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 Plus costs $2670 less. Whether that gap is worth closing depends on what you need to run.
- Mango Power E holds 1135% more energy (3533Wh vs 286Wh), so it runs the same load proportionally longer.
- Mango Power E has 4800W more surge headroom (6000W vs 1200W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 3 Plus is 63.2 lb lighter (9.9 lb vs 73.1 lb).
EcoFlow RIVER 3 Plus
Doubles the River 3's output for $90 more, and adds an expansion battery port. The better buy of the two unless weight is everything.
Best for: Campers who want one unit that covers devices plus the occasional small appliance.
Where it falls short:
- 286Wh alone is a single evening of real use
- 220W solar input is modest
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
