I used this adapter to setup the YubiKey 5C that I carry around as a backup on my keychain. It's all just USB, there's nothing special, so form-factor adapters will work just fine.
Ahh my bad I forgot to add that I bought a female USB C to male USB A adapter this is the link 👇

Can you update your post (or drop it in the comments) to include what specific devices you're carrying?
Phone (what generation)?
Personal Locator Device (which one)?
Power Bank (which one)?
Anything else (like a headlamp or earbuds)?
Because the way to approach it is backtracking "from the device(s) to the wall", and then let that inform what charger is best for you.
Because without that, you'll get loads of generic advice for a specific question.
I think two single port chargers are lighter, but a single charger is more efficient.
This isn't always the case anymore. We're now on "3rd generation charging tech". What you' referring to was more common in 1st and 2nd generation tech.
What you want to look for is:
What is the output max total AND the total output per port?
That will tell you if the charger will fulfill your power needs. You can get something like this, which is terrific...but it may be "in excess to requirement"...or not. I really just depends on what you need and your price point.
This one may be better since you won't have a laptop.
So start with your power needs and work backwards.
If a two port charger breaks I can no longer charge. If one of the single port chargers breaks I still have a backup.
Realistically, unless you abuse your charger, this won't happen. Someone will always have one you can borrow temporarily. But it may not be as fast as you like, and you may have to wait.
The real benefit of having two outputs is you can charge both your phone and your powerbank at the same time.
Get a good charger, and you can charge 10,000mAh in <5h.
But do you want to wait 5h until you can start charging your phone too?
Of course not. That's why they now make dual port USB-C output like this.
What makes the most sense for towns/hostels?
Generally speaking, you want "as much juice as you can get in a short period of time". This is balanced against weight.
If you dig through boards on r/pacificcresttrail, you'll find a number of times the question has come up in the semi-recent past. Sort by date.
Or I (or someone else) can try to summarize once you list your power needs.
The most common thing is you're fighting for available plugs. If you have only outlet, you want to make the most of it -- ergo, either:
1) You charge one device at a time and wait, or 2) You have dual ports and can top-off two devices at once <or> share with a friend. (It's also a good way to make friends. :) )
Q: What about cables?
A: Everything is moving towards USB-C. Why? Because it is superior tech and can carry more power more quickly than USB-A. Having a USB-C>USB-A charging adapter (like this) isn't a bad idea these days.
Q: Isn't USB-A still everywhere?
Yes. But if you have adapters, it's not as critical. Also, USB-A are the ones that tend to break more since they're not reversible.
NOTE: This is extemporaneous commenting, and others are welcome to chime in. Lots of ways to skin this cat. But it always starts with the individual's power needs, then you work backwards.
