EcoFlow DELTA Pro 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
Mango Power E costs $200 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro holds 2% more energy (3600Wh vs 3533Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro has 1200W more surge headroom (7200W vs 6000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Mango Power E is 25.9 lb lighter (73.1 lb vs 99 lb).
- EcoFlow DELTA Pro is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
EcoFlow DELTA Pro
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
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
