At CES 2013, a laptop powered by a 100-watt USB 3.0 data cable was shown

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

In this case, the laptop itself is not at all some special, super-modern. The developers took the old Dell laptop model, and modified it, making it compatible with the new standard. At the same time, the laptop was powered by 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).

It is worth noting that the USB Power Delivery standard does not replace, but complements USB 2.0 and 3.0, plus is backward compatible with the specified specifications. In appearance, a cable that supports USB Power Delivery is indistinguishable from a regular 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 know how many types of connectors exist, almost every manufacturer has its own connector.

In Europe, a law has been passed for quite some time, obliging manufacturers to create new models of phones with a microUSB connector, so that you can use any chargers with this connector for any phones. It may well be that after some time, appropriate rules will be adopted for laptops. It would be nice if the new notebook models supported USB Power Delivery. Then the problems with broken plugs and broken cables chargers for laptops could be forgotten.
