A:Answerbigmac - The Solar Cell Remote charges through light using the solar panel on the back, or via a USB-C cable connected to the port on the bottom of the remote. A USB-C cable is not included, and we recommend using a Samsung-branded USB-C cable when charging by wire for optimal compatibility.
