| Usable energy | 245Wh (85% via AC outlets) |
| Continuous AC output | 300W |
| Surge rating | 600W |
| String lights running watts | 20W |
| Startup watts | 20W |
| Average draw | 20W |
| Estimated runtime | 12 hours |
| Energy per day of typical use | 100Wh |
288Wh × 0.85 = 245Wh usable ÷ 20W average = 12.2 hours

Recharging with solar
The Anker SOLIX C300 accepts up to 100W of solar input. In real conditions that harvests about 375Wh on a sunny day (5 peak-sun hours).
Solar can keep up. String lights use about 100Wh a day at 5 hours of use, so with enough panels and good sun the Anker SOLIX C300 can run it indefinitely.
Tips
- LED string lights for a campsite or patio use 5–25W per strand.
- You’ll still have about 280W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The Anker SOLIX C300 uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
