    stopped working

    I've got 3 of these and the one I use the most recently first became unreliable (had to jiggle it to get the light) and then stopped working entirely. The magsafe I power packs still work with the other converters, so I can only conclude that this converter has gone off. So, much as I hate to say it, spend an extra $10 an make sure that you have a backup!

    Rarely works - not recommended

    I have two Thunderbolt displays and a rMBP. I got one of these so I could use the charging cable on the displays - however despite the connector being firmly in place and providing power to the laptop, it won't charge the battery and the LED light on the charging cable does not light up. When using a CPU intensive app, it's actually possible to drain the battery of the laptop, forcing it into sleep mode.

    On rare occasions it works as you'd expect, the LED illuminates and the battery charges - but it's so hit or miss you could spend 30 minutes plugging and unplugging the cable before it eventually works properly. Not recommended.

    Works half the time

    This is a great idea except for two problems.
    1) It seldom works, so you gotta do a ridiculous amount of fiddling before it starts charging.
    2) The first problem is exacerbated by the fact that the light seldom comes on, so you never know if it works unless you switch on your laptop.

    The time needed to get your laptop charging is ridiculous.

    Product works great with appropriate expectations

    I am not sure what the negative reviews of this are for. It is a converter and it works great. It has a strong enough magnet to primarily remain with the cord. The light on the cord works fine when charging. That said it is a separate unit and if you expect it to be permanently attached it is not....so treat it with some care. If you understand that, it is a great alternative to buying a new power cord.

    Excellent Product

    I purchased a MBA and I have a 24 in Display and couldn't understand why the cable didn't fit. After checking online and reading some of the information provided on the Apple Site, I discovered the display had a Mag and the MBA was Mag2. The adapter allows me to keep my MBA power supply in my case and it has worked flawlessly. I think the people that are complaining should consider the cost of a new power supply vs $10.00!

    Pretty much never works.

    I have used multiple power adapters from my Macbook Pro to charge my Macbook Air with this adapter. It only works after having to fiddle with it over and over again. Then it has to sit perfectly still as any movement disturbs it. If you have it on a desk this shouldn't be a problem, but I typically use mine on the couch then it never works.

    very disappointing

    Does not charge all the time.

    It is necessary to wiggle and adjust the fitting of the magsafe. Very disappointing in apple, a company that usually produces the best hardware.

    I bought a 1000$ thunderbolt display with a 1800$ macbook air together, and the dam thing does not charge properly. My TB display charges my other 2 MBA (mag safe 1) and a macbook pro (magsafe 1) without any issues.

    Went to Apple, they replaced my magsafe charging unit inside the MBA, did not fix the issue.

    Apple needs to fix this, it's a major issue.

    Falls off!

    It does what it is supposed to do. But it doesn't keep being attached that easily as you might would have expect. If you lift your mac, turns it a little on the table, or anything else.. it just pops right off. It's not the magnet that there is anything wrong with.. it just isn't designed to be that handy. But it works though..

    No use with mavericks

    Since upgrading to Mavericks, I can no longer charge my laptop using an old PSU and the magsafe adapter. It will keep the device at constant battery, but not charge it if it's low. The adapter is therefore useless.

    On Mountain Lion, it worked fine for charging the laptop.

    Weak light

    Tried two of these converters on two different cinema displays, the green light is almost always very weak. Only sometimes after wiggling does it work. Sometimes the MacBook won't even wake. It's not the MacBook though, as it works perfectly on the normal power adapter. Not sure I want to buy a third one to try...
    Pros: looks good
    Cons: barely works.

    I’m Happy!

    It works! Well worth the price--made my 24” Cinema Display usable with my new 13” MacBook Pro w/Retina. Very happy!

    Converter works sporatically

    This converter only works some of the time. I usually have to jiggle it before the light goes on and the computer starts to charge. But I often forget to check so my laptop doesn't charge until I remember to jiggle it. I have 2 of them and both have this problem.

    On the positive side the magnet is pretty strong so it won't get knocked off too easily - only if the cord is pulled on.

    It's as good as MacSafe 2 itself

    Let's be honest here: the old L-shaped MagSafe 1 connector was far superior, it had a very strong and reliable connection. The new MagSafe 2 gets disconnected much easier.

    However, people who claim that this converter thing is loose simply don't factor in that the original power supply is exactly as loose. This converter is no worse than the new MagSafe 2 connector itself! So if you have a rMBP or MBA, then you have MagSafe 2, and nothing will change that. You either spend a lot of money buying a second power supply, or you spend $9.99 for this converter, and they're equally as good (or as bad).

    Using the converter is pretty much the same as using the new factory power supply. Yes, it gets disconnected too easily, like the factory power supply. We may complain about MagSafe 2 itself, but this adapter is as good as it gets. I'm using it with my TB display, and it does the same job as the laptop's power supply.

    If you want to give feedback to Apple, by all means complain about the new connector. But I'm giving feedback to other consumers here: this converter is a good purchase anyway, if it prevents you from buying a brand new full power supply.

    Not satisfied

    The idea of this i very good, and the converter is very robust despite its size.
    But there are a few problems. It charges rather slow and it gets pretty hot pretty fast.
    Sometimes it has got problems with charging, and the % keeps steady at whatever % i started charging from. This is getting worse with time, though i have only been using it for a year :-(

    Fixed charging problem by scraping off build-up

    I own three of these little devices, and they used to work fine, but two have lately been acting flaky. I'd plug my 15" rMBP into my old monitor at work and the light would not light up, or it would show green (fully charged) when the battery was not.

    The solution? I noticed some "grey buildup" on the laptop facing side of the connector. When I scraped it off with my fingernail, it started working more reliably.

    MBP Retina not charging

    I am using this adapter with a Thunderbolt Display. MBP charges randomly and keep on loosing contact.
    I hope we get a better solution soon.

    MacSafe 2 connector a step backwards

    Even without the adapter the MacSafe 2 connector gets easily detached and looses connection during work. The MacSafe 1 plug was smaller, could be used to charge the MacBook Air even within the cover. All impossible with the big MacSafe 2 plug. Due to the permanent detaching problem I returned to use my old MacBook Air. 12h of battery life is useless if you start work with an uncharged system.

    Please please provide a MacSafe 1 plug for the new MacBook Air!

    Works but Dies

    The Adapter that came with my Thunderbolt Display worked for about 4 months. Did what it was supposed to do, but then suddenly I noticed my MBP Retina wasn't charging anymore when connected to the Display. Luckily I had a spare adapter and it works again.

    Postitive - It does what it's supposed to.
    Negative - Dies after a while.

    Works Fine, But Easy To Lose

    This adapter does what it says so is useful to have, but it is so tiny that it is very easy to lose. I wish it had a hole through it so I could hang it from a keyring on my bag when it is not in use.

    Very positional, doesn't always work.

    I often find I need to wiggle this when in use to ensure the power is flowing through it and the lights come on to indicate charging. Very annoying to plug the computer in and have the charging lights come up, then discover later on that it hasn't charged much as all because I've moved the laptop some small degree and the charging adapter has stopped transferring the energy. Only rarely do I attach the MagSafe charger & converter to my Macbook Pro Retina and have the lights immediately come on, they almost always need a wiggle even when I've carefully aligned them on each other! :(
