The numbers
| Battery capacity | 1056Wh (LFP) |
|---|---|
| Usable energy | 898Wh (85% via AC outlets) |
| Continuous AC output | 1800W |
| Surge rating | 2400W |
| Space heater running watts | 1500W |
| Startup watts | 1500W |
| Average draw | 1500W |
| Estimated runtime | 36 minutes |
| Energy per day of typical use | 12 kWh |
1056Wh × 0.85 = 898Wh usable ÷ 1500W average = 0.6 hours

Recharging with solar
The Anker SOLIX C1000 accepts up to 600W of solar input. In real conditions that harvests about 2.3 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.
Solar can’t fully keep up. A space heater uses about 12 kWh a day at 8 hours of use, more than the Anker SOLIX C1000’s best-case solar harvest. Solar will stretch the runtime but not sustain it.
Tips
- Space heaters are the hardest load for a battery: 1,500W of continuous heat. The low setting (usually 750W) doubles runtime.
- You’ll still have about 300W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The Anker SOLIX C1000 uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.

FAQ
Will the Anker SOLIX C1000 run a space heater overnight?
No. At about 1500W average it runs out after 36 minutes. For a full night you need at least 14200Wh of capacity.
How long does the Anker SOLIX C1000 take to recharge with solar?
With its maximum 600W of solar input it refills in about 2.3 hours of strong sun. With a single 200W panel, expect about 7 hours of full sun.
