What I'm Doing
I have a laptop and I am looking to get a portable screen for my laptop.
Some of them have separate video and power connectors, but others give power and video over a single USB 3.0 cable. I really don't want to power a second monitor from my laptop, because that will really drain my laptop's battery. Instead I would like to power it from a battery pack.
Product / Hardware Recommendation Needed
I was thinking that some sort of USB Y shaped cable would do the trick. Then I could plug it from my laptop (male data) AND batterypack/wall (male power) TO my portable monitor (data + power)
