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.
- Ampace Andes 1500 holds 2% more energy (1462Wh vs 1440Wh), 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 0.2 lb lighter (36.8 lb vs 37 lb).
- Bluetti AC180P is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
Bluetti AC180P
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
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
