Apple 45W MagSafe 2 Power Adapter for MacBook Air

  • Overview

    The 45W MagSafe 2 Power Adapter features a magnetic DC connector so if someone should trip over it, the cord disconnects harmlessly and your MacBook Air stays put safely. It also 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 lights up; an amber light lets you know that your notebook 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 you an even easier and more compact way to travel.

    Designed to be the perfect travelling companion, the adapter 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 featuring MagSafe 2 power port.

      I feel like Apple have bent me over the table and...

      What a joke... 4th one in two years (two for my macbook pro.... two for my air). The magsafe cable connector is a flimsy piece of junk. As others have said - it What a joke... 4th one in two years (two for my macbook pro.... two for my air). The magsafe cable connector is a flimsy piece of junk. As others have said - it splits and frays really easily. Honestly, this charger is sooo poor, I'm contemplating going back to Windows. I'm sick and tired of spending £65 on these useless pieces of #### There, I said it... this charger is ####! At least make it so the flimsy end can be detached and easily replaced. What a waste... I have four broken charger units in a box.... and about to order another. £325 on chargers.... Apple, you (draw into the mouth by contracting the muscles of the lips and mouth to make a partial vacuum) - your censorbot won't let me say that you [kcus] I'm not swallowing this any more... thats it... yes - you've just lost a customer because of your useless piece of #### charger... oh, I also LOVE ANDROID!!!!!! does that hurt you? well, I bet it doesn't hurt as much as the pain you've caused my wallet!!!!

      Flimsy at best

      Second power pack now that's frayed at the joint with the magnetic head. And yet I'm expected to pay for a replacement each time!

      Terrible product, Apple seems to ignore these indicting reviews

I am now on my third adapter in 18 months. How Apple can make such brilliant computers, but then power them with such a shoddy power accessory is beyond me. They clearly are not reading these reviews - every single adapter has terrible ratings and all for the same reasons. Apple: get your act together and stop producing junk and charging loyal customers huge amounts for a basic necessity.

      Poor Quality

      The charger cable frayed at the base - not acceptable as it has been well looked after.

      Bad quality

      I've spent more on replacing magsafe(s) than on the macbook itself.

      BOOK A GENIUS APPOINTMENT

The person I spoke with was very helpful and sorted the problem very quickly! This was at the Southampton store. I advise to book an appointment before purchasing the charger! :)
