Power Draw of Dev Kit and Nreal Light

Hello,

I am trying to power the Dev Kit Computer and the Nreal Light for 6 hrs. I am trying to figure out how much power to spec for a USB Battery Bank. I know it depends on how bright, how much tracking, cameras in use, etc but looking for a rough estimate. Any guesses on the power needed to run for 6 hours?

The Dev Kit FAQ webpage (https://developer.nreal.ai/faq) says

" Q: How long could the battery support?

A: The duration of use may vary depending on specific user scenario (the power of the computing unit is 7000 mAh)."

Does this refer to the power draw of the Dev Kit Computer or is this the capacity of the BBattery in the Dev Kit Computer?
