Bluetti AC70 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 AC70 costs $500 less. Whether that gap is worth closing depends on what you need to run.
- Ampace Andes 1500 holds 90% more energy (1462Wh vs 768Wh), so it runs the same load proportionally longer.
- Ampace Andes 1500 has 1600W more surge headroom (3600W vs 2000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti AC70 is 14.8 lb lighter (22 lb vs 36.8 lb).
Bluetti AC70
768Wh with 1000W output at $499 — it does what the EcoFlow River 2 Pro does, with more output and more weight.
Best for: Campers who need to run a small fridge, not just charge devices.
Where it falls short:
- 22 lb — 5 lb heavier than the River 2 Pro
- 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
