How Much Is AGL Getting?
Maybe there's a simple formula, maybe there's a nerdy guy who can answer this nerdy question...
So how much power does charging an 18650 with 2000mah's suck up off the power grid? Out of curiosity I want to calculate how much each charge or tens of charges is costing me in power bills.
Weird question? Probably, but I'm a curious guy.

You can get those little plug meters that tell you.

you'd need to factor in the loss from the charger. something about stepping down from 240v to 5?v, and powering the PCB and any indicator leds as well.
guessing it would be in tenths of cents ?

I was about to say the same.
It is about bugger all of almost nothing or silver change quarterly unless one has 100 batts charging at all times

100 batts --- don't we all. Sometimes it seems that way.

just done a test on the Aspire subohm bat
2.9w so at 25c/kWh its going to cost me all of $1.00 dollar annually if it was on charge for 4 hrs everyday
EDIT: That was for one battery but if you go through 4 batteries a day its going to be a huge 4 bucks annually
You will have to skip one of your minimum of chips to pay off your debt

3.85V (storage voltage) x 2200mAh (capacity in Ah) = 8470mWh = 8.47Wh to charge @ 100% efficiency
Assume 75% efficiency and fully charging 1 a day, every day = 8.47 x 365 / 0.75 = 4122 Wh = 4.12 kWh @ 25c / kWh = $1.03 PA
