Peripheral device company ChargerLab has disassembled and analyzed Apple's first GaN charger, the 140W power adapter for the 16-inch MacBook Pro.<\/strong><\/p>\n\n\n\n

Even before the official launch, it was revealed that Apple is using gallium nitride technology in its new 140W power adapter. Now ChargerLab has taken a closer look at the charger. The company focuses on the fact that this is the first time Apple has used GaN and says it expects "more and more manufacturers" to use the technology as Apple is an industry leader. The charger is Apple's first to use gallium nitride, or GaN for short. By the way, did you know? GaN is a material that allows for higher voltage capacity and less energy loss, e.g. through heat. The efficiency of the material allows manufacturers to produce physically smaller chargers with similar capabilities to traditional production methods.<\/p>\n\n\n\n

Apple's 140W power adapter can also be purchased separately<\/h3>\n\n\n\n

Apple's new charger also implements the USB-C Power Delivery 3.1 standard, making it compatible with other hardware that uses the same standard. The 16-inch model can be charged with either MagSafe 3 or Thunderbolt 4. However, the 140W fast charging capability is only achieved when the MagSafe connector and the Apple charger are used together. As for the actual teardown, the video<\/a> general measurements and tests of the power supply. But ChargerLab disassembles the entire case to get a better look at the innards. If you want to see Apple's specific chip setup, you can do so from minute 7.35<\/a> do. It's definitely worth seeing. Apple's new 140-watt power adapter is included with the new 16-inch MacBook Pro. But it can also be purchased separately for 105 euros. (Image: Apple)<\/p>\n\n\n\n
