Customer Reviews

Long trip
I was skeptical at first when I got this becuase of the back and forth reviews I have read. I recently used this on a long road trip to power my Zune 120 and it worked great. It kept the player fully charged at all times. As a test on the way back I let the player battery almost die out and then plugged it into this. The player recharged within an hour (wasn't watching my watch...). I am going to test it on other products to see what happens.

Worked great
I bought this to charge my Blackberry 8120 and my Sansa MP3 player. I have had no problems with it. It has worked exactly as it stated. I wouldn't hesitate to buy another if this one ever breaks.

Some Products Require Their Own Branded Chargers
Not really a rating, but some informational guidance. Some products require their own branded chargers. They actually have a special circuit inside their chargers that the product looks for. If it doesn't find it, it refuses to charge. I know my Blackberry is such a product. Only works with a RIM/Blackberry charger. But my Garmin GPS will run from any USB cable power source I have given it. If your product starts to charge then stops, the problem is in your product, not in the charger.
