I really liked the original model but it didn't fit my google home nest mini so I made the hole in the middle a little bigger so the cable goes through. The original model uses micro USB and my model uses a circular DC adapter. I'm not sure exactly what the cable is called, but you can see the pictures in case you have the same one as me.
