Its an external battery. It lets you charge your ipod/smart phone/camera on the go. And depending on the size you buy, you can charge your device from dead to full charge, six whole times. So glad I discovered this.
See here on amazon

I thought you were going to say Google Glass.

Now that would be a waste of money.

It's a good idea, there are a lot of places where something like that would come in handy... airports especially

don't say that the reviews don't reckon it breaks easily, maybe that was just yours.
i chose mine to have an average capacity so it isnt so bulky, it about the same size as my ipod

Always wondered why I never seemed to see product like this, seemed an obvious thing to capitalize on

Well mine was cheap and I expected it to be a bit crappy. It's still useful thoughon train journeys etc
