Is that this device is defective, unfortunately I have only noticed on vacation when I wanted to invite my new MP3 player with it. Since I had no computer on site to load the MP3 player, I had to buy a new charger expensive. The return home was no problem luckily as the 4 weeks after purchase were not over yet. ----- Supplement in November 2013: Although I have gechickt the defective charger back and the complete reimbursement had got it, I got from HandyNow sent a replacement connector. The enclosed letter was clear that this new connector is a revised quality, and he would be free for me. The time was a pleasant surprise. But since I only hear holiday music on the MP3 player, I have connected to the new plug only once to load, and this time it's managed.
