The Tesla Wireless Charger is a 6000mAh (22.2Wh) battery-powered inductive charging pad that features the same design language used in other Tesla products, like the Powerwall. In addition to wirelessly charging your device, you can also power up your phone with the integrated USB-C cable. For non-USB-C devices, use the USB-A port to plug in any USB-A charging cable. The built-in USB-A cable can be used to charge your Wireless Charger from any USB port.
