Yes, the computer knows how much power to draw, and using an 85W adapter on your 13inch MBPro will be perfectly safe.

Yes it is, because the adapter was designed to work from 100 - 240 V.

Will it hurt my macbook pro if i leave the power supply plugged in to the wall socket and in to my 2011 Macbook Pro at all times (mostly)?
My Macbook Pro stays on my desk for the most part. Will it hurt to leave it plugged in all the time, or should the battery be cycled on a regular basis?

It's recommend for 2014 MacBook Pro to keep on charge whenever you can, there is no need for drain the battery 0% to charge full,
Charge your Apple lithium-ion battery whenever you want. There’s no need to let it discharge 100% before recharging. Apple lithium-ion batteries work in charge cycles. You complete one charge cycle when you’ve used (discharged) an amount that equals 100% of your battery’s capacity — but not necessarily all from one charge. For instance, you might use 75% of your battery’s capacity one day, then recharge it fully overnight. If you use 25% the next day, you will have discharged a total of 100%, and the two days will add up to one charge cycle. It could take several days to complete a cycle. The capacity of any type of battery will diminish after a certain amount of recharging. With lithium-ion batteries, the capacity diminishes slightly with each complete charge cycle. Apple lithium-ion batteries are designed to hold at least 80% of their original capacity for a high number of charge cycles, which varies depending on the product.

What do I need to use my Macbook Air laptop in Europe?
Low tech woman seeks simple answers and solutions for bringing my Mac Air laptop on a plane to Germany and being able to travel to nearby countries and have the power cord and voltage be compatible. I saw something online for an airplane power mag cord which can be used. I saw the World Travel Kit for Apple online, but I'm not sure if this is overkill. What's the minimum requirements I will need?

The Apple power supplies are dual voltage (and dual frequency), so all you need is a European plug adaptor.

So 85 watt charger will not harm the Mac Book Air? I would not want to have to toss them out now that I have moved from Pro to Air models.

Yes you can. It works, fine for mine. Since I have both Mac books. I am only using the 85w. You can use a higher watt to charge a lower watt item. Just you cannot use a lower watt for a higher item. Go read a few and they all agreed.

How do I use the Magsafe power adapter?
It's in two pieces. Do they connect? Do I use both at the same time? I plugged the white box into the wall and the other end into the computer and it appears to be recharging. What do I do with the other piece that has a wall receptacle prong, but I don't know what to do with the other end!

The prongs piece comes apart from the white box by sliding it out. You may then slide the long corded piece in for extra length!

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
macbook europe power adapter
I'm going to spain with my macbook pro. Do I need a power adapter to step down from 220 to 110, or does the regular charger on my power cord handle that for me?

The white box is a built in power converter so you should be fine with plugging it in as long as you have the adapter that changes plug types. You can check to see if other things are converters if it has something like Input: 100-240V~1.5A 50-60Hz. This shows that an electric current of 100-240 Volts can power the converter without problem, which Spain's electricity falls in. If you cannot find this on a product (though most electronics made in about the last 5-10 years automatically convert) or if you feel you would rather side with caution you can but a converter, but only leave it plugged it when you need the power because converters burn out quickly from overheating if you leave them plugged in too long.

- Flag as inappropriate (do i need a converter for the Apple TV to go from 110v to 220v?)
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.

Can I use an 85W magsafe power adapter to safely charge my MacBook Air?
- Asked by Bryce B from New York

- Flag as inappropriate (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, 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.

iPhone chargers work from 110-240V. No issues on the voltage for the iPhone USB power adapter. It is designed to work worldwide thus the 100-240V.
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.

- Flag as inappropriate (What power cable will I need if I move to Australia?)
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.
