EcoFlow RIVER 2 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
EcoFlow RIVER 2 Pro costs $2400 less. Whether that gap is worth closing depends on what you need to run.
- Mango Power E holds 360% more energy (3533Wh vs 768Wh), so it runs the same load proportionally longer.
- Mango Power E has 4400W more surge headroom (6000W vs 1600W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 2 Pro is 56.1 lb lighter (17 lb vs 73.1 lb).
The one you actually carry. At 17 lb it is light enough for one hand, yet unlike the true pocket units it has the 800W of output needed to run small appliances rather than just charge devices.
Best for: Backpackers, photographers and festival-goers who care about weight above all.
Where it falls short:
- 800W output limits you to electronics and small loads
- 220W solar input means slow off-grid top-ups
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
