You can use the hairdryer with just an adapter plug if you turn the switch to the 220 position. Do not use your converter with it. The hairdryer will get twice as hot on 220 volts but the voltage switch will prevent you from turning it on high. Low or medium on 220 will the the same as high on 110. Yes, most camera chargers take 110 to 220 or 240 volts. You don’t need to worry about wattage for these items. Yes, unless it’s a dual voltage one. My suggestion would be to buy a dual voltage straightener (Conair and Vidal Sassoon have dual voltage lines) and skip the converter. True — check the box on the power cord for inputs (should accept 220 volts and 50 Megahertz) to be sure. The 50 cycle current in Europe as opposed to 60 cycle in the US may mean the cooling fan runs slower. I would unplug it if the netbook if it seems to be getting too hot.

Final answer.
1. This is far too much electronic and electrical gear. You have seriously overpacked and will regret it after just a few days.
2. If you get a dual voltage straightener (or better yet leave the straightener at home) you do not need a converter and can avoid the crapshoot of frying either the straightener or the converter.
3. There’s an article on electricity under “packing” on the “travel tips” tab.

Might I recommend a hat? Compatible even in places without electricity.

And BTW, the netbook is seriously overkill unless you are traveling for some employment-related reason.

As I re-read the original post, I see it’s possible that you think you need a converter for your electronic and dual-voltage stuff. You do not. Do not use the converter with anything except the straightener.

Thanks for all your help, since I’m not truly “backpacking,” I’m not worried about how much I’m bringing. This is what I usually bring on trips. I was just worried since last time I thought I had bought an adapter/converter…. turns out I only got an adapter…bye bye hair straightener! haha

it might be worth reading this travel tip that oldlady posted about electricity…
