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 DELTA 3 Ultra costs $1200 less. Whether that gap is worth closing depends on what you need to run.
- Mango Power E holds 15% more energy (3533Wh vs 3072Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Ultra has 1200W more surge headroom (7200W vs 6000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Mango Power E is 10.7 lb lighter (73.1 lb vs 83.8 lb).
- EcoFlow DELTA 3 Ultra is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
EcoFlow DELTA 3 Ultra
3kWh with 7200W surge at $1799 — this is whole-home territory at a mid-range price. The catch is the 800W solar input.
Best for: Grid-tied home backup where you recharge from the wall, not the sun.
Where it falls short:
- 800W solar input is low for 3kWh — slow off-grid refills
- 83.8 lb
Mango Power E
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
