Portable USB hub stand for Nintendo Switch, allows LAN adapter and wired controller connection while charging. - Model: Portable USB Hub Stand 2-Port - Compatible Models: Nintendo Switch - Functions: Can use LAN adapter while charging - Manufacturer: HORI - Model Number: NS2-039 Thank you for viewing. I used this as a temporary solution until I bought a monitor, but I'm selling it now that I have a monitor and no longer need it. I've used it for a while, so I don't recommend it to those who are concerned. There is a small amount of dirt on the charging port, but otherwise, there are no major stains.
