Query: The Chromecast dongle does get a little warm to the touch after hours of use but the converter is barely noticeable so I'm guessing I haven't overpowered it , which was my concern when I switched usb cables I'm giving the device 4 stars instead of 5 because I'm not sure why the provided usb cable didn't quite work for me.
