Hi, I see that both of them are used in Greece. What is the best one to buy thanks
I believe type f will be much more convenient
I always carry some very slim type C adapters, they seem to fit nearly all sockets of the two pin type. Type F, I believe, is now standard in Greece, so you couldn't go too wrong having those, but for the small size and cost of a type C or two, I'd bring them along.
For things like phones, computers etc , even a curling iron, this is what we used on Greece
Had no problems
Electrical outlets in Greece are type F. So, type F and type C adapters (without the ground pin) will work in all outlets
Since adapaters only change the plug end configuration make sure your appliances are dual voltage, 110-240v, if you use them. If not, you'll need to include a voltage converter/transformer to protect them.
