Anker 757 PowerHouse 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
These two cost the same, so the decision comes down to what you're powering.
- Ampace Andes 1500 holds 19% more energy (1462Wh vs 1229Wh), so it runs the same load proportionally longer.
- Ampace Andes 1500 has 1200W more surge headroom (3600W vs 2400W) — that decides whether a fridge, pump or AC compressor will actually start.
- Ampace Andes 1500 is 7.1 lb lighter (36.8 lb vs 43.9 lb).
We'd skip the Anker 757 PowerHouse in this matchup. It costs $0 more than the Ampace Andes 1500 while matching or trailing it on capacity, surge and cycle life — there's no spec here that justifies the premium.
Anker's older flagship, now a discount play. Solid and durable, but heavy for its capacity and outclassed on charge speed by the newer C-series.
Best for: Buyers who find it discounted below the newer Anker C1000.
Where it falls short:
- 43.9 lb for 1.2kWh is heavy
- 300W solar input is low
- Outclassed by the newer C1000
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
