    For the past few days, I've been needing to jiggle my MagSafe 2 power cord (45w) in the outlet to get my Macbook Air to not just read it but do so for more than 3-4 seconds.
    Today it seems to have reached its end.

    Now This power chord is actually a combination of the original adapter that came with the Macbook when I received it and the duck head from a faulty new one my stepfather bought me last year. Faulty as in, it overheats causing my earbuds to buzz and tonight it seemingly caused my outlet to shut itself off which is a safety feature the outlets we have in our house have.

    I just noticed a small tear in the cord right underneath the adapter most likely the result of my having to give it a good yank a few times when moving the laptop between my living room, my bedroom and my class. So perhaps this caused the problem, but if not I'd first like some confirmation that the power cord does need replacing, then I'd like recommendations as to a reliable seller outside Apple itself that will have it for cheaper than $80.

    Macbook Air 2012 approx. five years old.

    Certainly, not ALL outside Apple are knock offs, are they?

    My 2013 MA power cord had its magsafe cord split near near the input into my MA. You can get original Apple magsafe 45 watt on eBay for around $26.00. I ordered one, and it arrived perfectly! There are a lot of 3rd party magsafe replacements, but I prefer original Apple parts.

    We sell genuine and compatible macsafe chargers.

    our compatibles are almost as expensive as the real ones.

    They have genuine apple leads and magsafe tip but not the block.

    I have one for my 2009 macbook but I use the genuine more.

    I noticed the ground pin in the teardown of the genuine.

    the lead from wall to my genuine charger does not have any earth/ground connection.

    I have both the wire and block type mains slot in tip.
    My wire has no ground, not looked at the block plug as don't use it.

    OWC ( sells Apple power adapters for less than list. For all of my family MB* I get the 85W supply. My daughter loves this for her 2011 MBA - "charges faster" - and it doesn't seem to have any adverse effects. I did recently replace the battery, and the old one showed 1000+ cycles. YMMV.

    The duckheads on chargers have design issues for a free global recall and replace by Apple.
    For now, use the longer cable until you get it replaced for free at your local apple repair shop.

    The issue is when some twits take the adapter out, while leaving the duckhead in the socket.
