And what's Brit about scoundrels, swag, and mains adapters...?
True, we have way too many 'scoundrels' "over here!" "Swag" seems rather dated, no matter what its 'nationality.' "Mains," however, is definitely not 'American.'
First, we don't refer to the in-home 120V AC lines as "mains." And secondly, if we need to attach some kind of 'voltage/current' converter, especially for these small appliances, they are called by their highly technical term: "Wall Warts"
