This is a stand for ISDT POWER 200/200H/200X series charger, which has a MagSafe compatible charger on top of the unit, other than 3 USB-C and 1 USB-A charger ports.
This stand makes the charger slanted, so that it can enable iPhone StandBy mode (displaying clock, widgets or photos on horizontal, always-on with iPhone 14/15 Pro series).
You can put the either side of the charger (charger display on top/bottom) on the stand, however, it might not fit a Max/Plus models with a thick case depending on the orientation.
The author marked this model as their own original creation.
