**The MagPi Magazine** highlights a convenient solution for charging lithium-ion batteries with solar power: **Adafruit’s Universal USB / DC / Solar Lithium Ion/Polymer charger**.
This innovative charger simplifies the process of safely charging lithium-ion batteries using solar panels. It features a dedicated circuit that handles the complex aspects of charging, eliminating the risks and uncertainties often associated with solar charging.
The charger boasts a user-friendly design with a barrel jack connector for solar panels and a standard connector for batteries. At its core, the bq24074 IC intelligently manages the charging process, ensuring optimal current draw from the solar panel.
While a slightly newer and cheaper design for solar charging using the bq24074 IC is available, Adafruit continues to stock the older design for those who require it.
The MagPi gives the charger a perfect score of 10/10, calling it “a great solution for solar power management.”
This charger is a must-have for makers looking to power their projects using renewable energy. It’s a testament to Adafruit’s commitment to making electronics accessible and enjoyable for everyone.
