I've done quite a few posts on this blog about travel adapters for electronics. For a start, I've covered the Travelon adapter and converter, the three-piece unit from Sima Products, and the 150-country adapter with USB port available from a catalog company.
But there are more, many more, so here's a full rundown I did for a product review website: the best travel electrical adapters.
The way that site works, there are 5 "best of the best" and 5 "best of the rest," but of course it really depends on your individual needs. If you are just carrying a laptop with a built-in voltage converter, a plug set is fine. If you are carrying five devices of varying wattage, then you need a voltage converter that can handle all that.
Look through the options and see what makes sense. Or just leave it all at home and act like a backpacker from 15 or 20 years ago: no gadgets, no plugs, no worries.
Yeah I know, if nothing else, there's your digital camera...
