So when you use the booster cable, you can boost the output from 5V to 7.5V and 9V with the switch.

The USB terminal uses an L-shaped connector that is resistant to problems such as disconnections.
It also reduces the rattle of cable at the chest.
Please check the size before inserting a different size of the plug.
