Big secret of the 12-inch Retina MacBook: Charging with mobile power

Apple's new 12-inch Retina MacBook has only one USB-C interface, but this interface is powerful. It not only can transmit data and video output, but also can receive and input power. This means that you can use the mobile power to charge it if you have a USB-C to usb-a cable.

Unlike the previous magsafe,usb-c, which is a common technology, it also makes the new MacBook the first model in the series to be recharged with a mobile power supply. While the previous MacBook model can be recharged with a dedicated mobile power supply such as hyperjuice, you'll need to buy a custom MagSafe adapter or tweak your MacBook adapter, which is obviously a hassle.

Apple claims that the new MacBook offers a 10-hour battery life for a single charge, while the actual endurance of the device is about 7 hours, according to media testing. If a large-capacity mobile power supply is used, its endurance will be further extended.

While the MacBook's USB-C interface makes many people feel inadequate, its ability to do so is still impressive. MagSafe may be remembered, but the new USB-C will make you no longer bound by wall sockets.
