Thank you for contacting the Intel community.
In this case, we don’t guarantee that a stick will work with other components like this because Intel has not validated, so because of that there is no battery brand or model that we can say is compatible, but we have seen positive feedback in other posts, you can check here:
I encourage other community members to share their experience with us if it is possible.

I have to ask what may be a dumb question: What good is a battery-powered ICS when the TV/Monitor is NOT powered?
I use the stick for MS Office files and carry a portable monitor. Had to get the stick so that I could travel through Trump-banned airports. I stick the monitor in my luggage, but don't want to lose my PC, so I carry that in my briefcase. A battery would help me to avoid losing work due to the occasional lapses in power in poorer nations. Make sense?
I've ordered one from Amazon with AC out and will let you know if it works ok.
I have information that is useful for me. I am dealing with online software. There are impressive things from this forum. If you look at my design in this design I expect you to support it.
