I asked a similar question yrs back and was given a formula to figure out approx run times based on draw, but I can't find the thread
If anyone can tell me what the approx run time would be for say a 10,000 mAh battery pack w/1A and 2A USB outs. (I assume if I was using both at once the run time is just cut in half since both devices would be exactly the same)
This is what the manual say...
Power
Power Supply (rated)
3.6V DC (battery pack), 5.3V DC (compact power adapter)
Power Consumption
2.7W (SP mode, AF on, LCD normal brightness)
CA-110 Compact Power Adapter
Power Supply: 1--=240V AC, 50/60 Hz
Rated Output/Consumption: 5.3V DC, 1.5A / 17VA (100V) - 23VA (240V)
BP-709 Battery Pack
Lithium Ion
Rated Voltage: 3.6V DC
Capacity: 920mAh (typical) 3.3Wh/895 mAH (minimum)
THE POWER BANK WOULD BE RUN INTO THE "CA-110 COMPACT POWER ADAPTER" JACKusing this cable

Huge Thanks
