Yep, I also have used the outlets in our old DC-10's and B727's to run my laptop with no ill effects.... .. .And I have seen the cleaners try to use a standard vaccum in those outlets once or twice too.. .. .The bloody thing spooled up like a JT8D-217 going to takeoff power for about 10 seconds till she smoked her guts out... . .. .Pretty funny stuff for sure! Although the cleaners would beg to differ...
