Anker SOLIX C1000 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 38% more energy (1462Wh vs 1056Wh), 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.
- Anker SOLIX C1000 is 8.4 lb lighter (28.44 lb vs 36.8 lb).
We'd skip the Anker SOLIX C1000 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.
The default recommendation for most people. It clears the 1kWh bar, recharges in under an hour, and undercuts almost everything with comparable specs.
Best for: First-time buyers who want one unit for camping and short outages without overpaying.
Where it falls short:
- 2400W surge won't start a sump pump or well pump
- Only 1056Wh — a fridge-plus-devices outage tops out around a day
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
