A:AnswerIn regards to efficiency, all our PowerCores burn 30-40% of their power when they are charging other devices. So the PowerCore III 20K has 20,000mah of power, but the power left for charing your device is in fact 12,000 - 14,000mah.
Since your device has a battery capacity of 1810 mah, it should be able to charge 6-7 times with that PowerCore.
