EcoFlow DELTA Max 2000 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 Max 2000 holds 97% more energy (2016Wh vs 1024Wh), so it runs the same load proportionally longer.
- Segway Cube 1000 has 1000W more surge headroom (4400W vs 3400W) — that decides whether a fridge, pump or AC compressor will actually start.
- Segway Cube 1000 is 19.6 lb lighter (28.4 lb vs 48 lb).
- Segway Cube 1000 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Segway Cube 1000 is rated for 3,000 cycles vs 800 — meaningful if you cycle it daily.
If you plan to cycle the battery daily, think twice about the EcoFlow DELTA Max 2000. Its NMC cells are rated for 800 cycles against the LiFePO4 rival's longer life — over years of regular use that's the more expensive unit, whatever the sticker says.
The previous-generation 2kWh EcoFlow. Still capable and expandable, but its NMC cells and 800-cycle rating are a real step below the LiFePO4 DELTA 3 that replaced it.
Best for: Only at a steep discount against the DELTA 3 Max.
Where it falls short:
- NMC — roughly 800 cycles vs 4,000 for the DELTA 3 Max
- 2-year warranty
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
