Bluetti AC180 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 $200 less. Whether that gap is worth closing depends on what you need to run.
- Bluetti AC180 holds 31% more energy (1152Wh vs 882Wh), so it runs the same load proportionally longer.
- Bluetti AC180 has 600W more surge headroom (2700W vs 2100W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA mini is 13.8 lb lighter (23.6 lb vs 37.4 lb).
- Bluetti AC180 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Bluetti AC180 is rated for 3,500 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.
A solid mid-size unit that competes on price rather than any standout spec. 1152Wh is a useful step above the 1kWh crowd.
Best for: Buyers who catch it on sale and want slightly more than 1kWh.
Where it falls short:
- 37.4 lb is heavy for its capacity
- 2700W surge is mid-pack
- Not expandable
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
