Anker SOLIX C800 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
Anker SOLIX C800 costs $400 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 2000W more surge headroom (3600W vs 1600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker SOLIX C800 is 11.9 lb lighter (24.9 lb vs 36.8 lb).
Anker SOLIX C800
The C1000's smaller sibling. Same fast-charging DNA at a lower price, but the 768Wh capacity puts it firmly in weekend-trip territory.
Best for: Campers and van-lifers powering electronics, lights and a mini fridge — not home backup.
Where it falls short:
- 300W solar input is low — slow to top off off-grid
- 1600W surge rules out most motor-driven appliances
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
