The USB interface above the switch base currently has the following functions:
1. Plug in a USB charging cable to charge other devices.
These devices can be the Pro controller of the Switch, or it can be an Android phone, an iPhone, or even any device that can be charged with USB.
2. Plug in the cable network adapter.
The network module of the Switch can only support 2.4G network. There is no support for 5G networks, so many times the Switch's network, especially when fighting, may not be so stable.
At this time, buy a USB network card, connect to the USB interface, you can use a wired network card to play, and the degree of network stability has also increased significantly.
3. Connect the Bluetooth transmitter
swtich doesn't support Bluetooth headsets, which annoys many people who prefer Bluetooth headsets. If it is a landline mode, as long as you buy a Bluetooth transmitter and plug it into the USB port on the base, then the Switch directly supports Bluetooth headsets
4. Connect some other usb power supply devices.
For example, small fans, small night lights, and even digital black technology toys are good choices.
The above is so far I know the role of the usb interface on the switch base line, I hope to help you.
I am a switch game anchor, but also a game lover, other questions about switch or console can also ask me Oh ~
