Review on Switch Joy Cons Controllers Charging Dock with Extended USB Port - Portable Desktop Stand for Convenient Charging - Black/Red by Nick Bigalow

It does the job (nice colors and looks) but doesn't sit very securely on the Switch. The design could have been better. It's held to a Switch dock with a USB connector and a very thin sticker that sticks to the opposite end of the dock. After connecting, I noticed the lights flashing randomly every few days or so. I think it was constantly grilling my USB port so I just unplugged it from the dock and now use it as needed.
