If you’re ever going overseas, you’ll need an adapter converter for any electronics, probably your iphone/ipad/laptop. I would highly recommend a travel adapter converter that includes some USB charging ports. Most hotels nowadays will have these things, but most airports don’t and probably most airbnbs don’t either.
There are other kinds. The ones you want to avoid are the ones with many parts. I was embarrassed when I was in Singapore and had a travel adapter that didn’t fit! One end was literally made to fit in another and it didn’t fit! This one is one piece, so besides the cords, there’s not much that can break. Additionally, there’s a USB-C port. Many tablets and phones now are exclusively usb-c, so this one works great for that use case!
The adapter/charger I got is the Achoro one. I don’t know if there’s a named brand one of these, but this one has served me well for a few uses. I plug this one into the wall where I get a nightlight builtin and charge my iphone/ipad/watch/laptop overnight at the same time with it. https://usgiftgiant.com/achoro-4-usb-ports-travel-adapter/
For just $20, I would say this is a great deal. I would recommend putting one in the suitcase and one in the backpack just in case – these things can easily be lost and unless you’re in Asia, they’re pretty expensive to buy when you need them immediately.
