TYPEC power cord
01Charging extension cord
I. Introduction
A few days ago, I connected and extended the power cord in the Apple data cable through a wire. As a result, I couldn't use it to charge the Apple phone. There is now a Type-B USB to Apple charging port circuit. Use this Type-B USB socket to make a 5V extension cable. Only connect the power cord from the outlet to a low-voltage power source. There is a TypeC 5V low-voltage DC power supply here, and I happen to have a TypeC connector on hand. They provide 5V power to the Type-B socket. ·Now everything is ready, all you need to do is make it.
2. Make a power extension cord
In the signal cable in the USB socket, the positive pole of the power supply is on the left and the negative pole is on the right. Connect the TypeC plug and socket together through a two-wire connection. Only power comes from the Type-B outlet. Later, connect the socket to the Apple data cable to test whether it can charge the phone.
What is very strange is that when testing this TypeC power supply, it is 2.8V after the voltage of the interface. This is indeed a question, why can only 2.8V be output through this connector. The low-voltage power supply can provide normal power supply to other TypeC devices. So it's really weird.
※ Summary ※
Today I originally planned to use this TypeC lead to make a charging extension cable, but for some unknown reason, this cable can only draw 2.8V power from the power socket.
