Final Update: Turns out it was my charger all along . Here is what I ended up doing. From my Pi3 I run a DC Barrel Jack to Micro-USB B Male Connector (http://a.co/d/4yVdU3c) . Then from the barrel jack I have a normal power supply (http://a.co/d/7j0vMr3) . No voltage issues at all and everything seems fine.
