US Patent 9800291 Data backup and charging device for communication devices

A device interfaces with a mobile communication device, for example, a smartphone or tablet, that has data stored in a memory. A device body has a data storage element integrated inside the device body. A first interface receives alternating current (AC) voltage from a mains power supply. A second interface detachably and electronically couples the mobile communication device to the data storage element. The second interface also provides direct current (DC) voltage to the mobile communication device. A data management application on the mobile communication device issues a command for the device to receive a copy of a subset of the data stored in the memory of the mobile communication device. The received copied subset of data is stored in a protected format having at least one layer of protection in the data storage element. A unique identifier associates the stored subset of data with the mobile communication device.
