Bluetti AC180 vs EcoFlow DELTA 3 Plus
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
EcoFlow DELTA 3 Plus costs $50 less. Whether that gap is worth closing depends on what you need to run.
- Bluetti AC180 holds 13% more energy (1152Wh vs 1024Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Plus has 900W more surge headroom (3600W vs 2700W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 3 Plus is 8.7 lb lighter (28.7 lb vs 37.4 lb).
- EcoFlow DELTA 3 Plus is rated for 4,000 cycles vs 3,500 — meaningful if you cycle it daily.
Bluetti AC180
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
EcoFlow DELTA 3 Plus
The DELTA 3 with a $100 premium for smart-home integration and faster UPS switching. Same battery, same surge.
Best for: Home-office setups where a desktop or NAS can't tolerate a power blip.
Where it falls short:
- $100 more for features many buyers never use
- Same 1024Wh as the cheaper DELTA 3
