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.

You can use it but I do not recommend it because it really takes a long time for a full recharge.

Does the 85W MagSafe2 Power adapter work on my macbook pro with 13 inch retina display without any damage?
I have already bought the 85W MagSafe 2 Power Adapter but lately be told the suitable power adapter should be 60W. If I still use the 85W, will the power adapter do some damage to my laptop?

- Flag as inappropriate (Does the 85W MagSafe2 Power adapter work on my macbook pro with 13 inch retina display without any damage?)
Yes. The 85W rating is the maximum amount of power this adaptor is designed to provide. by choosing this adaptor you can power any device that Apple currently sells which uses the magsafe 2 connector.
If you have a device that draws less power such as a macbook air that only draws 45W or macbook pro 13 that uses 60W then the adaptor just doesn't have to provide as much power. No downside. If anything, an 85W adaptor powering a lower power mac might even run cooler than the smaller 60W adaptor.

Are there any benefits to using the 85w Magsafe Pro2 Power adapter on 13" MacBook Pro Retina display?

"You can use a compatible higher wattage adapter without issue, but it won't make your computer charge faster or operate differently." This was taken from an article by Apple about charger compatibility.

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)).

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.

Size and compatibility.The 85w is larger/heavier than the 45w. The 85w will adapt to be used with a lower power computer (ie. the MacBook Air), but it was intended for use with the MacBook Pro with Retina Display.

- Flag as inappropriate Answer (What is the difference between the two power adapters?)
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.

By site they look very similar but the lower watt chargers are a little smaller and lighter. The best way to be sure is to look at the underside of the charger. The watts are written there.

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.

No it cannot because the older MacBook Pro uses MagSafe not MagSafe 2. The product you want is the Apple (60W for 13 inch computers or 85W for 15 and 17 inch computers) MagSafe Power Adapter.
