Power requirements (nominal and peak) of LTE base HAT and Quectel EG-25G

Can someone from Sixfab please indicate the power requirements for the base HAT? I have found a Quectel HW design reference that indicates the typical/max peak current requirements of the power supply need to be 1.8 A / 2.0 A, but I can find no information about about the base hat current draw save for random comments on this forum that it is “very low”.

My experience thus far is not great as my pi occasionally locks up due to what I can only imagine is a 5v brownout. I can only avoid it by shedding my other USB devices, which I do need. I’m trying to make an informed decision about how to address the problem and could really use this information.
