Apple announced the new MagSafe charger at the presentation of the iPhone 12. Despite popular belief, does not work with Apple 20W charger only, we tell you which chargers you can use.
Apple's new MagSafe system allows the wireless charging of the iPhone 12 to go up to 15W, in addition to opening the door to a large number of new accessories that take advantage of the iPhone's magnet system and its compatible cases. It seemed that only Apple's 20W USB-C Power Delivery charger was compatible with this new MagSafe, but the reality is that Apple hasn't whimsically limited this functionality, and you only need a charger that is compatible with very specific specifications that are also not arbitrary and that in AppleInsider have explained very clearly.
Power Delivery 3.0
Power Delivery is a protocol that ensures correct communication between the charger and the device that is recharging, so that the charging power of the device is controlled according to its need and specifications. In this way, even if you use a very powerful charger with a device that does not support so much power, you will not have any problem because It will only receive the power it can receive, to avoid damaging the battery or the device itself. With Power Delivery a charger can offer powers from 5V to 20V, and your device will receive only those that are compatible with it.
In mid-2019 an update of this Power Delivery was launched, version 3.0, which is the one with the new USB-C charger that is included in the iPad Air 2020 or that you can buy right now in the Apple Store for € 25. With Power Delivery 3.0 there is not only a charger-device communication to know what power it can accept, but also the adapter receives information about the temperature of the device or any possible malfunction.
The Apple charger is compatible with Power Delivery 3.0 with a power of 20W, but it also has very specific specifications that are what any charger needs to be compatible with MagSafe: 9V and 2.2A. Only with these specific specifications will you get MagSafe to recharge your iPhone 12 at 15W, and even if you use a more powerful charger (60W) the recharge of the iPhone with MagSafe will drop to 10W. And that's why the 18W charger that until now was included in the iPad Pro, which is not compatible with Power Delivery 3.0, does not work.
Afú, I finally understand it and it is clear to me, that yes, I did not complicate my life and tomorrow I get the apple one, 25 euros is not expensive, and for those of us who do not understand anything about volts, watts and amps, better go to the sure thing. Thank you for your very clear explanation.
So many so-called “specialists” on YouTube channels and podcasts complaining for the sake of complaining, without hardly studying the reasons and comparing the news against reliable sources… And it comes. Actualidad iPhone and, as always, giving us GOLDEN information.
