EcoFlow DELTA Pro 3 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 $3000 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro 3 holds 184% more energy (4096Wh vs 1440Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro 3 has 5300W more surge headroom (8000W vs 2700W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti AC180P is 76.0 lb lighter (37 lb vs 113 lb).
- EcoFlow DELTA Pro 3 is rated for 4,000 cycles vs 3,500 — meaningful if you cycle it daily.
The EcoFlow DELTA Pro 3 is poor value on paper: 1.11 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 most complete large unit here. 4096Wh, 4000W, 8000W surge and 2600W of solar — it does everything the F3800 does with less weight.
Best for: Whole-home backup buyers who want maximum solar recharge speed.
Where it falls short:
- $3,699 is a serious investment
- Overkill unless you're backing up a whole home
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
