MacBooks are powered by direct current (DC) rather than alternating current (AC). This means that they require a power source that provides DC power. In the past, MacBooks used MagSafe connectors, which transformed the AC power from the wall outlet into the required DC power for the laptop. However, with the introduction of USB-C on newer MacBook models, the power input has shifted to DC.
USB-C is a versatile and powerful port that can handle various functions, including power delivery. It supports power input up to 100 watts, which is more than sufficient to charge and power a MacBook Pro. This means that the USB-C port on the MacBook Pro can receive DC power directly from a compatible power adapter or power bank.
One of the advantages of using USB-C for power input is its universality. USB-C is becoming increasingly common across various devices, including laptops, smartphones, tablets, and peripherals. This means that you can use the same USB-C charger or power bank for multiple devices, reducing the need to carry multiple chargers when traveling.
Another benefit of USB-C power delivery is its faster charging capability. With the higher power input of up to 100 watts, USB-C can charge a MacBook Pro more quickly compared to older charging methods. This is especially useful when you’re in a rush or need to top up your laptop’s battery during a short break.
Personally, I have found the shift to USB-C power input on MacBooks to be quite convenient. I no longer need to carry around a separate MagSafe charger for my MacBook Pro. Instead, I can use a USB-C charger that also works with my other USB-C devices. It has made my travel bag lighter and more organized.
It’s worth noting that while USB-C can deliver DC power to MacBooks, it’s essential to use a compatible charger with the correct wattage for optimal performance. Using a charger with a lower wattage may result in slower charging times or inability to charge the MacBook Pro while using power-intensive applications.
MacBooks, particularly the MacBook Pro models, are powered by DC rather than AC. The introduction of USB-C on newer MacBook Pro models allows for direct DC power input of up to 100 watts. USB-C power delivery offers universality, faster charging, and convenience for MacBook Pro users.
