Internal Construction
Removing the base cover reveals the internal assembly. The interior is secured by multiple screws around the perimeter, with the PCBA vertically mounted onto the internal bracket.
The interior of the removed base cover features two semi-circular, heavy metal counterweights. These are integrated to increase the overall weight and lower the center of gravity, preventing the charger from lifting when a mobile device is detached.
Two USB-C female connectors are soldered onto the PCBA. One serves as the external power input interface, while the other provides a 5V power output to the smartwatch charging module.
The connection between the mainboard and the upper charging module is established via multiple wires, with all solder joints reinforced by potting compound.
