Something doesn't quite add up to me. I want to interpret the yellow W as instantaneous power in watts and the large blue voltage and red current as instantaneous measurements as well. (What is happening right now). With that voltage and current the watts should be non-zero ~0.047W or so.

But, just so we can play with some numbers.....
I will assume for now that 77552 mAh is the amount of current pulled along with time, basically average milliAmps*hours.

Divide by the number of hours to get the average number of milliAmps over that time period.
Divide again by 1000 if you want to turn it into average Amps used over that time.
This average includes time it is charging and time it is not so could vary wildly from the peak power. (Lake with an average depth of 6 inches...)

If you want to turn it into power used over that time you multiply by the voltage to get milliwatt-hours.

Assume 33 days and 5 hours, ignoring the 23 minutes for now.
Total number hours = 33*24+5= 797 hours.

milliamps = (77552 mAh / 797 h) = 97.3 mA
or 0.0973 Amps

For average energy used over that time we could just multiply the milliAmp hours * the average voltage. If I assume the average voltage was somewhere between the current voltage (5.24V5) and max voltage (5.47V)...say 5.3V, then the average power in milliwatts is
77552 mAH * 5.3V = 411025.6 mWH (milliwatt-hours) = 411 watt-hours = 0.411 killiwatt hours
Probably around a nickel's worth of electricity at rates around here.

The other thing I thought of that the mAH could possibly be is sort of an amount of charge charged to a battery. If it zeroes when you put the phone on and then starts counting up, that might be it. If it keeps incrementing from where it is then it is more the average I was thinking above.

Based on the peak power numbers and the fact it is supposed to be a 5V charger my guess is it is probably using between 5-7 watts most of the time it is charging and based on the average numbers it is averaging around 0.5 watts for cumulative charge and non-charge time together.

Hopefully I did not embarrass myself with a huge mistake being tired at the end of a long day.
Is that kinda what you were after? Old guys with old cars gotta stick together.

Cool gadget anyway.
