Genuine Original Apple MacBook Air Power Cord 45W: What You Need to Know

When it comes to charging your MacBook Air, using an original power cord is essential for optimal performance and safety. But what happens if you use a different power supply? Can you still charge your device effectively?

If you swap out the original 85W adapter with a 45W one, rest assured that your MacBook Air will still only draw what it needs. In most cases, this will be significantly less than the rated capacity of the charger. The power supply will never automatically run at 100% of its capability; instead, it will only provide the necessary power.

Using a lower-rated power supply like the 45W adapter is generally fine for everyday use. However, there are some potential risks to consider. For instance, if you need to charge your device quickly or perform resource-intensive tasks, using a lower-wattage charger might not be enough to meet its demands.

On the other hand, using a higher-rated power supply than the original unit can also have its downsides. While it may provide more power to your device, it's essential to ensure that the new adapter is compatible with your MacBook Air and meets the necessary safety standards.

In conclusion, when it comes to charging your MacBook Air, it's crucial to use a genuine original Apple power cord or one that meets similar specifications to ensure optimal performance and safety. Remember to always check the compatibility of any new charger before using it with your device.
