Yes, but most homes don't have extra 220v outlets except for the ones provided for the specific appliances that need them.
So if you want to plug in a device like this "tinybox" at home, it's going to be a lot easier to find two separate 110v outlets on different circuits than to have a new 220v circuit added, or to unplug your stove every time you want to use it.
I don't know what adversarial relationship you have with electricians, but adding more 220v outlets is absolutely feasible. Usually takes an electrician a day of work.
