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).
Tips
- Most phones hold 12–19Wh. Charge from a USB port rather than the AC outlet to skip inverter losses.
- Running it from the Anker SOLIX C300’s DC port instead of the AC outlet avoids inverter losses: about 20Wh more usable energy.
- The Anker SOLIX C300 uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
