Exactly what it says on the tin.
While active it emulates a charged UPS for any equipment that requires one, draining power directly from your internal batteries.
You can already sync with power armor with the power armor interface bionic.

That’s a cool idea. I like the image of pulling back a flap of skin on your chest or wherever just to reveal a hidden flash drive, or some futuristic plug for power.
