Apple may finally be warming up to fast charging. Technically, the iPhone 8 and X support fast charging, but actually finding a charger to pull it off is trickier than it should be not to mention costly.
Going forward, Apple may start providing 18 W chargers with a USB-C port and a USB-C to Lightning cable. Chargelab has created 3D renders of that charger based on info from Apples supply chain.
It deviates from Apples current square-ish designs, but looks pretty standard. Speaking of, Apple will reportedly use the USB Power Delivery standard, which is also used in MacBook chargers.
Besides faster charging, there are more advantages to this move. For one, youll get a cable that can connect your Apple phone to your Apple laptop.
