With the introduction of the M2 MacBook Air, Apple unveiled a new charging accessory that had previously been rumoured. The new Dual USB-C power adaptor. The accessory enables dual charging at up to 35W. It was unclear how wattage power would be divided when multiple devices are connected. Now we have an answer thanks to a new support document from Apple.

In the support document, Apple outlines the following:

To charge two devices, connect your devices to either port on your power adapter. When you connect two devices, power is automatically distributed between them based on their power requirements. For most devices, power is shared evenly when you have two devices charging at the same time. For example:

  • If you connect a Mac notebook and an iPhone or iPad, each device receives up to 17.5W.
  • If you connect an iPhone and an iPad, each device receives up to 17.5W.
  • If you connect a Mac notebook or iPhone and an Apple Watch or AirPods, the Mac notebook or iPhone receives up to 27.5W and the Apple Watch or AirPods receive up to 7.5W.

Notably, Apple states that an iPhone can receive up to 27.5W of power while dual charging an Apple Watch or AirPods. Currently only the iPhone 13 Pro Max supports this charging speed but it’s pretty likely that the iPhone 14 series will too. You can bet that Apple will want to upsell consumers on this new dual-power adaptor.
