Quick take: Anker SOLIX C1000 Gen 2 is a compact 1kWh-class portable power station with 1,024Wh capacity, 2,000W continuous AC output, 3,000W peak output, up to 600W solar input and sub-10ms UPS switching according to Anker. It is a different generation from the original 1,056Wh / 1,800W C1000.
Editorial note: This is a specification-based buying guide, not a hands-on review. Specifications were checked against Anker’s official product information in September 2026.
Anker SOLIX C1000 Gen 2 key specs
- Battery capacity: 1,024Wh
- Continuous AC output: 2,000W
- Peak output: 3,000W
- Solar input: up to 600W
- UPS: automatic switching under 10ms
- Battery-life claim: at least 80% capacity after 4,000 cycles under Anker’s stated conditions
That specification set places the C1000 Gen 2 in the compact 1kWh class for refrigerator backup, CPAP, electronics, camping and selected short-duration household loads. Runtime still depends on actual load, inverter losses and battery state.
Do not confuse it with the original C1000. The earlier model uses a 1,056Wh battery and 1,800W inverter, while the Gen 2 moves to 1,024Wh and 2,000W continuous output.

Before buying
Estimate both running watts and startup surge for the appliances you intend to power. For refrigerators and other cycling loads, battery capacity alone does not determine compatibility. Start with the Backup Power Map and our refrigerator battery-backup guide.
