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
As it says on the device, power adapter. But if you wanted to be more specific, you could call it a USB power adapter.
Wall charger should also get the message across.
Take your fiancée to the hospital & check for stroke. Dongles…are something entirely different. Always.
Power Adapter is too broad.
If someone asked me for one I wouldn’t know what they wanted. It could be an international adapter, or a DC power supply, or one of these things.
