EcoFlow DELTA 3 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 DELTA 3 costs $150 less. Whether that gap is worth closing depends on what you need to run.
- Segway Cube 1000 has 800W more surge headroom (4400W vs 3600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Segway Cube 1000 is 0.3 lb lighter (28.4 lb vs 28.7 lb).
- EcoFlow DELTA 3 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
EcoFlow DELTA 3
The 1kWh class got a serious upgrade here. 3600W surge at $649 beats the older DELTA 2 on every axis that matters.
Best for: Anyone about to buy a DELTA 2 — this is the same money for materially better specs.
Where it falls short:
- Still only 1024Wh
- Solar input unchanged at 500W
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
