I bought my macbook air recently from the US, I need is the little component that goes into the wall socket (the UK 3-pin instead of the US 2-pin)

I don't need an extra power supply, but I do need the little component in the adapter which plugs into the wall to replace the US 2-pin component. I'm hoping that the UK component can be purchased on its own

Should I purchase the 45W MagSafe 2 Adapter for my 11" Air (2nd gen, 2011)?

The answers I'm reading are not too clear. I have the Mac Air 11" 2nd gen (mid 2011). I recently left my MagSafe Power Adapter at an airport and need a replacement. But upon discovering that Apple has just come out with a Mac Air 11" 3rd gen (mid 2012) and and with a slightly different power adapter, calling it the MagSafe 2, I'm left to ponder what should be a non-decision. Would I be better advised to purchase the MagSafe 2 even though my Mac Air is the previous year's?

I sort of liked my old MagSafe with the tiny cylinder-shaped plug that was shaped to look like part of the cable (it was practically a necessity with my 1st Mac Air from 2008 because the receptacle was toward the bottom of the machine instead of on the side). But the MagSafe 2 appears to use a less stylish, squarish magnetic connector that's similar in appearance to all of the MagSafe connectors that preceded the 1st Mac Air.

Is the MacSafe 2 the better bet for use with the preceding Mac Air (2nd gen 11", 2011)? Besides being smaller and employing a more conventional-looking connector, are there any substantial improvements and advantages to consider? Is it perhaps more rugged with a longer, more wrap-able cable?

what safeguards does the MagSafe 2 provide from hissing and sparking power sockets? Does it prevent any damaging voltage from reaching the laptop?

please tell me if there is a fuse built it the MagSafe 2 power adapter.
