Bluetti AC180 vs EcoFlow DELTA Max 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
Bluetti AC180 costs $300 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Max 2000 holds 75% more energy (2016Wh vs 1152Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Max 2000 has 700W more surge headroom (3400W vs 2700W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti AC180 is 10.6 lb lighter (37.4 lb vs 48 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 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.
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
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
