No seriously, I always get blank stares when I ask people, I’ve called them wall chargers or power bricks, my friend called them plug chargers, my fiancee calls them dongles. What do you call these around your house, like when you’re asking someone if they’ve seen any (______)'s
Power brick, power adapter, or USB charger are what come to mind for me.
I gotta say I disagree heavily with your fiancee on dongles. IMO dongles are adapters for data of some kind, not just power from the wall. But to each their own I guess.
The first time I heard the term dongle it was for the little adapter that connected to a PCMCIA card and I gave my buddy shit for using the term because I thought it sounded dumb. Then, on a trip to the local computer store an employee used the same term for the piece and I got to feel like the dumb one. Good times.
