The key here folks is that you are on an aircraft which has limited ability to provide unlimited 110V (amperage) power to each seat. In my experience, the maximum draw the outlet will allow is 75 to 80 watts (depends on the aircraft). If your device tries to draw more, the outlet automatically shuts down. Dell computers provides two different power converters, one at 130 watts, one at 80 watts, just for this reason.

Perhaps the provider of your equipment provides a power supply that draws 80 watts or less.
