Description

The Adafruit USB / DC / Solar LiPo Charger is a feature filled single Lithium Ion / Lithium Polymer battery charger. The charger can accept power from a 6V solar panel by way of the DC barrel jack, 5V power by way of the USB-C port, and conventional 5VDC power through the DCIN pins on the circuit board and will charge / keep a battery topped up automatically when power is available.

The charge circuit has intelligent load sharing and automatically uses input power when available to prevent the constant charge / discharge of batteries. On loss of charge power / solar power the output power is immediately drawn from the battery to prevent any interruptions to the supply.

Updated September 2024 to a USB-C connector.

Please note: Light soldering is required to attach the included capacitor.
