Yes the velcro straps

I tend to bring twisty ties with me too and as said earlier I may need to strip them to make the plug prongs "thicker"

Now that I think of it, perhaps I shall take a couple of mostly used eu and us charge heads and drip some solder on em and buff it out with fine sand paper. This should result in a conductive yet relatively save solution. It could fatten up the ends of things used. I will just have to make sure to always have enough of the right fat ones laying around for whatever destination
