This charger does the job exactly as it is intended to do. You plug in the Flip camera (less clumsy with a USB extension cord) and it charges the camera battery. What I don't understand is, why can this cannot be done with any USB power adapter? Perhaps there are some good reasons for that, but it means that I will have to keep track of my my Flip USB adapter (or buy one for the house, one for the car and one for each of my three workplaces) rather than pick up the nearest generic USB adapter. Interestingly, the Flip Mino does not seem to have this problem. So, a great little adapter/charger, as a frequent international traveler I am glad it handles international voltages, but I am not quite sure why it is necessary.
