Connecting TB3 to multiple power sources

[ofarlig]

I am getting the new 13" MBP and I will also get an eGPU just to test some stuff with. I then wondered something, how does the MBP handle multiple connected thunderbolt cables all being able to deliver power? I am looking at the Razer Core X which can deliver up to 100W of power, and I also have a USB-C dock I use for my peripherals which can deliver up to 80W.

I am guessing the MBP won't fry itself if I connect it to both of them at the same time but where does it draw the power from? Is it the first one connected? The last one connected? A little bit from both?

Anyone know how they handle scenarios like this?

If you connect multiple power sources, the MacBook will choose the best-suited one to charge from. Apple doesn't say how the 'best-suited' one is determined, but it will probably pick the highest wattage.

Ahh, interesting, might have to test it out when I get it then. Thanks for the answer.

Usually it will use the first one that was connected
