Introduction
---------------------------------------------------------------
In order to reduce the discomfort of users when wearing it, the Vision Pro and the battery are designed to be separated. The battery is similar to a portable power bank. You can charge the battery via the USB-C port, and there's a dedicated cable for connecting to the Apple Vision Pro.
ChargerLAB recently conducted a test on the compatibility of the Apple Vision Pro Battery. This time, we are going to take it apart to see its internal components and structure.
