Bluetti AC180 vs Ampace Andes 1500
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.
- Ampace Andes 1500 holds 27% more energy (1462Wh vs 1152Wh), so it runs the same load proportionally longer.
- Ampace Andes 1500 has 900W more surge headroom (3600W vs 2700W) — that decides whether a fridge, pump or AC compressor will actually start.
- Ampace Andes 1500 is 0.6 lb lighter (36.8 lb vs 37.4 lb).
- Bluetti AC180 is rated for 3,500 cycles vs 3,000 — 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
Ampace Andes 1500
Backed by an Amperex/CATL cell pedigree, the Andes 1500 stands out on charge speed — 0-80% in well under an hour — and a light 36.8 lb for 1.5kWh.
Best for: Buyers who prize fast charging and low weight at 1.5kWh.
Where it falls short:
- Newer brand with a thinner track record
- Not expandable
