International charging

When I travel overseas I carry a plug adapter for each country, my usual Anker USB-C charger, and the necessary Anker USB cables since many of my devices are not USB-C. For example, my Garmin InReach and my Anker battery pack take micro-USB, my iPad mini takes USB-C, and my Apple iPhone takes Apple Lightning.

Not sure what your device options but I’d suggest something along these lines along with a simple plug adapter https://www.amazon.com/Anker-Charger-Compact-Foldable-Included/dp/B0B2MM3252?ref_=ast_sto_dp&th=1&psc=1

The adapter will be almost as big as the charger https://www.amazon.com/BESTEK-Grounded-Universal-Adapter-Ireland/dp/B00RBFK5AC?ref_=ast_sto_dp&th=1&psc=1

I’m with Bruce.  I do a ton of traveling all over the world, and I take adapters for all of it.  Yeah, my phone charges with a usb port, but not every country and/or hotel has those.  Scotland should be fine, if you take one of the UK adapters–just live with the fact that the outlets and plugs there are massive. So are the adapters.

You can buy chargers which have a set of  slide off prongs of 3 types – US, UK and Euro.

I bought this one last year. It’s very good. Click the photo
