Questions & Answers for Apple 60W MagSafe 2 Power Adapter (MacBook Pro with 13-inch Retina display)

No. MacBooks and other laptops can't be charged by USB because USB ports can't handle the amount of wattage it takes to charge a battery of that size. The iPhone, for example, only requires a minimum of 5W to charge, while MacBook chargers start at 60W.

Yes it is. Power adapters for Intel-based Apple notebooks are available in 45W, 60W, and 85W varieties. Although you should always use the proper wattage adapter for your Apple notebook, you can use an adapter of a higher wattage without issue.

Yes. Apple says it is perfectly safe, however your MacBook Air will not charge any faster using a 60w charger than using the included 45w charger. But it is safe.

Yes, as far as I've checked and tested: using the old extension cord from a busted magsafe on the new retina pro magsafe in office and the new one at home, so I don't drag the extension cord with me everytime along with the magsafe adapter brick. It's just a basic electric cord that works with all Apple power adapter bricks, even the iPad ones. You can even check it has the same specs written on the cable.

To be perfectly clear, we are talking about just the extension electrical cord from the outlet to the magsafe brick, and not the magsafe adapter itself.

No, you require one of the "T" shaped MagSafe 1 60w charging adaptors.

The guy at the Apple Store on 5th Ave said they use the 60 Watt charger on all the computers in the store. Doesn't matter if you use the higher 60 watt on a smaller computer that came with a 45w.
