When Apple unveiled the new MacBook Pro, the company also introduced a new 140W USB-C charger that comes in the box for the 16-inch models. Although similar to any other regular charger, Apple’s 140W charger is the first that the company has made with gallium nitride (GaN). Now a deardown shows all the details of the new 16-inch MacBook Pro charger.
YouTube channel ChargerLAB has shared a video showing the entire disassembly process of Apple’s 140W USB-C charger. What makes this charger interesting is its new technologies as it uses the USB-C PD 3.1 standard that can deliver up to 240W of power. In addition, this is also Apple’s first power adapter with GaN.
Gallium nitride, or GaN, is a material used for semiconductors that produces less heat. As a result, the components can be brought closer together and the charger can be more compact without affecting its safety. To get the maximum 140W of power while charging your MacBook, the new USB-C to MagSafe 3 cable is required, as there are no standard USB-C cables yet compatible with the new standard on the market.
As we move on to disassembly, ChargerLAB shows that there is no easy way to disassemble Apple’s charger. They had to cut through the hard plastic shell to access the internal components of the power adapter, which of course will cause permanent damage to it.
Once the charger is disassembled, we can see a quite robust structure inside. The plastic shell is really thick and there is a black glue to hold the main module in place. As noted in the video, there are also several thermal adhesives and graphite thermal pads on top of the chips for heat dissipation and protection.
For those interested in knowing all the details about Apple’s charger components, ChargerLAB’s video shows an in – depth look at what each component does – including the new GaN chips. You can watch the full video below:
