The UV-C case delivers a 99.9% sterilization rate and is the ideal portable solution for smartphones and other small objects like jewelry, earphones, glasses, masks, makeup tools etc. Simply connect the case to the accompanying 5000 mAh power bank, to a computer, or wall charger, place the object you would like to sanitize inside the bag and close the zipper. The UV-C lights will turn on automatically and an audio signal will let you know when the 5-minute sterilization starts and ends. To prevent accidental exposure, the smart zipper turns the UV-C lights off automatically when opened. Its portable design includes a hand strap and a front pocket where the inbuilt USB cable is stored and the power bank can be placed on the go.
