This mount will hold a Google Pixel 2 with a slim case. This means that this will not work with a bare Pixel 2 (without a slim case).
The mount hole is threaded with 3/8-16, so an adapter screw will be very easy to fit.
There is a "cut out" to be able to fit a usb charging cable.
1/4 => 3/8 screw adapter like the one in one of the attach pictures.
