Laptop charging with USB port

New standard USB Power Delivery helps common cables that can power laptops similar to other mobile devices.

The new standard enables USB cable to transmit 100W of power.

Current users can use the USB port to charge mobile phones, tablets, music players or some other devices. However, in the near future, this common cable will be used to charge laptops for batteries. USB Implementer forum this week has passed new standard USB Power Delivery that supports power transfer up to 100W via USB cable.

Laptop Magazine had the opportunity to "market" the laptop model with the new charging standard at USB-IF booth at CES last week. A special feature is that the device can both charge and exchange data simultaneously. If the user plugs a laptop into an extended screen, in addition to transmitting image signals, the cable also helps to charge the computer quite conveniently.

CEO, Jeff Ravencraft, of USB-IF said that the product tested was actually an old Dell laptop modified to connect a USB port that supports USB Power Delivery. The cable model is then connected to a Lenovo ThinkVision monitor to both send power and receive an image signal.
