USBThe socket is one of the most frequently used electrical interfaces in daily life. In many cases, it is only used for power supply. Only when data is transmitted will a USB HUB be used as an interface expansion. HUB is what we often call a hub. For example, when the USB interfaces of computers and notebooks are not enough, USB HUB will be selected for expansion. If you need to use multiple USB devices in daily life and only need power supply but the interfaces are not enough, you can make a simple USB power splitter by yourself, so that one interface can output multiple power supplies. Of course, the normal use of each device can only be guaranteed when the power supply USB power is sufficient.
So how do you make a USB power splitter yourself?

1. Preparation
1, Effect diagram
First, let’s take a look at the finished product of the USB power splitter we made this time, the effect of 1 to 4, which is mainly composed of 1 USB male socket and 4 USB female sockets. The USB male socket is used as the power input, and 4 USB female sockets are connected in parallel as the output to achieve the 1-to-4 function:
