One  20 000 mAh Battery pack for charging mobile phone or whatever which can be charged from USB...
Two old laptop battery packs.
The battery from laptop have 3.6V. (the red color)
The battery in the original pack have 3.9V
So i decided to keep them divided using one switch to switch between them...

One microUSB input for charging. 2USB for output 2.1A 5V.
One screw connector to connect wires in case no connector available. Here is output of 5V (the same as USB) and 3.9V or 3.6V directly from batteries.

Here is the detail of switch between 3.6V or 3.9V. Both will go to the charging controller so USB voltage is always stable...
