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’t fully keep up. A desktop computer with monitor uses about 1.2 kWh a day at 8 hours of use, more than the Anker SOLIX C300’s best-case solar harvest. Solar will stretch the runtime but not sustain it.
Tips
- An office desktop plus a 27-inch monitor averages about 150W during normal work.
- You’ll still have about 150W 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.
