Ah, thanks for clearing it up! Another question: I saw many international flights feature a VOD system with a LCD screen that is playing some movies on the back of every seat. Does the power to drive the system enough to charge a laptop then?
- gvb 16y agoI am not familiar with the VOD systems, but I really doubt it. A typical laptop brick is rated at 70W and it probably pulls close to that with a discharged battery. I would expect the VOD display system to be running around 10W. My guess is 1W lost in a 90% efficiency power supply, 5W for the display, 1W for an ARM processor, the rest for the video decoder chip and miscellaneous support chips.
