Is-it possible to power by Thunderbolt 3 ?

Hi !

I'm looking for a backup solution while traveling and I was wondering if some of the NUCs can be powered by the Thunderbolt 3 port ?

Thanks !

Actually none, but I'm planning to buy one if they can be powered by USB or Thunderbolt.

How many volts and amps do you expect to get from TB3?

No idea, as some have Thunderbolt 3 I thought I could use the Apple USB-C 87W power adapter .

Here are a list of nucs and product specifications.

https://www.intel.com/content/www/us/en/support/articles/000005545/mini-pcs.html https://www.intel.com/content/www/us/en/support/articles/000005545/mini-pcs.html

This is but one example - Look on page 52 here: https://www.intel.com/content/dam/support/us/en/documents/mini-pcs/nuc-kits/NUC8i7HVK_TechProdSpec.p... https://www.intel.com/content/dam/support/us/en/documents/mini-pcs/nuc-kits/NUC8i7HVK_TechProdSpec.p...

Here is another: Look on page 55: https://www.intel.com/content/dam/support/us/en/documents/boardsandkits/NUC7i5BN_NUC7i7BN_TechProdSp... https://www.intel.com/content/dam/support/us/en/documents/boardsandkits/NUC7i5BN_NUC7i7BN_TechProdSp...

As you can see, the voltage and amps vary.

Regarding your apple usb-c charger, this is what I can find:

Input: 100-240V~1.5A 50-60Hz

Output: 20.2V==4.3A or 9V==3A (USB PO) or 5.2V==2.4A

So, it does not provide adequate power, not to mention rigging a proper power connector.

Personally, I would abandon this effort. If you have to carry a power brick, carry the brick that came with the nuc.

Al, doesn't matter which one, this is not something that's supported on any NUCs at present.

Stating that slightly better,

  1. The NUC products do not have support for being powered via the USB-C connector. That is, they do not have support for the (USB-C-based) "Universal Charging Port" specification.
  2. The NUC products do not have support for powering devices requiring more than 15W. That is, they do not support the (optional) USB-C Power Delivery 2.0 Specification.

See https://en.wikipedia.org/wiki/USB-C USB-C - Wikipedia for more information.
