This is a pretty good charger, I really like it, but it has a pretty serious flaw; If you plug it into the Switch's base via USB, your Switch will think the correct Joy-Con is connected. As a result, you cannot connect your joysticks to the Switch and use it offline. It took me a while to figure it out, but now I've plugged it into the USB socket and magically my right Joy-Con is working again. Other than that it's a great charger, love the way it looks and you can use it to charge your joysticks too. Just don't connect it to your base.
