Bluetti AC180 vs EcoFlow DELTA Pro
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 $2400 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro holds 213% more energy (3600Wh vs 1152Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro has 4500W more surge headroom (7200W vs 2700W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti AC180 is 61.6 lb lighter (37.4 lb vs 99 lb).
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 Pro
The previous-generation flagship, now mostly worth buying on discount. The Pro 3 beats it on nearly every axis.
Best for: Bargain hunters who find it steeply discounted against the Pro 3.
Where it falls short:
- 99 lb and 165-minute recharge — both beaten by the Pro 3
- Aging platform; expect it to be phased out
