Here is a demo video of monitoring the power going from as USB cable to my phone:
Here is a demo video of the power monitor showing the voltage/current within its own charging cable (whilst charging itself!):

After getting the Trinket, LCD, and INA219 to work on a bread board I drew up everything on Fritzing so I had a reference should anything go wrong whilst transferring onto a permanent proto-board.
I intentionally soldered on female pins so that:
1. All components could be easily replaced should they fail.
2. Components could be upgraded such as the LCD from size 16x2 to 20x4.
3. I could remove and use the components for other concurrent projects to save money.

Modifying the Arduino code and moving around some input pins to get the LCD pins and INA219 to fit nicely onto the Trinket.

I got the INA219 to give a Serial Readout of using an Arduino UNO thanks to the Adafruit Tutorial.
I also got the UNO to readout the current and voltage onto a 16x2 LCD.
