Switching a 220v outlet to a 110v outlets

I have this home kit model at my house. They are very comfortable, especially if you order some electrical devices from other countries(I’m traveling a lot, so I got devices from different countries, and all of them have different types of plugs). Still, this home kit is very uncomfortable for putting in baggage, and traveling with such a large device may cause different questions on the border, so while I’m traveling, I prefer using the smart plug. This device is very comfortable, especially if you visit many countries and must keep all your devices(laptop/phone) online.
