How do I run a PS4 on a Battery without a power supply?

I am trying to make a Playstation 4 portable with a PS4 slim and I am trying to figure out how to power it with a battery without a ps4 power supply. I know most battery output DC power but the one I am looking at the outlet does AC power. So I am guessing I will either have to get a converter to make it DC powered instead or find out if I can remove the converter from the battery so it will be DC powered. Just wondering if this is what I will have to do and if so what converter would you recommend or if not what would I do.

This is the battery I am looking at:

And this is what it looks like so far.
