Introduction

Belkin has launched a new auto-tracking charging stand featuring Apple’s DockKit facial tracking technology. With a motorized base and an integrated wireless charging pad, the stand enables 360° horizontal and 90° vertical dynamic facial tracking — making it ideal for live streaming, vlogging, outdoor selfies, and other content creation scenarios.

The device includes a built-in rechargeable battery that provides up to 5 hours of additional runtime, ensuring flexibility for on-the-go use. The magnetic charging pad incorporates Apple’s MFM-certified MagSafe module, delivering authentic 15W wireless charging for iPhones when connected to a power source — perfectly suited for everyday charging needs. In this teardown, we’ll take a closer look inside to explore the internal components and engineering behind this innovative product.

Product Appearance

The front of the packaging features the Belkin logo, the product name, usage scenario imagery, key selling points, and the MFM certification mark.

The back of the packaging displays usage scenarios and a description of the product’s features.

Inside the packaging, in addition to the charging stand, there is a charging cable, a user manual, and a warranty card.

The included charging cable is a USB-C to USB-C type.

The charging stand is composed of three parts: the base, the support rod, and the MagSafe wireless charging pad. The base rotates 360° horizontally and, combined with Apple’s DockKit facial tracking technology, is designed to meet the needs of live streaming, outdoor selfies, vlogging, and other content creation scenarios.

The casing is made from renewable plastic materials, reflecting Belkin’s commitment to low-carbon and environmentally friendly practices.

The front of the base features a button to start and stop the auto-tracking function.

Above the button is an LED indicator light. A flashing white light indicates NFC pairing in progress, while a steady white light means pairing is successful. A flashing green light signals that facial tracking is active, and a steady green light indicates tracking is ready.

The top of the base is marked with an NFC logo. Simply bringing your phone close enables seamless connection without the need to download any additional apps.

The bottom is equipped with a non-slip pad and printed with the specifications.

Model: MMA008

Input: 15V 2A

The product has passed KC, CE, UKCA, and other certifications.

There is a standard 1/4-inch threaded nut at the center of the bottom, allowing it to be used with camera tripods and other mounts.

To the right of the threaded nut is a reset button; pressing and holding it for 6 seconds will perform a reset.

The back of the base and the support rod each have a power input port and an indicator light.

The power input port is a USB-C connector.

Indicator lights are designed on both the front and back of the base, allowing users to monitor the device status whether shooting from the front or rear.

The wireless charging pad and support rod are connected with an adjustable joint.

The wireless charging pad supports 90° adjustment.

The wireless charging pad features a built-in MagSafe magnetic module, providing a strong 10N magnetic attraction. It delivers 15W wireless charging for iPhones.

There is a touch-sensitive button located beneath the charging pad.

When supplying power to the charging stand, the measured charger output power is about 9.93W.

Well, those are all components of the Belkin 15W Auto‑Tracking Stand Pro with DockKit.

Summary of ChargerLAB

Here is the component list of the Belkin 15W Auto‑Tracking Stand Pro with DockKit for your convenience.

It continues Belkin’s signature minimalist design, made from renewable plastic materials that reflect a low-carbon, eco-friendly philosophy. The base and wireless charging pad support dynamic facial tracking with 360° horizontal and 90° vertical rotation. Simply bring your phone close to connect, with support for Apple Watch camera control. Powered by Apple’s DockKit facial tracking technology, it enables impressive results even when shooting solo.

It functions both as an auto-tracking gimbal and a wireless charging stand. The bottom features a standard 1/4-inch threaded nut, allowing it to be mounted on camera tripods and other supports. Notably, to provide 15W wireless charging for your phone, the device must be connected to a power source; the built-in battery is solely for powering the auto-tracking function.

After taking it apart, we found that the internal PCB connects to the motor, slip ring, battery, and other components via plug-and-play connectors. It uses the CPS CPS8852 protocol chip for input control, the MPS MP3432 boost converter for charging, the Nordic nRF5340 for Bluetooth connectivity, and Trinamic TMC2226-SA motor driver chips to drive the motors.
