I have 2 more Joy controllers so we can all play games together but I didn't want to mess around with a charging dock or swap out controllers on the switch itself to keep them charged. This product solved that problem. Includes 2. TWO USB Type-C charging cables - also a thick cable. I am currently using one of these at work. Joy-Cons are inserted directly into the brackets (+ or -). Fits perfectly. The holders are very light and balanced. I couldn't tell where the backup battery was stored. I wonder if he's there. ;-) I'm just worried about the bubble shape on the back. Seems VERY weak. However. As long as the Joy-Con is connected to the mount. Should be good. How much did it cost. This is theft. Therefore still 5 stars.Plus. 2 additional Type-C charging cables.
