Is it safe to use the mac's cable for an airport express? When you pull the power plug off the airport express, a connector appears, similar to the connector on the mac's power brick. These connect perfectly, but I want to be sure: is it safe to use a mac's cable to power an airport express?
I often use the smaller Airport cable to power the Mac power adapter without having a ground and you can safely do the opposite as long as you get a firm connection and support the AirPort hardware if the plug extends lower than the bottom of the device.
