Thank you all for the comments. So I'm looking at slim desktop style travel chargers, trying to stay away from unknown brands. Here's an Anker USB C Charger, 543 Charger (65W II), PIQ 3.0 & GaN 4-Port Slim Fast Wall Charger, with Dual USB C Ports and Dual USB A Ports. It seems reasonably compact.

For the same price, more or less, I could get a Statechi, and get 100w, but is this a good brand. At least with Anker I know it's good quality.

I like the suggestion of replacing the cord with a EU Type 2 cord, but I could also simply use an adapter. Then I'd be able to also use it if I needed to in a US hotel or airport, should I get stuck somewhere on way there or home.
