Recently learned that Apple's original USB PD charger has been successfully cracked by Chinese engineers. The third-party USB PD charger can also complete the complex communication process with the computer, and also supports Apple's serial number query.
As we all know, Apple's equipment requirements for charging accessories have always been more stringent, the most common of which is the MFi data cable, but Apple's requirements for charging accessories are not limited to charging cables, and also have strict requirements for chargers.
For USB PD chargers for Apple laptops, each charger has a unique serial number that can be queried by the laptop during charging.
The serial number has become the most essential difference between Apple's original USB PD charger and third-party USB PD charger. So far, many Apple's original chargers manufactured by third-party accessory manufacturers on the market can basically do only To the shape, but does not support Apple laptop recognition, not to mention the 'serial number'.
This is not known to the majority of users, and is also the most taboo of these 'original charger' manufacturers.
Measured using Apple's original 29W charger to charge New MacBook, you can find the serial number 'C4H618502NTG2VCB8', in addition there are some other defined information.
Use the cracked version of the 30W USB PD charger to charge the New MacBook. The serial number is 'C4H5286025PG2VCAZ' and the output power is also changed to 29W.
With the conventional USB PD charger, only one parameter of maximum charger power can be obtained when reading information, and other parameters cannot be obtained.
The original apple charger's cracking difficulty is no less than the USB-C to Lightning fast charging line's crack, even more difficult, because it has very strict requirements for the overall architecture of the protocol chip in the USB PD charger.
About Apple's original charger was cracked, the engineer consulted through the network to learn that The cracking solution is to burn a reverse code in the charger's protocol chip, and this code is captured by ChargerLAB POWER-Z to capture the apple's original charger and computer's communication process. Simply put, it is copied. An identical Apple charger.
Also learned from the supply chain, Apple's upcoming 18W USB PD charger will also be written into a specific serial number and specific data packets, and the charger and the mobile phone will also carry out complex communication, and this communication process It is also possible to be encrypted by Apple at any time to improve Apple's MFi certification system.
At that time, the conventional USB PD charger will not be able to quickly charge the Apple mobile phone. The third-party USB PD accessory manufacturers face enormous challenges.
For the Apple charger to be cracked by Chinese engineers, what do you think?
