Try using USB Type-C wall sockets! You can also customize interesting sockets.

　Recently there is an embedded USB connector, such as the wall sockets common in The Business Inn and cafes. And in coffee shops and other places, you can see not only 100V sockets, but also USB sockets.

　So far, when it comes to USB charging, the so-called USB guy's "Type-A connector" is only about 2.1A (10.5W), but recently there have been ultra-high-speed charging USB sockets that can switch to the USB PD equivalent of 5max 9max 12V.

　Smartphones also switch from Micro USB to Type-C connectors, almost all of which support ultra-fast charging. Although there have been smartphones corresponding to ultra-fast charging since a few years ago, that specification fights with the Qualcomm and USB specifications that make smartphone SoC, so popularity has been delayed, but recently the specifications have finally been unified, and it can be said that there are signs of popularity.

　With such a background of the times, the USB socket finally appeared the Type-C connector. In addition to the only Type-A 2.1A standard, there are 15W types of Type-C+A connectors from electrical companies and 18W types of Panasonic.

　This time, I use Panasonic's variable voltage USB wall socket with Type-C connector "WN1477" to make my own information socket. In addition, when embedded in a wall socket, the qualification of an electrical engineer is required, please note.
