I tried using my pixel slate's charger (which I think is ~45W) with my hub but CC just boot loops. I'm guessing my charger couldn't supply enough power. Does anybody have a power brick suggestion? Preferably microcenter or anything else not Amazon. Thank you!
I had this when using my Chromebook charger. Try plugging the HUB to the Chromecast first, then the power supply to the HUB. If that doesn't work try connecting the power supply to the HUB, then the HUB to the Chromecast.
Since then I got this one , no boot loop when plugging everything to the TV. But when restarting from Settings > System > Restart, it does a few boot loops before powering on.
