Abstract

The present invention provides a wireless charging equipment for mobile phones for mobile phones. The charging equipment comprises a protection cover with a switch port and a charger with an internal battery arranging therein. The mobile phone is enveloped in the protection cover, one end of the switch port is electrically connected with the socket of the mobile phones while the other end is electrically connected with the charger which is detachable from the switch port, the mobile phone then could be charged via the electricity provided by the internal battery. The charging equipment is facilitated to carry, when travelling to some places where it is not easy to find somewhere to charge, people can charge the mobile phone by using the internal battery of the present invention so as to extent the working time of the mobile phone. When charging is not processing, the protection cover of the present invention can serve as a common mobile phone protection cover, avoiding the mobile phone from scratching or crashing. Moreover, contact points are positioned on the protection cover and the charger of the present invention, The contact points can be designed in a consistent pattern, enabling different mobile phones to charge by using the same charger and protection cover, thereby it can be universally used.
