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.
- Anker 757 PowerHouse holds 16% more energy (1229Wh vs 1056Wh), so it runs the same load proportionally longer.
- Anker SOLIX C1000 is 15.5 lb lighter (28.44 lb vs 43.9 lb).
We'd skip the Anker SOLIX C1000 in this matchup. It costs $0 more than the Anker 757 PowerHouse 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
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
