I haven't been on that aircraft, only the EK -200 and -300ER.
Could I suggest that you buy a decent adaptor offering UK to US and Euro plugs, as you should be safe if you have that.
My experience with the EK -200 is that the sockets don't like power supplies drawing 100w and tend to trip out.
Don't know if that is the case with the -200ER, but if you have a 65w power supply, it might be the safe choice to take.
