Video Review: Mobile Spark External Battery

Rating: 9 out of 10
Pros: The power just goes on and on and on and on.  I could not get it to die. Reasonable price and free shipping. Includes many adapters to power all your gadgets and there will be a Motorola Droid adapter soon.
Cons: It is not a case style battery so you have to kind of hold it while it is charging.  The glossy finish is a fingerprint magnet.
Overall: The Mobile Spark External backup battery is one of the longest lasting external battery that I have tested to date.  On one charge we power from totally dead mind you, 2 iPhones, 3 iPod Touches, 1 Nintendo DSi and then we played a dead DSi for about a half hour before this thing died.  A few things I would like to see be implemented is a carrying case and some sort of automatic shutoff if the unit is not being utilized for more than say 10 minutes.

You can purchase the Mobile Spark from Amazon for $57.75 and free shipping. Click here to see check it out.
