Odyessy x86 board power consumption?

I cannot find any information on the power consumption of the Odyessy X86 boards specifically the X86J4125800. I need to power it with a battery; an average power or max and min would be great.

Thanks

In one YouTube review, they measured it around 4 watts at idle and 15 watts under maximum load. I’m sure it will vary depending on how many drives and/or devices you have connected but his review was with just an M.2 SSD if I recall correctly.
