Apple 45W MagSafe Power Adapter for MacBook Air
Apple 45W MagSafe Power Adapter for MacBook Air
The 45-Watt MagSafe Power Adapter for MacBook Air features a magnetic DC connector that ensures your power cable will disconnect if it experiences undue strain, and helps prevent fraying or weakening of the cables over time. In addition, the magnetic DC helps guide the plug into the system for a quick and secure connection.
When the connection is secure, an LED located at the head of the DC connector will light up; an amber light lets you know that your portable is charging, while a green light tells you that you have a full charge. An AC lead is provided with the adapter for maximum lead length, while the AC wall adapter (also provided) gives users an even easier and more compact way to travel.
Redesigned specifically for MacBook Air, the adapter is the perfect travelling companion. It has a clever design that allows the DC cable to be wound neatly around itself for easy cable storage.
This power adapter recharges the lithium polymer battery while the system is off, on, or in sleep mode. It also powers the system if you choose to operate without a battery.
Compatible only with MacBook Air with MagSafe Power Port.

It's recommend for 2014 MacBook Pro to keep on charge whenever you can, there is no need for drain It's recommend for 2014 MacBook Pro to keep on charge whenever you can, there is no need for drain the battery 0% to charge full, Charge your Apple lithium-ion battery whenever you want. There’s no need to let it discharge 100% before recharging. Apple lithium-ion batteries work in charge cycles. You complete one charge cycle when you’ve used (discharged) an amount that equals 100% of your battery’s capacity — but not necessarily all from one charge. For instance, you might use 75% of your battery’s capacity one day, then recharge it fully overnight. If you use 25% the next day, you will have discharged a total of 100%, and the two days will add up to one charge cycle. It could take several days to complete a cycle. The capacity of any type of battery will diminish after a certain amount of recharging. With lithium-ion batteries, the capacity diminishes slightly with each complete charge cycle. Apple lithium-ion batteries are designed to hold at least 80% of their original capacity for a high number of charge cycles, which varies depending on the product.

There are multiple options available to you: If you are in North America with the 2 Flat-Pin connect There are multiple options available to you: If you are in North America with the 2 Flat-Pin connector, you can plug this directly into a typical pin converter (will adapt the 2 Flat-Pins to 2 standard Euro-Pins). This is because the 29W USB-C Power Adapter supports multiple input voltages (100-240V). This option is risky, and you will find that this pin-converter will get quite hot. Manufacture is not quite up to "Apple Standards". The best option is to purchase the World Traveller Kit. This has multiple adapters for more than 90% of countries in the world. All are approved for use on all Apple power adapters.
