As said before, it depends upon what Apple devices. 2.1? 2.4? USB-C, whatever that is.
My Apple stuff: a very old iPod Touch, a new iPod Touch, a very old iPad, a new iPad, an iPhone SE. All are actively used when I travel. Each has its own charging requirements.
On battery power: 3 cigarette-lighter style 12V outlets in coach and in a pinch the 12V in the dash (always live, but it works off the truck battery, so best not to use it unless the engine is running). I have been using Belkin adapters (car chargers) for years. Not finding exact same thing on Amazon today. Other vendors may have them.
On shore power: 2 110V outlets in coach. Plug strip. Or keep on using those 12V outlets as above.
Watch out for "car charger" type adapters which label their USB ports as "Apple" and "Android." Huh? I want to know - 1.5? 2.1? 2.4?
I hope this info helps you.
