I have a MacBook 12" that I connect to my Dell 4K screen with a Google USB-C to DisplayPort cable (this one)

It works perfect. But now I am not able to charge the MacBook while connected because the cable takes the only USB-C port available.

So I need some kind of USB-C or a adapter that puts voltage on the cable back to the MacBook. Both I did not find yet.

Take a look at these two multiport adapters from Apple:

There's no technical reason why third parties won't come out with adapters since all of this is standard. USB C charging, video formats, the connector type are all non-proprietary. Only time will tell if businesses invest in making these products, but Apple's two adapters work very well for the use case you describe.

Also keep an eye out for cables and monitors that send the required USB charging current over USB-C most higher quality displays should soon be able to charge your computer like Apple's previous generation displays now that the proprietary charge connection is gone from the MacBook (and others).

    Great answer - forgive the large answer, but I wanted to chime in with my MacBook experience and research. If you want to revert - feel free and if someone could ping me so I could add a second answer, that would be great.

  • Thanks for the answer. These adapters will unfortunately will not deliver the bandwidth required for getting the most out of the Dell 4K screen. So my question is more about a known USB hub that allows for putting power on the cable as well. Commented Feb 15, 2016 at 20:50
  • @bmike If OP states that this answer is not correct, shouldn't it be deleted?
