Bests & Worsts Reviews from Amazon

I was able to use this on my 4K Fire TV on 2 different TV’s without any major issues. I’m even able to run this off the USB port of my Visio sound bar. So yes, this works exactly as it’s supposed to and then some. To all those who keep giving it 1star reviews saying that “the cable doesn’t work”, stop blaming the cable because of your lack of understanding. All this cable does, and all it’s designed to do, is transmit power from Source (TV USB port) to Device (Fire/Chromecast/Roku stick). It isn’t a power supply, it doesn’t create power out of thin air. If your TV doesn’t have a powered USB port, or if it doesn’t supply enough power, there isn’t a cable in the planet that will fix that. Contrary to belief, not every USB port on a TV supplies power for an external device. Majority of them are input-only, meaning they are for cameras, camcorders, or USB memory sticks. And not every powered USB port is at the 2.0 standard or above. So if your streaming stick doesn’t work with this (not enough power, incompatible, etc), guess what sunshine? It’s your TV that’s the problem, not the cable.
