[0002] Multi-channel fast chargers are popular because they can efficiently charge multiple devices simultaneously, especially fast chargers that support the USB PD protocol, which can provide better charging power for different devices and improve the user experience.

[0003] However, traditional chargers have certain limitations in terms of charging speed and compatibility. They charge slowly and cannot meet users' needs for fast charging. Moreover, different brands and models of devices often use different charging interfaces and charging protocols, resulting in fewer supported battery models. This leads to prominent compatibility issues between chargers and batteries, requiring users to equip different devices with different chargers. In addition, existing chargers have fewer charging channels, mostly single-channel or dual-channel, and their structure is also limited, with most only equipped with separate PD, DC input / output or V-port expansion, making them inconvenient in actual use. Utility Model Content

[0040] The remaining structure is the same as that in Example 1.

[0041] Based on embodiments 1-2, the working principle of this utility model is as follows: The process of installing the battery inside the battery cavity 4 is as follows: the charging contact of the battery faces the charging contact 6, and then the battery is pushed flat into the battery cavity 4. When the battery is pushed flat into the battery cavity 4, the battery abuts against the protruding end of the pressure strip 11, and the pressure strip 11 is pressed down towards the inside of the machine compartment 2. At the same time, the two sides of the battery are stuck between the two pressure cavities 9. Under the elastic action of the pressure strip 11, the pressure strip 11 abuts against the bottom of the battery, and the battery is pressed into the inside of the battery cavity 4 for fixation.

[0042] When the battery needs to be removed, simply pull it outwards, and the retaining strip 11 will reset under its elastic action.
