I wanted something portable that would recharge my Sansa 260 MP3 player. This item didn't meet my expectations. I discovered that I had to update the firmware for my player before I could even use the product. Once that was done and I connect the player to the charger, nothing happened. There is an indicator light which should have come on when charging. NO LIGHT. I contacted the company's customer service. The rep said that I could send it to them for an exchange. NOT WORTH IT. I needed this for a trip and couldn't wait. I wouldn't recommend this product!
