Ever so slightly off the point. On some aircraft (in this case a 777) there are little plugs in the loos which can be used for electric razors. Please dont think you can plug in your mobile phone to charge if you have an adapter. And if you are that stupid please dont leave it there unsupervised!!!
Some numpty did this once upon a time and when I came to do my toilet checks (apparently only 12 minutes or so after he plugged it in) I found the adapter had melted into the plug and was nicely smoldering... would have been no time before the facial tissues which are stowed directly above the plug would have ignited and then we would have had a lovely little situation over the Atlantic Ocean in the middle of the night!
