EcoFlow DELTA Pro vs Bluetti AC180P
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 AC180P costs $2500 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro holds 150% more energy (3600Wh vs 1440Wh), 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 AC180P is 62.0 lb lighter (37 lb vs 99 lb).
The EcoFlow DELTA Pro is poor value on paper: 1.13 Wh per dollar versus 2.06 for the Bluetti AC180P. Only worth it if you specifically need its higher output or 240V capability — otherwise you're paying a large premium per watt-hour.
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
A higher-capacity take on the AC180, adding 25% more watt-hours for the same 1,800W output — a useful step up if you catch it near the AC180's price.
Best for: Buyers who want more than 1kWh from a mainstream brand on sale.
Where it falls short:
- 37 lb
- 2,700W surge is mid-pack
- Not expandable
