Just an update on my travels with the Pipamoka portable siphon-style brewer.
I recently forgot my mini coffee scale (17.5g seems about the sweet spot for this device) but since my Q2 grinder maxes out around 20g, it’s not a difficult eye-ball job. By packing the grinder into the pipamoka it makes for a very tight little package:

This is everything I need minus the beans. Unlike my aeropress, this brews into itself - an insulated travel mug. Dosing is also aided by the grounds puck that you basically fill maximally. I’ll still probably bring my scale if I remember next time, but no panics if the batteries run out.

I haven’t had any regrets since switching from the aeropress. I will comment that if throwing this in a carry-on, it could get flagged by TSA. Twice now they’ve done a bag search for not being able to identify what this is.
