Disclosed is a wireless charging device with a support and relates to a magnetic-transmission wireless charging device which uses a magnetic transmission principle and uses an external magnet to drive an internal magnet in a mobile device to rotate so as to enable the internal magnet to drive a motor to generate power and then a mobile power generation device installed on the mobile device is charged. At the same time, the wireless charging device is provided with the support so that the mobile power generation device can be supported. Compared with the prior art, the wireless charging device is capable of wirelessly charging the mobile device at a longer distance and during charging, any operation can be performed and at the same time, restriction from a power line does not exist; and the wireless charging device is provided with the support so that the wireless charging device can be placed at different places. The wireless charging device solves problems that in the prior wireless charging technology, the charging distance is short and that operations on a mobile device is subjected to restriction from a power line in wired charging.
