Anker SOLIX C1000 Gen 2 Review
A 1 kWh station with 2,000 W of output and very fast wall charging. Right for short outages, a CPAP or a home office; too small to carry a house through the night.
The C1000 Gen 2 is the smallest station on our list and the cheapest at $799 list ($699 seen in late October 2026). It keeps a router, phones, a laptop and a CPAP going through a typical evening outage, and its 2,000 W output can briefly run a microwave or kettle. It is not enough to keep a fridge cold through a long outage, so treat it as a grab-and-go unit rather than whole-home backup.
Who it's for
Buy the C1000 Gen 2 if your outages last a few hours, you need to keep a CPAP, internet or work setup running, or you want a portable unit for camping that doubles as backup.
Skip it if you want to keep a fridge running overnight and still power lights and internet. A 2 kWh station such as the Bluetti Elite 200 V2 is the practical minimum for that.

hours ≈ 1,024 × 0.85 ÷ watts used
- Router and modem (about 20 W): roughly 44 hours.
- CPAP without humidifier (about 40 W): roughly 22 hours, or two to three nights. See CPAP runtime.
- Typical fridge only (about 100 W average): roughly 8.7 hours.
- Fridge, router and LED lights (about 220 W average): roughly 4.0 hours.
Fast charging is its best trick: when a storm is forecast, or when power returns briefly between outages, it refills in under an hour.
