[MacTUG] Using Thunderbolt Display to charge new macbook pro

[Donald Duff-McCracken]

That would sorta work Glenn, but I don’t think its gonna give the juice to run a macbook pro. It would be fine for lower power devices such as to charge a usb-C phone.

I think I am going to tell him just to buy a second power supply. Maybe in a few years USB-C will be everywhere! ;-)

Hi Don,

Not sure if there ever will be one as Apple isn’t likely to allow someone to use their MagSafe patent.

Below describes the situation and maybe offers you an option to try.

Such a product can not exist: Apple has patented MagSafe technology<https://www.google.com/patents/US7311526> and thus such a product would be illegal. Even if it were made, your MacBook would likely detect it as a fake charger and stop itself from charging like iOS devices do<https://www.imobie.com/support/fix-this-accessory-may-not-be-supported.htm>.
However, you can easily plug an inexpensive USB to USB-C cable into a standard USB port on the back of your Thunderbolt Display and charge your USB-C MacBook from there. Here's one such cable on Amazon for $11<http://rads.stackoverflow.com/amzn/click/B0119QMQ6O>.
This is a safer, simpler, more reliable, and less warranty-voiding way to charge your 2016 MacBook Pro directly from a monitor (like the Apple Cinema or Thunderbolt displays) without using up another outlet for your laptop power supply (or spending nearly $100 on a new power adapter and cable from Apple).
I have personally used the linked cable; it works just fine charging my usb-c devices.

It would be nice if there was a magsafe to usb-c adapter so that users can continue to use their Thunderbolt Display to charge their new macbook pro, but I cannot really see any anywhere. There is this critter on kickstarter, but a) it is not shipping yet and it seems sketchy, and b) but it will not mate to a real magsafe plug but just has “magsafe-like” functionality (it has round ends vs a magsafe’s more rectangular profile).

Has anyone seen any adapter out there to get juice from a magsafe power source to usb-C?
