The Guide to Capacity and Efficiency of Portable Chargers

Conversion Rate: 16000*3.6/10200*5.1>90%. This is really misleading. Actually, 10200mAh refers to the capacity that it can charge the cell phone at, and the cell phone battery is normally 3.6V too, so, simple math here: Total rated energy: 16000mAH * 3.6V = 57.6Wh. Energy Usable: 10200mAh * 3.6V = 36.72Wh.

Battery Capacity

Battery capacity. It is a measure of a battery''s ability to store or deliver electrical energy and it is expressed in units of ampere hours (Ah). An ampere hour is equal to a discharge of 1 A over 1 h. For example, a battery that discharges 15 A to a load in 10 h is described as having delivered 150 Ah.

Energy Storage Capacity

Thermal capacitance is connected to the energy storage capacity and assumes no energy losses. It is defined as the heat flow necessary to change the temperature rate of a medium by one unit in one second: (5.124) C t h = q ( t) d θ ( t) d t = d Q ( t) d t d θ ( t) d t = d Q d θ. The SI unit for thermal capacitance is N-m-K −1 (or J-K −1 ).
