A document published by the Federal Communications Commission (FCC) on Monday shows that the new MagSafe charger is expected to be released with the iPhone 13 series. According to the published certification documents, shared the charger’s occupied bandwidth, radiated emission and other regulatory measurement reports, and pointed out that a magnetic charger was successfully approved, which can provide 15W power for iPhone and 1W power for AirPods.
Although the brand term MagSafe is not mentioned in the document, it is an iterative version of the current MagSafe charger from the illustrations and specifications. The output power is the same as the current model, and the drawings included in the file show a sphere, the size of which is comparable to existing accessories.
It is unclear what updates Apple has made to the charger because the test data did not show significant operating changes. Apple may be implementing minor internal changes or component swaps to improve power transmission and efficiency, although there is no evidence in the FCC documents to indicate such improvements.
A rumor in July indicated that Apple plans to expand the iPhone’s charging coil in the iPhone 13 to better manage heat dissipation and perhaps increase system power. A larger coil area will require a redesign of MagSafe, which will require a new round of regulatory testing. The rumors about increased power output seem to be unfounded, at least on this particular device.
The updated MagSafe cable and charger are labeled A2548, which is much higher than the current A2140. In mid-August, the UL Verification Service Department conducted tests using Apple’s 20W and 30W power adapters. The final report was submitted on August 21.
