Wireless Power Transfer (WPT) has been used to transfer small amounts of power over small distances to run smartphones, RFID tags, smart watches and even biomedical implants without any electrical contact. With the increase in the number of portable personal consumer devices, the number of power access points needed in public places will be more. In this paper, a wireless power transfer system is described that includes features that allow many users to connect to a single supplier in public spaces such as airports or in commercial establishments such as restaurants or hotels to allow a user to recharge one or more portable electronic devices. The system including a mobile app allows users to detect power hot spots and be automatically billed for the power consumed. The system will decrease power theft and squatters in public places who use power illegaly or indiscriminately.
