I am wondering how I could put two USB battery packs in parallel together in order to increase their amperage/current.
I do not want to tamper with the Battery packs, as breaking them apart and soldering a new connector is out of the picture for the scope of the project, so I was wondering if I could do the following to accomplish the task:
Attach USB cables to each of the two exactly same battery packs, cut off the positive and negative ends of the USB exposed cable and solder positive to positive, negative to negative. I would then solder the input red/black wires of the item I want to power to the now negative-negative positive-positive ends of their respective USB wires.
Would this work? Can a quality USB cable be able to transfer 4.8 amps?
