- switch charges (very slow) - AC adapter required - buy device + cable separately = $50 - works great - small/compact First, it charges your switch; only very slowly, probably to make sure it doesn't fry and permanently disable your Switch's black screen. However, when the console is used, the battery drains more than it recovers, which I think is normal (given the alternative). It really works amazing. Only HDMI does not work. For those who say it's buggy, it needs a power supply (USBC). It's a great little thing that's great for smaller TVs and as a second docking station. It's a bit annoying that the cables are connected from the side. Depending on your setup, this might be worth considering. One thing should not be forgotten. Given that it comes cordless (as the description states), it costs about $50 to install and run. If you don't already have extra HDMI and USBC cables. Overall I think it's a bit pricey for what it is.
