Notebook, as a tool of mobile productivity, allows people to experience the convenience of handling work in different places. When it comes to Notebook Charger, I believe that many people's first impression is the big black brick, which is not only huge, but also heavy.
So the notebook manufacturers start from their own source, make a comprehensive transition to usb-c multi-functional interface, and redesign the compact charger. Today, let's take a look at the usb-c chargers for the laptops launched by Xiaomi.
Q: the power of notebook PD charger is so high, can it charge mobile phone?
A: the notebook PD charger is compatible with USB PD fast charging standard, which can not only charge the notebook, but also be used in other digital products. All of Xiaomi's notebook PD chargers contain a wealth of output voltage files. Mobile phones usually use 9V voltage, and tablet commonly uses 15V voltage. As long as the corresponding model has these voltage outputs, it can provide PD fast charging for mobile phone tablet.
Q: what's the difference between Xiaomi's PD charger with usb-c cable and that with conventional usb-c interface?
A: Xiaomi has launched two PD chargers with usb-c cable. In fact, both PD chargers with conventional usb-c interface can be used as PD chargers. The built-in cable is usb-c output port, which also supports PD fast charging, and the built-in cable has more protection at the outlet position, and the anti bending design is more durable. The conventional usb-c charger without cable allows users to replace different cables, taking into account the usb-c device and lightning device.
