Ok so I have not been able to find this specific question on the interwebs.
I am looking for a USB hub that will power the pi and a few other things. I'm not concerned about the over all power rating of the hub but rather the individual ports. I have found a few with 2.4 amp ports but I have noticed in the past the rpi 3b runs smoother on 3.0 amp ports. My question is. Can I simply make a cable that connects 2 of the ports from the USB hub to the one micro USB port on the pi. I know the voltage will stay at 5v. In theory I should get roughly up to 6 amps. I know it wouldn't be good to let the pi pull 6 amps so maybe a fuse for safety but is there anything I'm missing here?
