Who his PC not only for charging an MP3 player wants to run (in my Philips GoGear) or eg on holiday has no notebook / netbook case, can not avoid a mains charger. One acquires the charger from the manufacturer of its MP3 player, you pay many times over the charger from PDAShop. And it need not be. The power supply of PDAShop touches his valent, is not overly warm during charging and appears after the device battery is charged, turn off (is cool). On the charger nothing wobbles, the processing is stable and the device does without hesitation his service. So highly recommended!
