The present invention relates to the technical field of a mobile power supply, and more particularly, to a portable mobile power supply.

The mobile power supply is a portable charger that integrates power supply and charging functions, and can charge digital devices such as mobile phones and tablet PCs anytime, anywhere. Mobile power supplies are output through a USB port or a self-contained cable and are widely used. Currently, when charging a mobile device with a mobile power supply, a wireless rechargeable mobile power supply has been developed in the prior art because it is relatively cumbersome to use because it is required to perform charging by connecting to a digital device through an output cable. Wireless charging mobile power supply does not require a USB line or power cable connection socket, so it can be carried outdoors and charged wirelessly. Its principle is as follows. That is, a wireless charging function is added based on a conventional mobile power supply device, and functionally, it is the same as a fusion of one mobile power supply device and one wireless charger. In other words, one wireless charging circuit has been expanded based on a conventional mobile power supply, and the wireless charging circuit includes a transmitting end (installed in a wireless charging transmitting device) and a receiving end (installed in a wireless charging receiving device), and transmitting and receiving ends. In a situation in which each coil is provided, a wired power supply is connected to the transmitting end coil to generate an electromagnetic signal, and the receiving end coil senses the electromagnetic signal of the transmitting end to generate a current for charging the battery.

In the conventional commercially available wireless charging mobile power supply device, since the wireless charging device such as a mobile phone having a wireless charging function is not fixed therebetween, a device such as a mobile phone having a wireless charging function can be easily removed from the wireless charging base. In general, artificial fixation is required because the charging device and the wireless charging device are easily separated from each other, so that charging may not be possible or charging efficiency may be lowered due to a shift in charging position. In the prior art, there is also a suction type portable mobile power supply, but the suction plate protrudes entirely from the charging device housing and the wireless charging transmission coil is still installed in the housing so that the suction plate not only occupies a certain space, but also the thickness of the housing is added to the charging distance. As the distance increases, the efficiency of wireless charging decreases, and it may even lead to situations where wireless charging cannot be implemented. Charging efficiency is particularly low when a protective housing is installed in the mobile terminal being charged.
