一老外是这么说的：
My biggest concern was that this device would be running constantly 24/7 as I started to fish a power cord through the wall to supply power to the unit. Then a light bulb went off in my head. I took the supplied mini to full USB cable, plugged the mini side in the unit and the full side in my TV's USB port.

Now when my TV's is turned on the unit gets it power and boots up. When I turn the power to my TV off, the unit powers down. No need for the power supply.

另一个用户：
Have this hooked up to my tv with a 3tb drive attached and it makes a great media center pc. I have the mini USB port hooked to the tv USB so when tv is off so is the unit. Haven't seen any heating or freeze problems at all. Like the idea that it plays any video file format. Works great.

我的理解是连OTG转成USB插到电视的USB口上
就可以实现电视供电了
开电视棒子就亮，关电视就灭

电视不再身边
晚上回去试试。

我就是这样弄的，有人建议别这样，万一烧毁就那啥了！
老老实实的用了电源。
