EcoFlow DELTA Pro 3 vs EcoFlow DELTA mini
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 mini costs $3100 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro 3 holds 364% more energy (4096Wh vs 882Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro 3 has 5900W more surge headroom (8000W vs 2100W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA mini is 89.4 lb lighter (23.6 lb vs 113 lb).
- EcoFlow DELTA Pro 3 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow DELTA Pro 3 is rated for 4,000 cycles vs 800 — meaningful if you cycle it daily.
If you plan to cycle the battery daily, think twice about the EcoFlow DELTA mini. 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 most complete large unit here. 4096Wh, 4000W, 8000W surge and 2600W of solar — it does everything the F3800 does with less weight.
Best for: Whole-home backup buyers who want maximum solar recharge speed.
Where it falls short:
- $3,699 is a serious investment
- Overkill unless you're backing up a whole home
A compact NMC unit with a surprisingly strong 1,400W output for its size — but the 800-cycle battery means it won't age like the LiFePO4 field.
Best for: Buyers who want strong output in a light unit and won’t cycle it daily.
Where it falls short:
- NMC — ~800 cycles
- 2-year warranty, 300W solar input
