Apple 45W MagSafe Power Adapter for MacBook Air
The 45-Watt MagSafe Power Adapter for MacBook Air features a magnetic DC connector that ensures your power cable will disconnect if it experiences undue strain, and helps prevent fraying or weakening of the cables over time. In addition, the magnetic DC helps guide the plug into the system for a quick and secure connection.
When the connection is secure, an LED located at the head of the DC connector will light up; an amber light lets you know that your portable is charging, while a green light tells you that you have a full charge. An AC lead is provided with the adapter for maximum lead length, while the AC wall adapter (also provided) gives users an even easier and more compact way to travel.
Redesigned specifically for MacBook Air, the adapter is the perfect travelling companion. It has a clever design that allows the DC cable to be wound neatly around itself for easy cable storage.
This power adapter recharges the lithium polymer battery while the system is off, on, or in sleep mode. It also powers the system if you choose to operate without a battery.
Compatible only with MacBook Air with MagSafe Power Port.

Can Macbook 13" (c.2012) and MacBook Air 13# (c. 2011) use the same 60W Magsafe power adapter?

The MacBook Air comes with a 45W MagSafe power adapter and the 13-Inch MacBook from 2006-2009 and t The MacBook Air comes with a 45W MagSafe power adapter and the 13-Inch MacBook from 2006-2009 and the 13-Inch MacBook Pro use the 60W power adapter. If the 2012 MacBook Pro is the model without the Retina display (With the CD/DVD drive) then the 60W would work on both. If you were to use a 45W MagSafe power adapter on the MacBook Pro, then it can cause problems with the battery and main logic board which are hard and not cheap to fix. The 60W MagSafe power adapter should work fine on the MacBook Air as well as the MacBook Pro.

Short answer: No.
I have not seen any converter which can convert from the MagSa Short answer: No.
I have not seen any converter which can convert from the MagSafe 'magnetic head' to USB type-C head, therefore it can't be used with the newer Macbooks with USB C ports only.

Just use a 'tourists plug adaptor' and it will work fine. I lived in the US ten years ago and plugge Just use a 'tourists plug adaptor' and it will work fine. I lived in the US ten years ago and plugged my UK purchased Toshiba laptop into the mains using an ordinary travel adaptor that you get in an airport etc and it worked fine. I bought a Macbook Pro when I was out there - which is what I am typing on now and it plugs into the mains in the UK without any problems.
You don't know need a 'convertor' - just an 'adaptor' If you look on the 'white box' in the middle of the power cable, it actually says 100-240V and 50/60Hz. The supplied power cable does the necessary work for you.
So - I am using a US purchased MBP with the original US power adaptor and all I have is a £4.99 travel plug adaptor and it works just fine.
