I’m using a PowerPort+ 5 Ports USB-C with a MacBook Pro 13" on the USB-C port plus an iPhone and an Apple Watch on the regular ports. This seems to have been working fine for a few weeks and it kept my MacBook topped up just fine with just the 30W.
But now it seems that the USB-C port isn’t providing any power any more, while the regular ports do just fine.
My question is, wether a MacBook Pro might overload the adapter as I remember that I only saw the smaller MacBook mentioned in the specifications.
Somehow was was of the impression, that with USB-C the two ends negotiate how much power can be supplied and as long as it contains a 20V supply it would just charge slower or temporarily not fully cover what the computer draws.
Is that assumption wrong and did I maybe blow the adapter by using it with the MacBook Pro?
