It depends on the model of the plane that you will fly in. Some of them have outlets, but only in the front of the plane. Some of them have outlets on every 3-5 seats, and some of them may not have outlets at all unless it is for the flight attendants to plug in a coffee pot or something. Usually only first class gets the outlets, it is just one of those incentives to pay a lot of money for a first class ticket.
When electrical outlets get old they tend to chip and crack. Also in older outlets the socket gets loose and the plug will not stay in the outlet.
No it's not!
no
Yes, no problem.
Some do and some don't.
Maybe...... as long as they have the same outlets/plug-ins.
watch for plug outlets i guess
Don't use a plugin that allows you to use more that two outlets
A normal extension cord has a plug on it that is the same as any other plug.
Some airplanes do. See the related link on Continental Airlines, that I've provided. I'm not sure about other airlines. Some of the planes provide electric outlets which require an adapter. Years ago, I remember most planes had an outlet in the lavatory, which I believe was just for electric shavers, as I think the power source was not stable enough to run electronic devices.
Just plug in all of the light sets in to the outlets on the provided extension cord.
In a room, the maximum distance between duplex outlets is usually 12 feet. Too much distance between outlets can make it difficult to plug in all of the necessary electrical devices in a room.
