    The one I have will work well as a power supply, but will NOT charge the battery on my Zen Micro Photo.

    I have way too many USB devices to charge and this device seemed like a great way to cut down on the number of charging blocks. Since I have a second generation iPod Touch, the first review put my mind at ease that it would charge all of my devices. First week it was great, it charged everything without a problem. Phone, touch, iPod, Clip, no problem. One week later, the green status LED isn’t steady anymore and when I plug in my Touch it keeps turning on during charge. It’s like the charger is pulsing instead of a steady charge. At ~$25 and from Griffin, I expected that it would last for more than a week! Griffin obviously has quality issues with this device and I would recommend you looking for another charger.

    Great product allowing you to charge almost any device with the same cord. Plug up to two USB cords into it and charge two or more devices at the same time. I own two. They work flawlessly. Use this with iGo brand tips and cables not the iGo AC od DC adapters. You can also find a DC to USB power plug for your vehicle. Never buy another cell phone car charger again for $30. Just buy a new iGo tip for $7 and keep using this or the car charger with the new tip!

    This bare bones version requires your own sync cord to charge, do not expect it to include anything but the block.

    Also charges Sony MP3 but does not charge Sony PRS505.

    I was hesitant to buy any adapter for iPod other than the one sold by Apple because I thought it may damage my player. But after reading the reviews I decided to buy this and well I am happy with my purchase and saved 50% over the original Apple adapter. I have a Classic 6G and a Nano 5G. And they charge just fine with no worries. I would recommend this to everyone. Plus it has 110-240V voltage range so it can be used outside of US when you are travelling.
