Sorry eduard to upset you ..what I suggested is common sense to me and of course going around in an understated way will give you more natural pictures .
One way to ease your charging problems is to obtain before you leave a four way outlet with a short cable matched to your native countries plug and then purchase a European multi plug travel adaptor. You can then plug in your normal chargers and phones using there standard plugs. Most chargers are 110-240 and 240 is standard in Europe . You will not find 110v.
Good luck with the trip.
