Nintendo:

Launching on July 13 at a suggested retail price of $19.99, a new adjustable charging stand for the Nintendo Switch system makes playing in Tabletop mode easier than ever. With a handy port for an AC adapter on the side, the adjustable charging stand allows the Nintendo Switch system to be charging while in Tabletop mode, enabling longer play sessions.
Looks like a must have for traveling. Also, since it's official, less likely to brick your system!

For just $20, I’m definitely considering it.
