The UVClean P4000 5x Flip is a power bank for a new age. Featuring a 4000 mAh battery that can provide a full charge for most smartphones, dual Lightning and Android connectors (one on each side), a Type-C adaptor tucked inside, and a standard USB port for almost any cable you've got. But, the real beauty of this device is the built-in Ultraviolet Light. It uses short-wavelength ultraviolet (UV-C) light to kill or inactivate microorganisms, so you can sterilize on-the-go.
