(Multipack) Firestick TV Stick USB Power Cable for Fire TV Stick (Amazon Fire TV not Included) (1 Pack) by fireCable

This item works perfectly with the 4k fire tv. I have even realized that by using this cord the 4k fire tv device does not get as hot as it did with the ac adapter plugged into it. Worth buying and trusting this device.

The media could not be loaded.  The cable works great and eliminates the need for a power outlet! I was a little skeptical at first as I'm not "technology savy" but the setup was simple and performed as promised. I would definitely recommend

I found that the power cable works, but there is a time delay when turning on the FireTV stick. when I hooked the USB cable to the TV's USB. When I used the original power cord, there is a noticeable difference in the startup of the FireTV stick to the main menu. If you can live with the delay, then this can work for you. For me- it's in a drawer

With my new tv purchase I was shooting for a neat installation I have even used a cable organizer receptical. This usb power keeps your dongle and the power cord in the little space where the inputs are.

did not work

It does not keep the device powered on when the TV is turned off. So every time the TV is turned on, you have to wait for the device to boot. As soon as you plug the device in, it tells you that this adapter does not provide enough power.

I thought it might not work at first because other firestick cable reviews in amazon says they do not work. Still gave it a try since price isn’t bad anyway. It works!

I like not having to use wall outlet however I found out I could have adjusted adapter that came with firestick with same results. I didn't need topurchase this.
