My family is going to the EU this summer and we need USB chargers AND a socket for a hair dryer. Instead of buying EU electronics we have confirmed that all our devices are rated for 100-240V (it says small print next to the plug) and all we need are some fun European pins. These little pass-through adapters are very basic, they fit snugly etc. I have other EU chargers and they look the same. We'll know for sure later this summer, but I'm pretty sure they'll work great. Update: Have used these in many places for a few weeks, they are fantastic. That's all I take for the EU Continental Adapter.
