With the development of science and technology, more and more devices need to be charged. It is common for two or three charging heads to be placed in the schoolbag. Now there is an urgent need for a charging head that can be charged by two ports. Beisi appeared. Beisi 30W charging head, with dual port output, supports multiple protocols, and can also charge laptops that support PD fast charging.
appearance
The packaging box of Beisi 30W PD dual port charger uses white as the background color, yellow as the bright color, with the Baseus logo on the upper left and PPS/QC3.0 fast charging on the upper right. The products are printed in the center, and the materials are different. Type-C+USB, 30W Power HW 5A Super quick charge， It means that the charging head supports Type-C and Type-A charging, the maximum power is 30W, and Huawei 5A fast charging, that is, SCP fast charging.
More detailed information is printed on the side of the package in both Chinese and English.
The charging head is protected by a ring of plastic film. The foldable design of pins is convenient for storage and can effectively prevent scratches on other electronic devices, giving this design a favorable comment.

The biggest highlight is that it supports Huawei's FCP and SCP protocols.
Type-C
Another charging interface, Type-C, supports the same protocol as Type-A, with PD3.0 fast charging support and PPS charging protocol.
PDO message
Use the PD trigger function of the black gold meter to obtain the following PDO messages
The supported PD gears are: 5V/3A, 9V/3A, 12V/2.5A, 15V/2A, 20V/1.5A, 3-5.9V/3A, 3-11V/3A, including 5 fixed voltage gears and 2 PPS intelligent voltage gears.
