It is not the first time that a USB-C charger for iPhone and iPad since Apple introduced this connector in its products with the 2015 MacBook. Since then it has been taken for granted that Apple would inevitably change all its connectors to this new standard, there was even talk that the iPhone would abandon the Lightning for USB-C.
But everything has gone much slower than expected (and desirable) reaching the ridiculous situation that we need a third-party adapter to be able to charge an Apple product such as the iPhone or iPad into another Apple product, such as the MacBook or MacBook Pro. It seems that this will change shortly with this new charger that we can see today in these renders.
The information comes to us through Chargerlab who claim to have reliable information within Apple's production chain and have made these renders with that data. It is a European plug that is very similar to the current one, but with a much more rounded and shorter profile. Only a small hole for the USB-C breaks the surface of this charger, supposedly made of glossy white plastic, as Apple is accustomed to us.
The charger would have a power of 18W, enough for the fast charge of the iPhone, as we can see in this MacRumors table in which the charging times of the different methods compatible with the iPhone X, 8 and 8 Plus are measured. As you can see in the graph, faster charges are not achieved from 18W of power., getting to charge half the battery in half an hour, and 80% in sixty minutes. The iPad would also benefit from this new charger, as it now incorporates a 12W one.
