Bluetti AC2A 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 AC2A costs $800 less. Whether that gap is worth closing depends on what you need to run.
- Ampace Andes 1500 holds 617% more energy (1462Wh vs 204Wh), so it runs the same load proportionally longer.
- Ampace Andes 1500 has 3000W more surge headroom (3600W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti AC2A is 28.9 lb lighter (7.9 lb vs 36.8 lb).
Bluetti AC2A
One of the cheapest LiFePO4 stations on the market. 204Wh is tiny, but a 200W solar input that outpaces the capacity makes it a surprisingly capable little off-grid trickle unit.
Best for: Ultralight campers who recharge from a panel daily.
Where it falls short:
- 204Wh is genuinely small
- 300W output is device-only
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
