Librem5 battery in a generic no name charger. Package on the charger placed aside showing the technical specification: Output 4.35V/600mA (and less important an usb output with 5.2V 1000mA). The PinePower at the upper edge of the picture doesn't have any function in the charging. The 0.1A power drawn from its usb-c port go to a pinephone idling.
