EcoFlow DELTA 2 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 $200 less. Whether that gap is worth closing depends on what you need to run.
- Bluetti AC180P holds 41% more energy (1440Wh vs 1024Wh), so it runs the same load proportionally longer.
- Bluetti AC180P has 500W more surge headroom (2700W vs 2200W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 2 is 10.0 lb lighter (27 lb vs 37 lb).
- Bluetti AC180P is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
We'd skip the EcoFlow DELTA 2 in this matchup. It costs $200 more than the Bluetti AC180P while matching or trailing it on capacity, surge and cycle life — there's no spec here that justifies the premium.
The value pick in the 1kWh class. Cheaper than the Anker C1000 with nearly identical capacity — but check the surge number before you buy.
Best for: Budget-conscious buyers running electronics and a fridge, with no motor-driven loads.
Where it falls short:
- X-Boost tops out at 2200W — the least surge headroom of any 1kWh unit we list
- 80-minute recharge is slower than Anker's 58
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
