I bought my Mac Book Pro about a year ago. After a short while, I discovered that its battery isn't the best, and unlike Apple's claims (more than 7 hours of intensive usage), I could only squeeze about 1-3 hours of battery life, depending on what I was doing with my laptop. I decided to buy another charger to keep in the office, I bought this one, and surprisingly, it was awful. When connecting it to the machine - only one time out of two it was charging. In other times the onscreen message was "connected but not charging". After going back and forth with the Apple support team, we discovered that the Mac Book Air charger has lower voltage (45Watt) than the one needed for Mac Book Pro. The apple support team mentioned that it is good enough to keep the MBP alive (i.e. to maintain operation), but not to charge the battery. So, my recommendation is the following - if you have an old Mac Book Air charger, use it to work with your Mac Book Pro. It won't violate the warranty, or hurt your laptop. It won't charge your MBP though so if you do own a pro, pay close attention to the charger that you are buying... Overall, it was my bad for not reading the fine print, but it should be a warning for all of you, as this can be confusing!
I've had a MacBook Air since Christmas (which I love by the way!) and I was given the Magsafe Power Adapter with it when I purchase it. I have looked at how much these cost to buy by itself, and I was actually shocked to discover that it will set you back between £40 to £60 - which seems ridiculously expensive for a power adapter, even by Apple's standards! The power adapted comes in two parts - which easily slot together. The unique feature about this power adapter is that it connects to the computer by magnet and therefore there is no chance of the adapter damaging the computer or damaging itself if there is stress on it. I have had a number of laptops in the past where the adapter prong has become bent or otherwise damaged in some way, and this has meant I've had to repair the computer as it was impossible for it to power up - which is really annoying! Thie magnetic connection method means that the adapter simply becomes un-stuck and there is no damage to the laptop or the connector. The magnet is strong enough that it does not continually become accidentally detached from the laptop - but on occasion this will happen. I like the fact that when storing the cord for travelling, the cord can be wrapped around the adapter itself securely so that the leads do not become tangled - and also so that it takes up less room. I also like the fact that there are two options for plugging the adapter into the wall - either via the main block or with the extension attached. I usually use the extension as I like the length it gives me and the freedom to move around. The only negative is that the power block does tend to get pretty hot with it's being used - although it cools down quickly afterwards. Overall, while expensive, I think this is a great adapter and far superior to the other adapters that use the typical prong design. I do wish the price would come down though!.
When I first got my used macbook it had no power adapter and naturally I was not pleased that apple wanted so much money to get me up and running. Of course I had to shell out and now i have its clear why apple can ask high prices. Their products are just so well made. It's not just the reputation that makes you think apples gear is better than others. The unit is beautifully designed and made and extremely hard wearing. Little touches such as the angled cable holders that fold out from the corners show you how much thought has gone into it, the wire itself is thin enough to flex but still strong enough to wind up repeatedly. The main unit can plug directly to a wall socket or into an extension, each of which plug seamlessly into the main unit. Of course the true breakthrough is the magsafe connector, plug this into your mac and you no longer have to worry about kicking you precious machine to the floor. The connector plugs into the mac with a satisfying pull but will always pull free before moving your mac. It really is genius
The MagSafe Power Adapter for MacBook Air features a magnetic DC connector that ensures your power cable will disconnect if it experiences undue strain and 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.
An AC cord is provided with the adapter for maximum cord length, while the AC wall adapter gives users an even easier and more compact way to travel.
Redesigned specifically for MacBook Air, the adapter is the perfect traveling companion. It has a clever design which 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.
