Bluetti AC180P vs EcoFlow DELTA 1300
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 $300 less. Whether that gap is worth closing depends on what you need to run.
- Bluetti AC180P holds 14% more energy (1440Wh vs 1260Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 1300 has 600W more surge headroom (3300W vs 2700W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 1300 is 6.1 lb lighter (30.9 lb vs 37 lb).
- Bluetti AC180P uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Bluetti AC180P is rated for 3,500 cycles vs 800 — meaningful if you cycle it daily.
If you plan to cycle the battery daily, think twice about the EcoFlow DELTA 1300. Its NMC cells are rated for 800 cycles against the LiFePO4 rival's longer life — over years of regular use that's the more expensive unit, whatever the sticker says.
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
The original DELTA that put EcoFlow on the map. Fast-charging and high-surge for its day, but the NMC battery and lack of USB-C now show its age.
Best for: Bargain hunters who find it heavily discounted.
Where it falls short:
- NMC — ~800 cycles
- No USB-C PD
- 2-year warranty
