This is a very convenient way to charge up extra Joy-Cons and what I need since I rotate multiple Joy-Cons all the time. When the joysticks in the grip run out, I can easily swap them in for a charged pair thanks to this handy docking station. The DOBE dock connects to the USB port on the switch dock. Batteries and cables are not required. The Joy-Con dock even has a USB port. That means no port is sacrificed to use this dock๐. The assembly was very easy and quick; There are two pieces that fit together around the Switch dock. There is no interference when placing or removing the switch, or charging the switch. Another thing that impressed me about this dock is that it doesn't feel cheap. The parts are made of thick plastic. It feels solid and heavy, and the two pieces slide smoothly and seamlessly into each other. The DOBE Joy-Con Charging Dock is a convenient and affordable option for keeping your Joy-Cons charged and ready to go. If that's what you need, I highly recommend it๐
