I've been using the HORI Joy-Con charger for about two weeks now and couldn't be more impressed. The connection is made directly on the back of the switch to one of the USB ports (see photo). Cons Joy is easy to put on and take off, it doesn't use the clip system that all Nintendo products use which drives everyone crazy at times trying to undo the wrist strap to reattach the joycon to the console or charger can be - graaaaa. *clears throat* The stand also indicates if the Joy-Con is charging, via a small LED that turns off when fully charged (see photo). There's also plenty of room around the Joy-Con to protect the armor with a gap of about 1cm at the bottom when fitted. I just love that my controllers are always charged and my next Mario Kart marathon is always there.
