Negative Positive
Title: Pretty much useless
Review: Generally, it and its wall wart just adds useless clutter. Doesn't hold much charge (might double the life of the average cell phone). Three or four times as large and heavy as the average cell phone. Not much in the way of uses: most of the time, you're going to be near an electric socket, a usb port or a car's cigarette lighter recepticle, so might as well just get the appropriate wires.
