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.

It's an extension cord. You pull our the prongs on the white box, slip in the base from the cord, then plug in the cord. It gives you more cable.

MagSafe 2 is Apple's update to their power supplies. It's more energy-efficient, charges faster, doesn't heat up as much, and is more difficult to break.

The MagSafe 2 magnetic connection is more shallow than the MagSafe was, which could reduce the risk of poor connection caused by a bend on the connector.

You could use an adapter to convert a MagSafe to a MagSafe 2 connection, but I don't think it will cause it to charge more efficiently. Be careful to always use the correct wattage on your computer, too. Just because the connection fits doesn't mean it should be used to charge your laptop.

No they will not send you a new one, you are responsible if the power adaptor gets lost. Warranty only covers if your MacBook or power adaptor is defective or something happens to it on its own within that warranty period. What your saying is like "My MacBook is under warranty, if i loose it will Apple send me a new one?"No.

1: Keep your batteries at room temperature


2: Think about getting a high-capacity lithium-ion battery, rather than carrying a spare


3: Allow partial discharges and avoid full ones (usually)

Unlike NiCad batteries, lithium-ion batteries do not have a charge memory. That means deep-discharge cycles are not required. In fact, it's better for the battery to use partial-discharge cycles.


4: Avoid completely discharging lithium-ion batteries



Also, for safety reasons, do not recharge deeply discharged lithium-ion batteries if they have been stored in that condition for several months.
5: For extended storage, discharge a lithium-ion battery to about 40 percent and store it in a cool place
