It’s not just the MacBook Pro that we can order from a while ago! Apple has also just put the 35W USB-C Dual Port Power Adapter on sale, priced at €65. It also appears on Amazon.
This accessory will of course allow you to charge two devices simultaneously, it will be a bit tight to power two 16-inch MacBook Pros in the middle of work, but for an iPhone and an iPad, or a MacBook Air and an Apple Watch, it will do the trick.
Deliveries of this product announced after the WWDC keynote are scheduled from June 21st. Note that this will be the adapter supplied with the new MacBook Air M2 (10-core GPU, 512 GB of storage).
