Our used X rental had a very small fuse in cig lighter and the "power point" connection. Turns out Cruise America puts tiny fuses because if they didn't renters would try to power up a small city. I'm willing to bet Cruise America is not the only RV rental outfit that puts in small fuses. Can't remember the size of fuse but do remember blowing the fuse on a small invertor. But 2 phones and a gps works fine on ours.
Those converters you plug in to the wall to make US type electric stuff work in Europe (at least in Germany) are available lots of places and not much money. Something like a CVS type store.
(other stuff that might help) The problem I had was my credit card (without a chip) wouldn't work in there ATM machines. As matter of fact their ATM ate my card. Turns out their ATM's require a chip in the card. That was about 7 years ago.
Maybe your card already has a chip in it. Technology catching up, if not call and find out if there is anything you need to do to use your card in other country's.
That was the trip we discovered that we will always have more than one credit card account from different institutions and will bring a card from each and will have a little more cash than we think we will need, just in case.
