About LinkBacksMaybe 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'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 ?

100 batts --- don't we all. Sometimes it seems that way. Originally Posted by ratsacker

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

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
