EcoFlow RIVER 2 Pro vs Fossibot F2400
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 $300 less. Whether that gap is worth closing depends on what you need to run.
- Fossibot F2400 holds 167% more energy (2048Wh vs 768Wh), so it runs the same load proportionally longer.
- Fossibot F2400 has 3200W more surge headroom (4800W vs 1600W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 2 Pro is 31.5 lb lighter (17 lb vs 48.5 lb).
- Fossibot F2400 is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
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
A value-brand 2kWh that undercuts the majors sharply while matching them on the specs that matter — 2,400W output and a strong 4,800W surge.
Best for: Bargain hunters who want high surge and 2kWh for the least money.
Where it falls short:
- 500W solar input is low for 2kWh
- Support network trails the majors
