What is the difference between the 10.000 and the 20.000 mAH battery size stated on the box?

The physical battery in Boombox has a capacity of 10.000mAh @7.4V. This is the charged battery storage. When outputting ( so power from the battery is drawn ), it's using 3.7V, half the storage voltage, which will give you 74Wh - equivalent to a 20.000mAh battery with power stored at 3.7V.
