A compact mobile electronic device servicing kiosk which provides speed charging and UV sterilization services to at least one mobile electronic device locked in at least one compartment. To achieve key-less access to the compartments, an interactive computing interface keeps temporary records of authentication characteristics collected from authentication means such as a biometric device or a payment device for compartment access authorization. The interactive computing interface also serves as multimedia content display and user interaction device. The interactive computing interface is wireless accessible to local area network or to the Internet which enables download and upload content from and to various external sources as well as enabling remote control for operation and maintenance purposes. Given the security and mobility features, the kiosk fits perfectly in any public locations where users can conveniently obtain a quick service without having to wait in front of the kiosk during the service session.
