A USB-C charging cable is not included with the Solar Cell Remote. You can charge the remote using the USB-C port on the bottom or by placing the solar panel face-up in natural or indoor light. For wired charging, we recommend using a Samsung-brand USB-C cable, available here: https://www.bestbuy.com/site/combo/cell-phone-usb-chargers/55d91e2d-59a6-4057-a896-fcbed32afab7
