The numbers
| Battery capacity | 768Wh (LFP) |
|---|---|
| Usable energy | 653Wh (85% via AC outlets) |
| Continuous AC output | 1200W |
| Surge rating | 1600W |
| Window AC (8,000 BTU) running watts | 700W |
| Startup watts | 2000W |
| Average draw | 490W |
| Estimated runtime | 1.3 hours |
| Energy per day of typical use | 3.9 kWh |
768Wh × 0.85 = 653Wh usable ÷ 490W average = 1.3 hours

Recharging with solar
The Anker SOLIX C800 Plus accepts up to 300W of solar input. In real conditions that harvests about 1.1 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.
Solar can’t fully keep up. A window AC (8,000 BTU) uses about 3.9 kWh a day at 8 hours of use, more than the Anker SOLIX C800 Plus’s best-case solar harvest. Solar will stretch the runtime but not sustain it.
Tips
- Mid-size window units need a stout inverter to survive the compressor start.
- You’ll still have about 500W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The Anker SOLIX C800 Plus uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
