And you don’t want to rely on a converter for your hairdryer, etc. (anything with a motor and/or heating element) because they never work reliably and always wind up frying your appliance. If you can’t function without your curling iron, buy a cheap 220V one when you arrive.
For outlet adaptors, I love this universal type:

Plenty of inputs for USBs (of both types), plus a spot for a regular plug. And easier to organize than a bunch of different country/region-specific adaptors.
Personally I don't like the universal adapters since they are kind of bulky, but I understand the appeal. I might go with one by OREI, that's a brand that's been around a long time- I remember buying adapters of theirs 20 years ago. I am loathe to buy anything electrical by a brand I don't know
The other thing is that this "universal" adapter understandably doesn't have the very unusual type J plug that's somehow only in use in Switzerland. Now, a "euro" plug (type C) seems like it will generally work in Switzerland, but if you are plugging anything in that needs grounding, you don't have that with the type C plug. Won't be an issue for most things, but if using higher powered devices, I'd like a grounded connection for safety.
I bought a set of these for the UK and EU a long time ago, I like how small.and solid they are.

You can buy a 4 pack of each and still cheaper than one of the universal adapters. Maybe split with a friend.
