I only have the original Switch released in 2017, and I've only tested it on the original Switch. In theory, the battery life of the upgraded version should be the same as the original, and it can be used. Other versions are not supported for now.

The height of the base has been increased under the original printing configuration to prevent the switch from falling when it is placed.

The original model was placed with the Switch screen facing the interface, but now it is placed in the opposite direction. At the same time, a ventilation gap is left at the back when placing it.
