Questions & Answers for Apple 45W MagSafe Power Adapter for MacBook Air
475 Questions from the Community
Does it harm my macbook pro retina 13'' (2015) battery to keep it connected to the wall socket even after it is fully charged?
Should I disconnect the charger after the battery percentage reaches 100% or is it ok to use it after it reached 100%? Also, what is the minimum battery percentage before I start charging again? Is it bad to completely drain the battery sometimes (twice in a month)? I am sorry for the question for being so long, but I really want to optimise my mac battery. Thanks for the help in advance.Best Answer:
I'm surprised that no one ever answered your question, and i only started coming to Apple Community recently, sorry for the late notice and late reply, and hope this is still helpful to you :)
Here are the answers to your questions:
- Try not to deplete the battery as this actually harms the battery lifespan.
- charge your MacBook Pro when it has about 5-10% battery remaining, MacBook and MacBook Pro has a power management system integrated since Mac OS 10.11 El Captain, if your battery is below 10%, Mac will automatically reduce hardware performance to preserve remaining battery charge and you will start experience lag, functioning delay, longer loading / processing time. it doesn't hurt the battery itself, but the lag could drive you mad.
- Keep your Mac on the charge all the time while you use it would damage the battery? Theoretically NO.
The general technology has developed so much so as the battery technology.
Theoretically what Today's laptop would and should do is to deactivate the charging when it calibrated the charge in the battery. which means there is no more electric charge goes into the battery anymore.
From personal experience, i'm doing that all the time, i only take it off the charger when i actually take my MacBook outdoor. And my battery does exactly the same performance and duration as the first day i got it (owned my MacBook Pro for 1 and half year now)
And i never power off my MacBook Pro since Apple has done so well with Mac's power management system (way better than Windows and by miles)
But, if you aren't using the MacBook, and put it into sleep mode or shut down. then disconnect the charger. What i said above only applies to MacBook being 100% charged when you are using your MacBook or it's powered on all the time.
To be honest, the excuse of Overcharge laptop by leaving the charger connected is simply not acceptable. because this is a basic precaution that portable electronic manufacturers should have been dealt with long time ago

It basically comes with a power adapter for a MacBook and Macbook Pro NOT MacBook Air and it also comes with an extension cable for the power adapter. Because the power adapter cable is quite short, however with the extension its a perfect length.

I am going to the Philippines and I'm using this charger for my Macbook Pro. Can I just plug it in there directly? They use 220V and 60Hz there.

Yes. All of Apple's new power adapters are designed to be World Travel friendly. Just like many other power adapters for cellular phones, etc.
Apple's power adapters will support voltages from 100-240V and 50-60Hz.
The only additional thing you will need is the International Adapter kit, so you can plug in your power supply to the given wall plug.
Can I use an 85W magsafe power adapter to safely charge my MacBook Air?

If the ports of the adapter fit your macbook air, it means it is designed to be compatible with the air.
So answer is yes if the port fits. 85W just means that it has larger capability of supplying larger current with the same voltage when it is necessary. So when you plug 85 W power adapter into your air, it will give just enough current to the Macbook Air. Since the voltage is kept the same, it won't cause any problem.

Yes, you can. I bought my MacBook Pro in Canada, and travel to South Africa every year, where power is 220V at 50 Hz. The Apple power supply works fine there.
You can in fact use all modern Apple power supplies (for iPhone and iPad) anywhere in the world where power is 100 to 240 V, 50 or 60 Hz.

I'm taking my 13inc MacBook to Australia. Do I need a voltage converter?

You shouldn't need a voltage converter. Australia is 220 volts, 50 Hertz. Check your adapter. It should say "110-240 volts, 50-60 Hertz" You may need an adapter to match the outlets there. You can search for "electrical outlet Australia" to see what the proper shape is for the country. You can buy a set of adapters that will cover most countries in many consumer electronics stores, or large discount stores. Then you will be set wherever you travel.
Have a good trip.

No. Apple power supplies are rates 100VAC to 240VAC. You want to look for the proper power cord to prevent having to use a bulky plug adapter. I suggest calling Apple at the 1-800-My-Apple to order a power cord for the country you plan on using the device in. Something to consider is other countries that use 220VAC also use PAL instead of the US's NTSC.

100-240V AC. It is safe to use worldwide, you'll just need an adapter to make it fit in the wall outlet.

Yes, it will work, but you need an adapter plug ($9.99 at Radio Shack, Model: PCC-1 | Catalog #: 273-1448). New Zealand electrical grid is 240 V, 50 Hz. Written on the side of the Power Adapter is: "Input 100 - 240 V" and "50 - 60 Hz". That covers it.
Have a nice trip.

Electrically: Apple's MagSafe adapters are labelled for AC input of "100-240V 50/60 Hz". They should work worldwide. (Mine does).
Physically: Most of Italy uses European-style two-round-pin AC sockets. There are local variations - some sockets have earth/ground connectors also, though the Magsafe adapter does not need this. You can get many converters to convert from US flat-blade mains plugs to Euro-style sockets. Best is to use the correct Euro-plug to fit directly on the MagSafe in place of (say) the US flat-blade AC plug. Second-best is to use a lead from Magsafe's own Figure-8 AC connector to the wall socket. This prevents the weight of the Magsafe dragging itself out of the wall outlet.
Air Transport: You should carry your adapters with you so that you can power-up your laptop for security at any airport you pass through.

Yes, it will. I did the reverse couple of years ago. Moved from South Korea to UK with MACBOOK 13" on 60W Mega Safe (16.5V/3,65A) adaptor which works just fine till now.
Does the 45W work with the 2011 MacBook Air?
I need a new power adapter for my 2011 MacBook Air because my original power adapter split open and the wires on the inside are now exposed. The charger, where it has split gets extremely hot, to the point where it burns me. So I just wanted to know whether the 45W fitted the 2011 MacBook Air. Thanks :)
