EcoFlow RIVER 2 Pro vs Segway Cube 1000
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 $200 less. Whether that gap is worth closing depends on what you need to run.
- Segway Cube 1000 holds 33% more energy (1024Wh vs 768Wh), so it runs the same load proportionally longer.
- Segway Cube 1000 has 2800W more surge headroom (4400W vs 1600W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 2 Pro is 11.4 lb lighter (17 lb vs 28.4 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
Segway's stackable home unit brings a strong 2,200W output at 1kWh and a modular design, though the cube form factor is bulkier than flat rivals.
Best for: Buyers who want a stackable, expandable home system starting at 1kWh.
Where it falls short:
- Bulky cube shape
- 3-year warranty
