I was going to say it's your power supply but you figured that out already.

I would skip those USB phone chargers, get something like this and solder a USB connector on it.

Sure they make larger. If you are powering off the USB there is a max output of I think 1.5amps from all the usb put together.

Here's an 8amp 5v

Pair it with a barrel adapter and you are good to go.
