At CES 2013 showed a laptop powered by a 100-watt USB 3.0 data cable



    Rumors about the new standard, USB Power Delivery, which allows charging not only smartphones and tablets via USB cable, but also, for example, laptops (while data is being transferred in both directions), appeared back in 2011. Last year, in the summer, the standard was adopted through the efforts of the USB 3.0 Promoter Group. Well, already this year, 2013, the first laptop was shown, which is really compatible with the new standard.

    At the same time, the laptop itself is not at all special, super-modern. The developers took the old Dell laptop model, and modified it, making it compatible with the new standard. In this case, the laptop was powered by a USB cable connected to the monitor. Thus, the monitor gave the laptop energy, and the laptop sent data to the monitor (HD video and pictures).

    Here are some videos:



    It is worth noting that the USB Power Delivery standard does not replace, but complements USB 2.0 and 3.0, plus it is backward compatible with the specified specifications. In appearance, a cable that supports USB Power Delivery is indistinguishable from a conventional USB data cable. Of course, the developers who introduced the new technology at CES did not use a laptop charger at all, providing it with the USB Power Delivery standard.



    A big, but not very obvious advantage of this technology is that laptops with USB Power Delivery support will not need different power supply connectors. You yourself know how many types of connectors exist, almost every manufacturer has its own connector.

    In Europe, a law has long been passed that obliges manufacturers to create new models of phones with a microUSB connector so that you can use any charger with this connector for any phone. It may well be that after a while the corresponding rules for laptops will be adopted. It would be nice if the new laptop models support USB Power Delivery. Then, problems with broken plugs and broken cables of laptop chargers could be forgotten.
