Description

A PCBA structure of fast charging mobile power supply

technical field

The utility model relates to the technical field of fast-charging mobile power PCBA application technology, in particular to a PCBA structure of a fast-charging mobile power supply.

Background technique

Mobile power, also called power bank, travel charger, etc. A portable charger integrating power supply and charging functions, which can charge mobile phones, tablet computers and other digital devices anytime and anywhere. Generally, lithium batteries (or dry batteries, less common) are used as power storage units, which are convenient and quick to use. The mobile power supply is usually designed to be light, compact, and easy to carry, so as to facilitate mobile use. After the charger fully charges the mobile power, it can charge your digital products four or five times. Connect your digital devices with a suitable connector or directly connect a USB On-the-Go (USB-OTG) portable device with a usb cable. For small devices, the mobile power supply starts to supply power or charge digital devices after automatic detection or simple switching.

Most of the fast-charging mobile power supplies currently on the market convert the internal lithium battery voltage 3.7V to 5V-9V-12V high voltage and high current at the same time, the heat generation increases sharply, and a certain amount of heat will be generated during use, which cannot be quickly Good heat dissipation will lead to insufficient heat dissipation performance of the product and shorten the service life of the product.
