can I use a 85W on my macbook 13"?
My 60W charger died, but I was given a 85w charger. Can I use this, or should I buy the 60w?

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

Does anyone know if all of the three available Magsafe adapters - 85W, 60W and 45W - are the same physical size?
Adapter dimensions

Answer
All three are different sizes, and obviously the higher the wattage, the larger the adapter. I frequently swap between all three (I own 3 laptops - 11", 13" 15"). Using a 45W on the 15" results in a slower charge, but it still charges. With the higher wattage chargers, they can be used on a lower need laptop with no issue at all. The laptop just draws what it needs.

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?

Best Answer
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.

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.

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

Best Answer
This KB article states that you can use higher levels with a lower requirement. Note you cannot use lower with a higer.
So a 85W charger (MBP 15/17) will charge a 45W device (Mac Air)
But a 45W charge (MBA) will not charge a 60W or 85W device

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?

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

can I use the non-grounded portion of my 60W magsafe charger in Europe without running the risk of damaging my macbook pro 13"?
I am traveling to Europe from the US and I plan on bringing my MacBook Pro 13". I only want to bring the smaller portion of my 60W magsafe charger to take up less room. Will I run the risk of damaging my computer if I don't bring the Ground plug portion of my charger? Or will it not matter? FYI the ground plug portion is the three prong part compared to the non-grounded two prong part.

Is it ok if i use the 85w for my 13
- Asked by Jordan H from Laurel

Answer
Yes. The laptop only draws as much power as it needs. So a higher wattage cord is compatible as long as it fits, as this one does, unless you have a new retina.

do i need a converter for the Apple TV to go from 110v to 220v?
- Asked by Paul B from Salt Lake City
- Nov 19, 2009

Best Answer
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.

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?

STANDARD MAINTENANCE:
For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Apple does not recommend leaving your portable plugged in all the time. An ideal use would be a commuter who uses her notebook on the train, then plugs it in at the office to charge. This keeps the battery juices flowing. If on the other hand, you use a desktop computer at work, and save a notebook for infrequent travel, Apple recommends charging and discharging its battery at least once per month.
LONG-TERM STORAGE:
If you don’t plan on using your notebook for more than six months, Apple recommends that you store the battery with a 50% charge. If you store a battery when it’s fully discharged, it could fall into a deep discharge state, which renders it incapable of holding any charge. Conversely, if you store it fully charged for an extended period of time, the battery may experience some loss of battery capacity, meaning it will have a shorter life. Be sure to store your notebook and battery at the proper temperature.- Answered by Gary S from Jacksonville Beach
