What is the 60W MagSafe output voltage?
What is the 60W MagSafe output voltage when it is disconnected from the computer?
MacBook, MacBook Pro 및 MacBook Air에 사용되는 AC 전원 어댑터. 잡아당길 때 안전하게 분리되는 자가-정렬 자성 커넥터를 사용합니다. 1 세대 (2006-2012) MagSafe 충전기는 약간 두꺼운 L 자형 커넥터가 있습니다. 45 W, 60 W 및 85 W 버전으로 제공됩니다.
While not easy to see you'll find the side that is opposite the plug pins (where you grab it) in light gray print the specs of the unit. It should be marked 18.5 Volts.

Given the pin sizes I don't recommend trying to use a meter probe as you are more likely going to short it out. I have a spare DC In-board which I wired up with test leads when I need to check a power adapter.
