This long power cord I use to power my projector over a distance of almost 10 meters. It runs in parallel with a high-quality HDMI cable in a 20 x 20 mm cable duct. Since too thick is not (even narrower than the HDMI), it could be embarrassed and well accommodate. So far there are no disturbances in the HDMI transmission of image and sound, the current one does not expect that anyway. By the white color it fälltt also vacancies on not particularly. I am very pleased with price and performance and can recommend the purchase.
