EcoFlow DELTA 3 Ultra vs Zendure SuperBase Pro 2000
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
Zendure SuperBase Pro 2000 costs $200 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Ultra holds 47% more energy (3072Wh vs 2096Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Ultra has 4200W more surge headroom (7200W vs 3000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Zendure SuperBase Pro 2000 is 36.0 lb lighter (47.8 lb vs 83.8 lb).
- EcoFlow DELTA 3 Ultra uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow DELTA 3 Ultra is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
If you plan to cycle the battery daily, think twice about the Zendure SuperBase Pro 2000. Its NMC cells are rated for 3,000 cycles against the LiFePO4 rival's longer life — over years of regular use that's the more expensive unit, whatever the sticker says.
3kWh with 7200W surge at $1799 — this is whole-home territory at a mid-range price. The catch is the 800W solar input.
Best for: Grid-tied home backup where you recharge from the wall, not the sun.
Where it falls short:
- 800W solar input is low for 3kWh — slow off-grid refills
- 83.8 lb
A design-forward 2kWh with a built-in cart, 4G and GPS — feature-rich, but its NMC cells mean fewer cycles than the LiFePO4 field now around it.
Best for: Buyers who value portability features and design over maximum cycle life.
Where it falls short:
- NMC chemistry — fewer cycles than LiFePO4 rivals
- 3,000W surge is modest for the price
