Chromecast with Google TV requires 5v 1.5a usb to power

by Cozmo85

So you can power it off your tv's usb port if it says it supports 1.5a or 1500mah or a higher number. If your tv only supports 1000mah or 1amp then you need to use the included brick. Most only support up to 1amp

Good to know. My Hisense is only 5v - 0.5A.

Most TV's only support 0.5 amp. So unless one has a rare high end tv its a no go.

Protip just use cable without data transmission. Work even with 0.5A
