batteries - Can you combine the outputs of two ports on a USB Battery Pack?

I have a quick question: I have a USB battery pack, and I want to use that battery pack to power a little side project that I have.

Currently, this side project takes an input of 5V 4.8A, and I have seen USB Battery Packs that output 5V 2.4A on one port, and 5V 2.4A on another port for a total of 5V 4.8A.

I was wondering, if I ran two USB cables with their heads plugged into a 5V 2.4A (per port, 2 ports) USB battery pack, exposed the proper wires, would I be able to combine the red wire of one USB cable with the red wire of another USB cable and black wire of one USB cable and the black wire from the other USB cable to create an output of 5V 4.8A? sort of like what is happening below in which many wires are soldered together, and then connected into a single red

Otherwise, could I split the ends of the wire that extends from the side project (the item I am trying to power) into two, so: split the end of the red wire in half and the end of the black wire in half. Then, attach a red/black wire to each half respectively and in the end have two red wires flow into the 1 red input wire needed to charge?
