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, 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.

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.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
What power cable will I need if I move to Australia?
I might be moving to Australia next year, and I'm wondering what i will need to charge my Macbook over there. I am currently living in Canada, and I own a 15" (White) Macbook.

The power adapter that came with your MacBook should be suitable for 100 - 240v AC 50/60 Hz. All that you will need to change is the actual head that sits on the power adapter. In Australia (240v 50Hz), we use two angled pins with a third earth pin (the earth is not required for double insulated appliances like your MacBook power adapter).
The head for the power adapter for Australia is 603-7715 or for a complete 1.8m power lead with head is 590-5259.

What numbers are used for identifying my power adapters?

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 this will work. I called Apple and verified it. I then purchased the Magsafe 85W power adapter and it works well. However , Do NOT buy the Magesafe2 power adapter for the Macbook Pro 17" A1229 though. It has the wrong interface.
Hope it helps.

What is the length of this cable?
I always study in my college library, but the plug is far from my desk. My original charger is too short, so I need a long one that can reach my desk which is usually far away from the plug of our library. I wonder if anyone can tell me how long its cable is. Thank you!

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.
Yes, If your computer is 2006 or later it should work.

My A1222 charger has just died, does this product replace it or do I need to replace it with what I had originally? I have a May 2008 17" MP

- Flag as inappropriate (My A1222 charger has just died, does this product replace it or do I need to replace it with what I had originally? I have a May 2008 17" MP)
Yes. I have same laptop as you, and I have a new one, the new charger, charges both.
The old charger, the one that died on you only charges the older laptop. You can find the old ones online but every add is sketchy, it's either not an original apple model and they trick you or sneak in the "compatible" word, or it's a refurbished and it's missing either the short plug, or the extender cord, you should get both otherwise it's not worth it.
This current model works, I've charged my old system with it many times, but I still have the old one working too.
Like many others mention the key is that you need 85W and both the old and this new one are 85W.

Yes, my charger (a 60W) has an input range of: 100-240V and 50-60Hz. I see no reason why Apple would not make their 85W charger the exact same.

Your older MBP required an 85W power adapter. The newer model requires a 60w power adapter. If you are buying another adapter to wokr with both products, buy an 85w power adapter.

Doubt there's a charging device available as the output on the Macbook Pro Charger is 16.5V DC, so a 12V power source wouldn't be sufficient for the Macbook. Hope that helps.
