A mount for the Nintendo Classics Virtual Boy that lets you charge (or use a wired gamepad) and play simultaneously. In order to use this, an angled cable or angle adapter is required. The one I am using (and the one this model was optimized for) is the "UGREEN 40Gbps Right Angle USB C Adapter", and can be bought here (US Amazon). The mount allows for angling the cable out both the left & right sides of the console.

Comes with two cable holds on either side that will friction-fit most thick plastic-coated cables - such as Nintendo's own USB C cables for charging and USB power.

I have not tested this for Nintendo Switch 2, so use at your own risk.
