I'm just sorting through all of my electronics and accessories that I'll be packing for Italy next month and I have what I believe to be a universal AC adapter plug for my camera's battery that I'll be packing with me. I've attached a photo within this message; it has all the relevant input/output voltage info.

It comes with about a half dozen different electrical adapters, but the stupid thing is that none of them are labeled; at least not for laymans like myself.

They're identified by letters rather than countries/region:
A-4, G-1 (1x JC A-2 and 1x JC A-4), K-1 (not sure why I have two of these that appear identical), N-1, U-1, and one for N. America which I use regularly.

To simplify things, I've attached a photo of all of the adapters and I would greatly appreciate it if you could take a quick look and help me to identify the correct one to use in Italy.

I have a feeling that it's one of the two G-1 adapters, but I'd like to be absolutely certain and I'd also like to know whether I need to pack the A-2 or A-4 version (or both).

Thanks so much for taking the time to look at the photos and help me to figure this out; I really appreciate it!

Ciao,
Oliver
