Does the HDTV power this device? How is it powered if not?

the converter comes with a USB power cord. I was using the converter with my computer to an old TV I do not have an HDTV. I tried the converter with and without the USB power supply to my computer and the converter worked either way. so I do not know exactly how it will work with it HDTD I did not even have to use the HDMI cable with my old TV I use the old fashioned RCA cables

But if you have an HDTV i don't know why you need this device. Are you sure you don't need the RCA to HDMI convertor?? It is the same company but it is a different part number. These units only convert one way not both so you need to buy the proper part # for your application.

I'm guessing the devices you're connected to powers it. I didn't have to plug the converter seperately so through the hdmi and RCA cables, it gets its power.

It comes with a power converter, and uses a power port on the side of the unit. Everything's included.

It comes with a mini USB power cable and can be powered from a TV USB port or a standard USB wall plug. Note that the device has a mini USB connection not the Micro USB connection that most newer devices and cell phones have.

no, it's power is initialized via the display port of the console. WARNING : this device when used with my wii did upscale to 480 P , but it caused screen tearing, this product unless it has been revised, did NOT work for me. =( , i got bc i didn't have a component in on my tv, so i tried this product so i could us HDMI , but it cause video issues like screen tearing. i recommend going with something different.

NO, it works just the other way around. You feed it with a VGA signal and it returns an HDMI signal.

I don't know about the TV question, but it can be plugged into an electrical outlet.

It comes with a power transformer for 110v 60hz power. The device does work, though it slightly alters the color. I used it for my RCA Cable box and only noticed it when on the menu.

The USB powers the unit (it has no batteries or adapter). What you have identified as the "headphone input" feeds the audio to the TV.

Power is not needed for MOST devices, but some need external power. Most satellite receivers or BluRay players will power the unit by themselves, but there's no way a small tablet can. The USB port is for use with those devices, so you can provide extra power to make up for what the HDMI source lacks.

No it uses a cable wire to hook up. You hook your cable box to it and your tv. We have HD tv.

no. It plugs directly into the tv with HDMI. And plugs into usb for power, depending on the tv. Put a wireless keyboard and mouse with it and it IS a computer.

The TV requires a 12v DC power source and it comes with a 110 volt (House current) converter that converts your house power down to the 12vDC. Watts is the amount of electricity this unit draws.

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

It is powered through the HDMI port and does not need to be plugged into other power

This device does not require a power adapter. The limited power that it consumes is delivered via the HDMI input.

It doesn't require power, so long as your input device provides power. Which assuming it's a TV, 99% of them do, the DC power unit can be found pretty much anywhere, just make sure you get the right wattage/voltage.

No its powered all the time. Has a surge protector too. I have two and will be getting more.

I ended up not using this device. The device cam e less power supply. I tried to contact the manufacturer to no avail. After may efforts they were to send a power supply but I got another unit instead. As I remember all inputs were hdmi. I hope this helps. I would not do any business with this company. They are also off shore. Good Luck Howard

Does not need external power supply BUT if your HDMI cords are the longer variety it will definitely need externaml power.
