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
Bluetti EB3A costs $660 less. Whether that gap is worth closing depends on what you need to run.
- Fossibot F2400 holds 664% more energy (2048Wh vs 268Wh), so it runs the same load proportionally longer.
- Fossibot F2400 has 3600W more surge headroom (4800W vs 1200W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti EB3A is 38.4 lb lighter (10.1 lb vs 48.5 lb).
- Fossibot F2400 is rated for 3,500 cycles vs 2,500 — meaningful if you cycle it daily.

- 268Wh empties fast under real load
Fossibot F2400
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
