Using this to power a cooling fand and Works great.
It does not allow you to leave the light on after the tv is turned off.
I use it as a switch for my USB powered LED van lights.
This switch works great.
Absolute junk....bought another brand of usb on/off which worked great on my headset...wanted to buy another one but unfortunately they were sold out so I bought this....doesn't work at all...always off.
So it will only work for usb charging/power.
When I saw the advertisement of this cable with the explanation“No need to pull the cable to restart or reboot your devices, just press the button to turn on and off” I thought I was solving my problem.Imagine my surprise when I connected it to my computer and did not see any reaction.
I was looking for a switch that a device could communicate through so that flipping the switch would be like plugging in or unplugging a usb device from my computer.
This is power only.
