Will MacBooks become wireless chargers
#1
https://www.cultofmac.com/700575/apple-m...ch-patent/

Apple hasn’t abandoned the idea of building reverse wireless chargers into its devices. It’s been considering for years the idea of enabling a MacBook to send power to an iPhone without the hassle of wires. And the ability to recharge another handset, or an Apple Watch, was supposed to be a feature of the iPhone 11, but it didn’t happen.
Nevertheless, undeniable evidence that Apple engineers are still working on the technology came to light on Thursday.

Apple still pursuing two-way inductive charging
On Dec. 5, 2019, Apple submitted to the U.S. Patent and Trademark Office a filing for Inductive Charging Between Electronic Devices. This is actually only an update to a filing made in July of 2018 with the same name. And the company first floated the idea back 2015.

Still, it demonstrates that Apple continued actively researching building two-way inductive charging into future MacBook, iPad and iPhone models as recently as last winter.

It's not efficient and will significantly tax a 'Books battery.

But it could be handy in a pinch, and I'd be all for it if it could charge a Watch on the go.
