EcoFlow DELTA 3 Max 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
Segway Cube 1000 costs $300 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Max holds 100% more energy (2048Wh vs 1024Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Max has 400W more surge headroom (4800W vs 4400W) — that decides whether a fridge, pump or AC compressor will actually start.
- Segway Cube 1000 is 26.7 lb lighter (28.4 lb vs 55.1 lb).
- EcoFlow DELTA 3 Max is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
EcoFlow DELTA 3 Max
The value leader in the 2kWh class. Same 4800W surge as the DELTA 2 Max at $500 less, with 1000 more cycles.
Best for: Home backup buyers who want compressor-starting surge without paying flagship prices.
Where it falls short:
- 55 lb is a two-hand lift
- Only marginally lighter than heavier rivals
Segway Cube 1000
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
