I don't want a video adaptor but I do want to be able to plug in my MB to power while simultaneously connecting to a device by USB. My ideal adaptor would be USB-C -> Dual USB-C w/power passthrough, but I'd settle for an adaptor like the digital av multiport w/o the video (i.e., USB-C -> (1)USB-C & (1)USB). Any word on whether such an adaptor yet exists? I assume it's only a matter of time. But I want it now!
