Teardown of Apple Vision Pro Battery
Introduction
On June 6, 2023, Apple released an unimaginable product at WWDC 2023 that is expected to change the future completely: Apple Vision Pro. As a revolutionary product that opens the era of spatial computing, it has a futuristic and technological appearance and integrates a variety of cutting-edge technologies. Featuring groundbreaking design elements such as a high-resolution display with 23 million pixels spread across two screens and a custom Apple chip with a unique dual-chip design, the Vision Pro promises users an unparalleled immersive experience.
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.

Here is the component list of the Apple Vision Pro Battery for your convenience.
The Apple Vision Pro Battery is made out of smooth, machined aluminum and comes with a woven power cable. It also has a USB-C port and an indicator light. Its model is A2781. It can support the output of 13V 6A. Its energy is 35.9Wh. It supports 5-20.3V input voltage and 3.3A maximum input current.
After taking it apart, we found the battery pack uses three cells. The battery pack is connected to the PCBA module via cables. The PCBA module is equipped with two synchronous buck-boost circuits, which are used for battery charging and buck-boost output respectively. The controller comes from RENESAS. Both synchronous buck-boost circuits adopt MOSFETs from VISHAY and are equipped with temperature detection chips for temperature monitoring and tantalum capacitors from KEMET for filtering. The battery pack has a built-in MCU from ST for overall control and memory from GigaDevice for configuration storage. Its PD controller comes from TI and uses a protection chip from TI to protect the USB-C port from electrostatic discharge.
The internal components are all from international first-line brands. The internal arrangement is compact, saving space and effectively reducing the size. Its workmanship is fine and reliable.
