I have a Meta Quest 2. This charging dock is a great addition to the VR. Not only it can charge the Quest itself, it also can charge the two controllers. The rechargeable battery for the controllers are included. You will need to remove the case, put in the rechargeable battery and use the new case come with the charging dock. The metal part of the battery has to be face to the outside so it can connect to the charging station through the case. It feels good to not have to replace the battery every now and often.
The magnetic charging connection for the Quest works well so I don't have to insert the USB-C cable into the unit multiple times everyday. I also like the LED indicator on the charging dock so I know the charging is complete from the front. Overall it is a great purchase and highly recommended for every Quest user.
