In Monte Carlo, they use Type C, E, and F plugs and sockets. The mains voltage is 230 V, and the frequency is 50 Hz.
So, you’ll definitely need a travel adaptor in Monte Carlo. Their plugs and sockets aren’t the same as our Type G back in the UK.

Sockets in Monte Carlo
The plug types you’ll find in Monte Carlo are Type C, E, and F plugs and sockets.
Type C

Type C sockets have two round pins and no grounding. Unlike Type G, they take a slimmer plug without an earth pin or fuse.
Type E

Type E sockets have two round pins and a hole for the socket’s earth pin. UK Type G plugs do not fit into Type E sockets.
Type F

Type F sockets have two round pins with two earth clips on the side. UK Type G plugs do not fit into Type F sockets.

Realised abroad that you’ve left your adaptor behind? You’ll often find them in airports and shops nearby. Still, carrying your own is cheaper and more reliable.
Monte Carlo is often included in trips to France and Italy. It’s smart to check the plug info — even small countries might have slight variations.
Do You Need a Voltage Converter?
A voltage converter only helps if the supply is different. In Monte Carlo the mains voltage lines up with the UK, so there’s no need.
Do check the voltage label on your kit before you travel. If it states ‘100–240 V, 50/60 Hz’, you’re safe to use it without a converter.
