Cost to charge a mobile phone?

[MJDale]

I have a Nokia mobile phone. can someone tell me how much it costs (or at least how long it will take to use a unit of electricity to charge it? If it helps it has the following data on the charger unit: Input - 120mA 50 - 60 Hz Output - 5.3 V 500 mA Many Thanks

if you leave the charger plugged in and charging for around 34 3/4 hours it would use one unit of electricty - for my provider, thats around 6p

if you want the math, i think it goes like this. current * voltage = watts or i *v = p so .12 amps * 240v = 28.8 watts in on hour one unit of electricity is 1000 watts so multiply 28.8 watts by 34.75 hours and you get near enough 1000 watts. I think thats right anyway - hope it helps
