Does the power adapter continue to consume the same amount of energy when it is not plugged into the laptop (but still plugged into the socket)?
...or is there an energy-saving feature built in that reduces or eliminates its power usage when it's not actually charging a laptop?Best Answer:
I tested it with my killowatt meter and read 0watts when macbook fully charged or unplugged.
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.

From Macworld Mag 2006:
If you hold the two power supplies side by side, you’ll notice that the MacBook Pro’s is larger. That’s because the MacBook Pro uses an 85-watt power supply, while the MacBook uses a 60-watt power supply. Apple says you can use the more powerful, 85-watt power supply with a MacBook without any problems, and that in 80 percent to 90 percent of situations, you can use the MacBook’s power supply with the more-demanding MacBook Pro as well. If you’re really taxing the MacBook Pro’s processor with some heavy-duty work, the MacBook’s adapter will still be able to power the MacBook Pro—but it may not have any power left over to charge its battery.
so, yes, contrary to what everyone else has said, you can.

You could but it will charge very slowly and in some cases will just deliver enough power to run the macbook without any charge.
Get an 85.

Is the 60W MagSafe Power Adapter dual voltage?
I'm taking my 13inc MacBook to Australia. Do I need a voltage converter?
- Asked by Kimberly P from New York

- Flag as inappropriate (Is the 60W MagSafe Power Adapter dual voltage?)
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.

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.

Not at all. You might need a plug that will fit in their sockets though!

Can i use this A1344 60W Magsafe Power Adapter for MacBook Pro (15-inch, 2.53GHz, Mid 2009)
I recently purchased a 60W Magsafe Power Adapter, Model A1344 and a new battery Model A1281. Can both of these be used on my Macbook Pro 15"(MacBook Pro (15-inch, 2.53GHz, Mid 2009))
Model Name: MacBook Pro
Model Identifier: MacBookPro5,4
Processor Name: Intel Core 2 Duo
Processor Speed: 2.53 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 3 MB
Memory: 4 GB
Bus Speed: 1.07 GHz
Boot ROM Version: MBP53.00AC.B03
SMC Version (system): 1.49f2Best Answer:
2009 model originally used power adapter with model number A1184(60W), so electrically, this new A1344 should work. Here is the catch, if you update your mac in the following year, current 15 inch model requires charger with 85W power, so you will end up with a unusable A1344. On the other hand, 85W charger can be safely used with both old and new 15 inch model(old one will only drain 60W from it) So it will be a good back up even if you update the machine. The only down side is its slightly heavier weight and larger size.

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.

Any of the Macbook adapters, including the MacBook Air will run on any other Macbook model if you're only charging it when off or in sleep mode. The adapters are rated to handle the unit running the drive, display and processors under load. In a pinch you can use the 45 watt 'Air model to run the 85W 'Pro BUT I wouldn't recommend you run it that way except to quickly check your email, etc. If you HAVE to use the 45W or 60W to charge the battery in an 85W model, shut the laptop down, plug it in to charge and THEN run the laptop in the battery without the charger connected I have all of these models and have had to do this on occasion.

If your MacBook is a 2006 to present date, you don't need a power transformer/converter. Your present Power Adapter will accept Line voltage: 100V to 240V AC and Frequency: 50Hz to 60Hz. What you will need are Plug Adapters. Go to Apple Store type in power adapters in the search box and get the Apple World Travel Adapter Kit. It includes 6 adapter plugs.

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.
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 :)

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.

Just get a universal adapter plug for travel. They will usually handle all of the major interfaces in one unit. The adapter can handle any source voltage internationally from 100-240v, 50/60Hz.
