At some point my older Mac charger that I was using for traveling died, so as a replacement I got a few of these styles of adapters: https://www.amazon.com/dp/B08YS7QHM9 (not the exact one I have - but you get the idea). I pair it with one of these: https://www.anker.com/products/a2687-anker-prime-charger-160... which is tiny for the amount of power it can output, which has been enough to cover both me and my wife while we travel. Many US plug chargers allow their pins to fold in, including this one, which makes for a fantastically compact setup when paired with that style of adapter.

Depending on where we are going and what we are doing, I also bring this thing: https://www.amazon.com/dp/B08YDPB8RZ which is kind of an extension cord + USB charger + all-in-one converter as well. The plug is at a right angle and very flat, so it can fit behind furniture and such that straight cables can't.
