EcoFlow DELTA 3 Max 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 $500 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Max holds 132% more energy (2048Wh vs 882Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Max has 2700W more surge headroom (4800W vs 2100W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA mini is 31.5 lb lighter (23.6 lb vs 55.1 lb).
- EcoFlow DELTA 3 Max uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow DELTA 3 Max 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 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
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
