The Defender UV Sanitizer Box & Charger helps to clean your phone or other small objects. The 6 3/4" x 3 1/4" x 9/16" interior size is large enough to fit most phones and the dual function allows you to wireless charge and clean your mobile phone at the same time. To enable charging or sterilizing, connect it to a 5V wall plug, computer or other USB power device using the included USB Type-C to USB Type-A charging cable. Charge wirelessly or use your device's cable to charge using the USB-A output port, and use the kickstand to prop the device upright. The translucent cover blocks harmful rays while the lamps are on and they automatically turn off when the lid is lifted. Two settings allow for 15 or 30 minute sanitizing times.
