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.

      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.

      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!!!!

      Frail cable

      Same problem as everyone else. The cable frays at both ends leaving the wires exposed, leading to it not charging properly as well as being a electrical hazard. Same problem as everyone else. The cable frays at both ends leaving the wires exposed, leading to it not charging properly as well as being a electrical hazard. Yes apple is known for having expensive prices, but £79 for a charger is obscene especially when it breaks so easily and fast.

Seriously I have seen the way some MAC's are treated and have to say if you treat your MAC like garbage then do not expect it to last! Thanks ... satisfied customer.

The previous one lasted less than a year. the rubber at the end of the cable (laptop side) keeps fraying eventually causing it to fail this is just through everyday use that you would expect from a laptop charger. it is also massively over priced at £79. for this price you should expect it to last.
