electricity is an iPhone application that monitors the electricity while it's connected to a power outlet via a USB power adapter.

it's really simple: connect the iphone/ipod to the charger. start the app. put the phone down with the sceen facing downwards. that's it!

if the power goes out an acoustic alarm will sound. the iPhone will also vibrate.

it is very useful in situations where you need to be notified in the middle of the night of a power failure. Like if you have a burglar alarm, an aquarium, big freezer, heater, etc.
