Fossibot F2400 vs Mango Power E
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 $2100 less. Whether that gap is worth closing depends on what you need to run.
- Mango Power E holds 73% more energy (3533Wh vs 2048Wh), so it runs the same load proportionally longer.
- Mango Power E has 1200W more surge headroom (6000W vs 4800W) — that decides whether a fridge, pump or AC compressor will actually start.
- Fossibot F2400 is 24.6 lb lighter (48.5 lb vs 73.1 lb).
- Fossibot F2400 is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
The Mango Power E is poor value on paper: 1.18 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.
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
A polished 3.5kWh home unit with a standout 10-year warranty. The catch is a relatively low 660W solar input for the capacity.
Best for: Home-backup buyers who want a long warranty and lots of capacity.
Where it falls short:
- 660W solar input is low for 3.5kWh
- 73.1 lb
