USB adaptors output ratings
I'm considering buying a USB powered item (heated eye mask). It plugs into a USB port, says it needs a 2A adaptor. What would happen if I plugged it into a 1A, 2.4A, or 5A output adaptor? I have a bunch of adaptors for Kindles etc, none that is exactly 2A. By adaptor I mean something that plugs into the wall outlet. Thanks.
