Camping in France and wanting to charge phone and batteries

In Paris at least, people who want to charge phones just go to a café and plug their phone into a wall socket.

Many campsites have electrical sockets to hook up to the caravan. You'll probably find someone willing to 'lend' a socket for a few hours or so or you could rent one yourself!

Don't worry, even if you're on a tent site the camping reception will often let you charge your phone at their office, the camping restaurant or a comparable place. Alternatively, if you go to an internet cafe to check your email while travelling, they never mind if you plug in wile you are doing so.

You won't have any problem with that, don't worry.

If you have a car, you can always get a car charger for your mobile phone, I think it's the same standard charger around the world?
