Plug in the microusb and check the current, then plug in the pogo cable and check the current. Then subtract the two.

Similiar to the moderm gas vehicle, power is drawn from the battery, it's replaced by the charger which is supplied by the 2A power supply or AC wall unit.
I don't have my POGO charger yet but noone has compared the USB and POGO charging rate at below a battery voltage of 4.2V to show the real maximum difference. It's been mentioned that the charging circuit is maxed at 2.0A, so anyone that's getting a larger PS isn't going to gain anything.
In Ohm's Law, I=current, V=volts and R=resistance.
