How does the power work? Do you have to plug the USB into a PC, while you are connected to the video input on a TV

we only use on a computer to view pictures from a SD card from a wild game camera. We have never connected to a TV

I use it from my directv to a computer monitor and I do not use external power. It works great.

I'm looking at ir. It is a diagnostic port only, you cannot show video from a USB drive, but you should be able to get power from it. Good luck.

This does not require any power. Its plug and play. One end goes into your Samsung smartphone and the other is for HDMI to your HDTV. There is another port on the back that is female connector, which accepts input that is the exact same plug that you're plugging into your Samsung smartphone. Not sure what this is for. Possibly a separate device. I have never used it. After i received this device from Amazon, 2 days later, i lost my Samsung Galaxy smartphone. So i only used this thing one time.

There is a cable that comes with it micro usb to usb that will plunder in a usb port on the tv. If usb port isn't available then there is power adapter that will plug into a local power source 120 v

Yep, it needs power. However, it can take power through USB as well as AC. Most TV's and HDMI devices it would plug into have USB ports already, and it includes a short USB cable. All of them I have in place now (4) use the USB supplied power.

I'm using mine with my BMPC 4K and a Marshall HDMI monitor... It does require USB power though.

Turn it on , Use the cable sent within the box , plug the USB to your computer and the other end into the line in/5v slot .This worked for me ,

The usb is for power. The hdmi is on the opposite end from the audio video connections.

This will only work from PC to TV if your PC has a micro USB out. Odds are it does not.

I use it on a 7" TV works great. It has a cable TV plug on it. Not a USB . It also has to be plugged into an electric outlet. Hope this helps.

The quick answer is "I don't know", but I searched the Internet on your behalf, it would appear that different manufacturers provide USB port for different reasons but none provide a composite video/audio output that can be input to your television

Lisa, don't buy it. It is not what it seems. It works less than Ok on a computer, but for a TV set, it doesn't work. It receives it's power from a USB source and my USB port on my TV did not do it.

How do you power your TV? Mine is not powered from USB ports, neither is my Refrigerator or my Toaster.

Only a USB connector is noted for an input. There is notation for audio/video cable and jacks but those are probably for TV outputs. So... probably not!
