Description

technical field [0001] The invention belongs to the field of wireless charging, and in particular relates to a charging treasure with wireless transmitting and receiving functions conforming to the QI standard. Background technique [0002] In recent years, portable electronic devices, such as mobile phones, tablet computers, etc., have been popularized and used on a large scale. Such electronic products generally consume a lot of power, so mobile power banks have emerged as the times require and have been widely used. Mobile power, also known as power bank, is a portable charger that integrates power supply and charging functions. It can charge mobile phones and other digital devices anytime, anywhere or standby power. Generally, lithium batteries or dry batteries are used as power storage units, usually with large capacity. , multi-purpose, small size, long life and safety and reliability. The traditional mobile power supply is connected to the USB port of the portable el...

AI Technical Summary

Problems solved by technology

[0005] Therefore, in view of the above-mentioned problems, the present invention proposes a charging treasure with wireless transmitting and receiving functions. When charging its own battery, it still needs to be connected through a wired connection, and it still does not get rid of the problem of carrying a data cable; in addition, it also solves the safety problems that the existing power bank does not have a waterproof function, is easy to enter water, and is prone to leakage.
