Sally, I googled and found these answers:


"The Nook has a switchable power supply. You will need an adapter, though, to fit the outlet and it should work fine. You will, not, however, be able to order books in Europe. "

"Can I charge my iphone overseas?
Yes, you only need an adapter. The white box on the iphone wall charger has a built-in converter. You can read the very fine print on the box: 100-240V - Europe is 220V so you are fine. "

And for your Acer netbook:

"All netbooks today will accept "dual" voltages (European and U.S.). The power supply for my netbook (Acer) has a grounded plug (the one with the round pin in addition to the two flat blades).
My plug adapter is narrow and fits over the blades with clearance for the grounding pin (which doesn't connect to anything).
check for the Input Voltage ratings on the Charger / Power Supply for your Netbook (the ratings will probably be listed in VERY fine print - use a magnifying glass if necessary).

If the ratings state 100-240 VAC, 50/60 Hz then all you'll need is an inexpensive Plug Adapter (the style for continental Europe has two round pins). If the ratings are as stated above, you will NOT need a Voltage Converter. "

Here are some cheap 3 prong adapters, maybe one of them will work for you.
