This converter is easy to set up and does provide the advertised 720/1080 resolutions. The power requirement however are nowhere to be found on the instructions manual nor on the packaging. I had to come back to the product page to see that it need a 5V supply, but even then I wasn't sure about the amps. I was able to get it working with a regular 1A adapter, so thankfully not a lot of power needed and easy to get one of those. Given that this is an analog signal originally, you will have to set the appropriate format or framing on your device (4:3) to avoid the letterbox in some content.
