This product work excellent to cool down the overheating issue that my phone used to suffer aftet using VR after 20 minutes but with CUVR Ultimate it works for hours non-stop and also it charges my phone wirelessly

The product will allow you to use the vr until your eyes hurt.

Meaning you can't be using product to both charge your phone, play VR, cool your phone at the same time if you don't want to rely on the internal battery of the accessory.
