EcoFlow RIVER 3 Plus vs Anker SOLIX F2000
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 $1370 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX F2000 holds 616% more energy (2048Wh vs 286Wh), so it runs the same load proportionally longer.
- Anker SOLIX F2000 has 2400W more surge headroom (3600W vs 1200W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 3 Plus is 38.1 lb lighter (9.9 lb vs 48 lb).
EcoFlow RIVER 3 Plus
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
Anker SOLIX F2000
The older F-series unit, now hard to justify: the C2000 offers the same capacity and surge for $400 less.
Best for: Only worth it if you find it steeply discounted below the C2000.
Where it falls short:
- $1699 is $400 over the newer C2000 with identical core specs
- 105-minute recharge is slow by 2026 standards
