Posted April 3 Hey guys, I daily a MacBook that is mostly connected to a monitor. It has power delivery and so I've got a cable that runs 60-90W to my Mac. I also have an ethernet cable that runs into the MacBook through a dongle. The dongle in question is some basic amazon one for 14-20€. I don't know much about how electricity works, hence being cautious plugging my power from the monitor into the dongle and running everything from 1 cable into my port. Do you think this is OK and I shouldn't worry? Or am I right being cautious? Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
Posted April 3 It's safe but it won't work as you expect, the dongle's input is only for power, it won't be able to pass the display data up to the monitor.

Posted April 3 USB-C's designed so anything that can be plugged to anything else is always safe, at worst it doesn't do anything. Would need something to be actually designed wrong / misusing connectors for something else for it not to be.

Just to give you a bit of context, why it would be safe to do that. USB power delivery never just applies a lot of "power" to the connector. Instead a small and safe amount, that any device that supports the USB spec can handle, is applied and then the device supplying the power and the one receiving the power have a short talk about how much "power" they actually support. As long as you don't buy a super shady power supply or hack one together yourself, you don't have to worry about it! Link to comment Share on other sites More sharing options...
