The current charging market environment is more complex, the major equipment manufacturers are not compatible with the current charging agreement, which gives the accessories manufacturers to provide a favorable revenue-generating But also to the user to add a lot of difficulty to buy. However, from the release of new products this year, manufacturers seem to gradually realize the charging protocol system a importance. Support the USB PD protocol power equipment, the more the original, including a hard to find millet 6, the recent speculation is very fire Nintendo Switch and the latest Version of the iPad pro. Although the official did not support USB PD charging as a selling point of publicity, but can clearly see him We want to start in the USB PD charge on the layout of the intention The

　Support for USB PD protocol more and more power equipment, but the official but not to the standard PD charger, which makes a lot of accessories manufacturers to find business opportunities. has been introduced under the USB PD charger accessories manufacturers a few, the type of charger is so much.

First, look

Focus on the charger manufacturer of accessories manufacturers - Kun Xing Technology recently has a new USB PD charger, in addition to support USB PD charging protocol, it also has one of the biggest features is the small size, it can be said that it is currently 24W level in the smallest PD charger.

Design fashion novel, the overall gray + white color, in line with the current mainstream aesthetic standards. PC material shell, the surface of the paint process and chamfering.

Mold AC pin design compatible with China's 3C, the United States UL and Japan's PSE, from the evaluation of the sample laser label is part of the Japanese PSE version, should be oriented to the mainstream of electricity sales.

Configure a USB Type-C output interface, and supports 5V / 3A, 9V2.67A and 12V / 2A three output modes. It is estimated to go OEM model, in addition to the necessary labels, and did not play the brand logo, there is no clear mark support USB PD protocol.

Comparison of ORICO 24W and millet 65W two USB PD charger.

Second, the test

To the purple rice 10 USB PD mobile power charging, POWER-Z display voltage 12.02V, current 2A, to 24.12W full load output, while supporting USB PD protocol power supply.

Charge Meizu pro6 plus, mobile phone power 23%. Support USB PD charging, 12.1V / 1.78A, power about 21.4W.

Huawei mate 9, the remaining power of 45%, 9.02V / 1.53A output, power of about 13.81W, from the POWER-Z parameters, and Huawei mate 9 handshake USB PD protocol.

to sum up
Kunxing technology produced this USB PD charger to maintain adequate capacity in the premise of taking into account the appearance. Do the same power with the smallest size really need to spend a lot of thought, I believe it's internal buck program and circuit layout must be extraordinary. Measured found that there is no label support USB PD protocol and can not change it is the fact that the PD charger, and enough practical output capacity has become a plus point.
