    This seems to be the one thing that people do not mention. They say rechargeables save money in the long run, especially with high drain devices, but how much does it add to the electric bill for every four AA charge?

    Our electric bill is less than $100 every month, and we have two Kindle Fires, two iPhones, an iPod Touch, and a Android. Plus my MBP. A pack of 8 AA batteries is like $5-10 depending on brand. It has to be a big savings really if we can power our entire house for less than $100 a month.

    And yeah, it DOES save money. Especially when you're talking about digital cameras, which can go through 8 of those in one day. Our rechargeables don't add much to our bill.

    Im pretty sure its a few cents per month. Our electric bill per month is less than $40 per month.

    An iPhone 5 costs $0.41USD per year to charge (for the average person). So probably in the area of under a cent.

    The average cost of consuming a kiloWatt per hour in the US is around $0.12 (according to NPR).

    A charging iPod/iPhone consumes 5W per hour. Bear in mind, 1 kiloWatt (kW) is 1000W. In simple terms you are not even consuming 1% of a kilowatt which means your cost is less than 1% of that $0.12.

    In other words your iPhone or iPod consumes out of your pocket a mere $0.0012 per hour of charging (assuming 1% usage which no iOS device consumes ever).
