The full specification
Every figure below is read from the maker's own specification page. Where a value is missing, it is missing because Anker SOLIX does not publish it, not because it was too much trouble to find.

Where it is strong, and where it is not
- Backup switchover. On this axis it switches over fast enough to carry a computer through a cut.
What it will actually run
These estimates use the same arithmetic as the run time calculator: usable watt hours after an assumed 85% inverter efficiency, divided by the appliance's average draw rather than its peak. The fridge figure assumes the compressor runs about a third of the time, which is what makes it plausible.
| Appliance | Typical draw | Estimated run time |
|---|---|---|
| Fridge | 120 W | 21 h 22 min |
| CPAP machine | 45 W | 19 h 57 min |
| Router and modem | 15 W | 59 h 50 min |
| Television | 90 W | 9 h 58 min |
| Microwave | 1200 W | 0 h 45 min |

Common questions
How long will the C1000 run a fridge?
See the table above. The figure assumes an average domestic fridge and a compressor running about a third of the time. A warm room, a full shelf of fresh shopping or a door that keeps opening all push the real duty cycle up and the run time down.
Can I add capacity later?
Yes, this model accepts an expansion battery. That matters more than it looks: most people underestimate the size they need, and an expandable unit turns that mistake into an accessory purchase rather than a replacement.
What does the cycle rating promise?
That after 3,000 cycles to 80%, the pack still holds the stated share of its original capacity. It is a degradation threshold, not a failure point. Always note the endpoint when comparing against another maker: they do not all quote the same one.
