HDMI provides about 50mA minimum. USB can provide up to 500mA or 900mA depending on USB 2 or 3. I am not 100% sure what the power requirements for a Chromecast

I am not 100% sure what the power requirements for a Chromecast are, I'm 100% sure it is more then 50mA.
If you are plugging in your Chromecast to your TV without the USB and it is working it's because you have a MHL-HDMI that provides up to 900mA of power.
