EcoFlow DELTA 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
Fossibot F2400 costs $2300 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro holds 76% more energy (3600Wh vs 2048Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro has 2400W more surge headroom (7200W vs 4800W) — that decides whether a fridge, pump or AC compressor will actually start.
- Fossibot F2400 is 50.5 lb lighter (48.5 lb vs 99 lb).
The EcoFlow DELTA Pro is poor value on paper: 1.13 Wh per dollar versus 2.28 for the Fossibot F2400. Only worth it if you specifically need its higher output or 240V capability — otherwise you're paying a large premium per watt-hour.
The previous-generation flagship, now mostly worth buying on discount. The Pro 3 beats it on nearly every axis.
Best for: Bargain hunters who find it steeply discounted against the Pro 3.
Where it falls short:
- 99 lb and 165-minute recharge — both beaten by the Pro 3
- Aging platform; expect it to be phased out
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
