Which cable for charging do I need for Mac 17 inches
Power cable for my old MacBook Pro 17 inches

Because Apple has ceased manufacturing of the 17-inch MacBooks, existing ones still use the MagSafe 1 interface. A MagSafe 2 power adapter will not work with any of the 17-inch MacBooks. In conclusion, you will need a MagSafe 1 power adapter with an 85-watt rating.

No, this is only for the newer MBP. The connector is different. You need to get the original MagSafe charger (Apple 85W MagSafe Power Adapter (for 15- and 17-inch MacBook Pro)).

No a 85W MagSafe 2 power adaptor is not compatible with a 15" Macbook Pro Late 2008, only a 85W MagSafe 1 Power adaptor. If you're looking for a 85W MagSafe power adaptor go to the apple store or apple.com. MagSafe 1 and 2 power adaptors are 2 different sizes.

It should work the same. The charger doesn't "force" current into the computer, the computer draws what it needs from the charger. The MBA will only draw 45W max so the 85w charger will easily provide the needed current. The problem happens when you try and use the 45w charger with the 85w computer. It will try to draw more current than the charger will deliver and that can cause problems.

Yes, but we (MBP retina owners) are willing for a DC adapter, or at least an open connector for DIY.

You will need to buy the World Travel pack which includes the adapters for different countries.

Hello Efrain, sure it does! Once your charger turns green it indicates it's fully charged and therefore stops charging the battery but uses the extra current for the computer itself.

Is it o.k. to swap a.c plugs (duckheads), from one adapter to another?
I have a 85w megasafe2 adapter and a magasafe 60w adapter, and I am not sure if the a.c. plug I am using is from my 60w, or my 85w adapter, and I am using the plug on my 85w adapter.

The fact is that the old 85W MagSafe adapter and the new 85W MagSafe 2 adapter differ in their electrical specifications, not just the connector:
Old 85W MagSafe adapter:
Input: 100-240V, 1.5A, 50-60 Hz.
Output: 16.5 - 18.5V, 4.6A
New 85W MagSafe 2 adapter:
Input:100-240V, 1.5A, 50-60 Hz.
Output: 20V, 4.25A
We all know now that there is an adapter available to make the connector of the old MagSafe adapter fit the new rMBP, but the real question is what effect the voltage difference will have. Will it work? WIll it charge more slowly? Does the rMBP have internal circuitry that fully compensates? It will take someone with real technical knowledge of the new rMBP to answer this one.

A bit late for this person, but for future reference: Always use the power supply WITHOUT a voltage converter. The Apple power supply reads the correct voltage and adapts to the country you are in. You just have to have the correct plug for the local elctric sockets.
The power supply is universal but the plug on your cord matches the sockets in the country where you purchased the computer. So a U.S. computer has a different plug than those for England, Germany, or Italy, etc.
1) The large, thick power cord for your computer is not permanently mounted in the power supply. Remove the cord by placing the power supply on a flat surface and pushing the cord firmly, sideways out of the body of the power supply. Do this squarely, noting how it attaches (genius really). In addition to the power cord, your computer came with a small white plug from the country where you bought the computer. It slides directly into the power supply in place of the power cord. This allows you to plug the power supply directly into your home country's electric socket without the long, thick cord.
This white plug can be replaced with different proprietary Apple plugs for different countries. If you plan on traveling to a lot of different places, buy the World travel Pack that contains multiple plugs.
Or, when you get to the country you are visiting, go to the Apple store there and buy either the correct plug for that country or a new power cord with the correct plug (or both). Install one in your power supply.
2) Buy a the correct plug adapter for your new country. Plug your home country's power cord or small white plug directly into this adapter. The local adapter plugs directly into the electric socket.
3) You can buy a new power supply in the country you are visiting. It will have the correct cord and plugs for that country. If your power supply goes bad abroad and you buy a new one, save your home country's cord and plug to use when you get home.
