Re power converters - if you look at most electronics lately (laptop power supply, camera battery chargers, etc) - look at the input on the power cord - if it says 100-240 volt input, then you don't need a voltage converter, you just need the plug adapter. I just take a couple plug adapters and a 3 or 6 outlet plug to plug into that - then all my electronics can go into charge on that. I still carry a voltage converter, but very rarely do I actually have anything that I plug in that needs conversion.
