Estimated runtimes
These use our planning factor of 0.8 usable energy (for inverter losses and reserve) and the appliance wattages published by Honda and Champion. They assume continuous running, so cycling loads will usually last longer.
- Energy Star refrigerator (192 W running): about 4.3 hours of compressor run time
- CPAP without heated humidifier (60 W): about 14 hours
- 1/3 HP furnace blower (700 W running in Honda's chart): about 1.2 hours of blower run time. Many blowers draw less, so check the nameplate. Furnace guide
Who it's for
The C1000 Gen 2 is a portable 1 kWh unit. Its standouts on paper are 2,000W continuous output (high for its capacity), a 49-minute full recharge at 1,600W, and 24.9 lb weight. That makes it a fit for fridge-plus-electronics backup and for topping up quickly from a generator or a car-charging stop. The trade-off is that it can't be expanded with extra batteries, and Anker's product page doesn't state the cell chemistry, so we list it as not stated.

FAQ
Can you add an extra battery to the Anker SOLIX C1000 Gen 2?
No. Anker says the C1000 Gen 2 has no expansion port, to keep it smaller and lighter, and recommends the original C1000 if you need expandable capacity.
How fast does the C1000 Gen 2 recharge?
Anker quotes a full recharge in 49 minutes at 1,600W in UltraFast mode (enabled in the Anker app), or about 1.8 hours from 600W of solar. Anker's FAQ notes UltraFast only kicks in when the battery is above 68°F (20°C), so expect slower charging in a cold room.
Will it work as a UPS for a CPAP or router?
Anker lists a UPS switchover under 10 ms. Check your device maker's guidance on UPS use, especially for medical equipment.
