Information re: battery in the Prime Go

Hi all,

I am curious about the voltage and mAh / Wh capacity of the Li-Ion battery in this unit, as well as the power draw of the Prime Go itself.

I understand the estimated runtime to be about 4 hours. How does the charging functionality work? Does it draw power from the DC input? Does it have a PCB that cuts off charging if it’s it’s plugged in long enough?

Thanks in advance.
