EcoFlow RIVER 3 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
EcoFlow RIVER 3 costs $2760 less. Whether that gap is worth closing depends on what you need to run.
- Mango Power E holds 1342% more energy (3533Wh vs 245Wh), so it runs the same load proportionally longer.
- Mango Power E has 5400W more surge headroom (6000W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 3 is 65.3 lb lighter (7.8 lb vs 73.1 lb).
EcoFlow RIVER 3
A glorified power bank with AC outlets — and that's fine if that's what you need. 245Wh runs devices, not appliances.
Best for: Weekend campers charging phones, cameras and a laptop.
Where it falls short:
- 300W output rules out anything with a heating element
- No expansion path
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
