Actual capacity 20000mAh, advertised capacity 32000mAh
32000mAh sounds too good to be true. Interestingly the manual doesn’t mention capacity, but the charge time is 5V/3A 6H good enough to charge up to 24000mAh battery (in reality much less because of charging efficiency; 5V*3A*6H/3.7V=24.3Ah). It does not look right, so I decided to test this battery on Rigol DL3021A. The results are inline with the change time: 74.241wh / 3.7v (Lithium-ion nominal voltage) = 20Ah or 20000mAh. The other way to calculate capacity is to convert 5051mAh @14.8v to 3.7v (Lithium-ion nominal voltage), or simply multiply by a number of cells: 5051mAh*4.
