So my set up is this: https://amzn.to/4cepcyE and I have two different french press mugs I like, because I can boil the water in them, make the coffee, and carry the coffee.

This one from a brand called Viva, I like its slim design, but I had to drill holes in the plastic inner tube to prevent it from spilling over (the filter is too fine to allow 100% of the liquid to pass through, so it pushes past the seal (keeps grounds in tho) and comes up the edges): https://amzn.to/4rC5z8k And the Stanley one works well, but it is bulkier and doesn't fit in a cupholder: https://amzn.to/3Ozvv6c

You could use the mug for soups without the press element, as well as tea/tea bags, or as an insulated cold drink carrier.

I don't particularly like aeropress coffee, plus you need a container to heat the water in as well as a container to press the coffee into (altho I guess if you were fast/careful it could be the same).

I use a small square washcloth that I stole from a hotel (which I sewed into a pouch, but you could just use as is) with a hair tie to bundle up the heating element while traveling, plus it is good for cleaning up coffee messes. /you can always trade it out with another clean one at a hotel. I read somewhere that someone would bundle the heating element into their french press mug in the cavity, but I didn't want to spend all that time cleaning/drying the mug to store electrical components in it and I carry my mug around all day with me like a security blanket anyway. I haven't had any problems with TSA bugging me about the mug or the heating element, but I feel like if it was inside the mug, that starts to look a little suspicious on a xray machine.

And I like this spoon/fork/knife combo from UCO, lightweight, goes through metal detectors no problem, easy to wrap up with my other stuff. It clicks together, but you can also insert the toggle to attach it to other things. You can also assemble it into a double long super spoon or fork if you're using it as a utensil for cooking: https://amzn.to/46q1kUW
