EcoFlow DELTA 2 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
These two cost the same, so the decision comes down to what you're powering.
- Fossibot F2400 holds 100% more energy (2048Wh vs 1024Wh), so it runs the same load proportionally longer.
- Fossibot F2400 has 2600W more surge headroom (4800W vs 2200W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 2 is 21.5 lb lighter (27 lb vs 48.5 lb).
- Fossibot F2400 is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
We'd skip the EcoFlow DELTA 2 in this matchup. It costs $0 more than the Fossibot F2400 while matching or trailing it on capacity, surge and cycle life — there's no spec here that justifies the premium.
The value pick in the 1kWh class. Cheaper than the Anker C1000 with nearly identical capacity — but check the surge number before you buy.
Best for: Budget-conscious buyers running electronics and a fridge, with no motor-driven loads.
Where it falls short:
- X-Boost tops out at 2200W — the least surge headroom of any 1kWh unit we list
- 80-minute recharge is slower than Anker's 58
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
