Hi,
I am ready to buy a travel adapter for Italy (determined that I don't need a converter), however I'm now noticing there are 3-prong (grounded) vs 2-prong (ungrounded) adapters. Not sure which I should get (will be using for camera charger, cell-phone charger and travel hairdryer).
Can anyone clarify? How can I tell which I will need?
Thanks!

You run into a lot of old wiring/outlets in Italy so you might encounter both types depending on hotel. I only take the 2 prong, but you might want to take one of each. Of course you wouldn't be able to use the 3 prong in an outlet that only has 2 holes.

I've only used 2-prong adapters (I didn't know that there were 3-prong adapters). Take a 2-prong or if you feel more comfortable with a 3-prong then take both.

Hi MT,

You only need a 3-prong adapter if you have a 3-prong wire to plug in.

A 2-prong adapter will fit a 3-prong outlet.

Not Italy...but I ran into situation in London this year where my 2-prong would not go into the 3-prong socket. I had to go out and buy an adapter.

I didn't think there were ANY 2-prong outlets in the UK

My work around was to use the two pin socket in the washromm to plug my stuff into. I made the mistake of planning a last minute trip and just grabbing a Walmart universal adapter. I am now wiser

Thanks!

This might better explain power options in Italy. This post has pictures and information. As noted, if your item does not require "grounding" than the 2-prong will work. The hair dryer could be a challenge.... Read this: http://www.roninrome.com/2009/03/08/power-in-italy/

Thanks Ron- that was a great article! All of my appliance are just 2-pronged so they shouldn't require "grounding", correct? And, I bought a dual-voltage hair dryer (again with only 2 prongs).

You will not find plug adapters mislabeled as converters nor will you find converters mislabeled as plug adapters in the US. Sets will be listed as converter and adapter set. Many of the newer power converters will be 0-2000 watts with auto switch so you don't have to worry about switching high/low.
