Bluetti AC180 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 AC180 costs $200 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 1300 holds 9% more energy (1260Wh vs 1152Wh), 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 6.5 lb lighter (30.9 lb vs 37.4 lb).
- Bluetti AC180 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Bluetti AC180 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 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
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
