Bluetti AC180 vs EcoFlow DELTA 3 Max Plus
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 $500 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Max Plus holds 78% more energy (2048Wh vs 1152Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Max Plus has 3300W more surge headroom (6000W vs 2700W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti AC180 is 19.9 lb lighter (37.4 lb vs 57.3 lb).
- EcoFlow DELTA 3 Max Plus is rated for 4,000 cycles vs 3,500 — meaningful if you cycle it daily.
Bluetti AC180
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
EcoFlow DELTA 3 Max Plus
Adds 600W of continuous output and doubles surge headroom over the standard Max, for $200. Worth it only if you're running heavy loads.
Best for: Workshops and job sites where tool startup surge is the constraint.
Where it falls short:
- $200 premium is wasted if your loads are under 2400W
- 57 lb
