festival-goers who care about weight above all.
Where it falls short:
- 800W output limits you to electronics and small loads
- 220W solar input means slow off-grid top-ups
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
