Wireless power system for portable electrical devices on marine vessels and land vessels

A system for wirelessly powering an electrical device in a wet or outdoor environment from a wireless transmitter sealed to a mounting surface. The electrical device is in a portable housing removable from the surface, and includes a wireless receiver adjustably disposed in the housing to change the position of and to fix the receiver in a desired position within the housing. The receiver and housing are adapted to be positioned adjacent the transmitter. The position of the receiver within the housing may be adjusted to create a desired spacing distance between the receiver and the transmitter and the receiver locked within the housing to fix the position of the receiver within the housing at the desired spacing distance with the transmitter. This then permits wireless transfer of electrical energy via an electromagnetic field from the transmitter to the receiver to provide power to the electrical device.
