Ehn....bad product. Got hot the first time I plugged it into a converter for my trip to Europe. Lasted one day and then blew up. I got one full charge out of it. Thankfully it was only $5+S/H, so I cant really complain. Still....it may work in the States as it is intended but if you are buying this for an unlocked phone to use across the pond....try finding the proper Euro version of it to the place you are going or dont expect much out of it. All of my other electronics worked fine in the converter.
