I have not migrated to USB C yet, still using older tech. I prefer to have a charger that can supply everything, even if that means more cords.
But since the trip that supplied the above photo, I have become self sufficient on my dyno powered USB charger, have not had to plug into any outlets on my last tour. And the tour before that, was self sufficient for the last half of that tour once I realized that one of my cables had high resistance to I quit using that particular cable. That bad cable cut my wattage flow in half into my powerbank.
If you are using USB C for the higher wattage, you can still get chargers that have several ports on the charger.
If you are also carrying a power bank(s), if that powerbank also works in a pass through mode, you can charge that powerbank plus a device that is plugged into that powerbank at the same time to charge both.
If this is for your planned trip of many many weeks on a bike, get the right stuff before you start. On one bike tour a decade ago, I brought a 3 into on adapter for the outlet so that in one port on that outlet I could plug in three devices. That came in handy several times when several of us at the campground had to share one outlet.
My sister is going to Europe in a few weeks, a few days ago I gave her an EU plug outlet adapter that would allow her to plug her laptop, her phone and her apple watch battery charger all into one outlet for her trip.
