Retro Receiver NES / SNES Classic

The Retro Receiver is a Bluetooth dongle; it enables 8Bitdo-, PS3-, PS4-, Wii Remote and Wii U Pro-Controllers to connect to your NES or SNES Classic, getting rid of the way too short cable controllers!

It fits beautifully into the original NES Classic controller ports, supports multiplayer games (two receivers and controllers needed)
No additional AC Adaptor needed: It gets the needed power directly from the controller port.

Additionally, it can also be used as a bluetooth dongle on a PC.
