USB-PD to Revolutionalize Laptop and Ultrabook Charging, end Power Brick Chaos


Everybody at some stage in their life has had to lug around a laptop power brick. You know what we are talking about; that bulky and ugly plastic thing attached to a cable which never quite stretches far enough to where you need it to go. Well now there may be a direct replacement for it, and the future doesn’t look so far away.

The future comes from USB 3.0 Promoter Group, who have announced a brand new 100-watt power delivery standard called USB Power Delivery, which being referred to as USB-PD. USB-PD boosts the maximum current to 5 amperes and maximum voltage up to 20 volts from older USB technology. This, in consumer terms, means that you may no longer have to charge your laptop or Ultrabook through a dedicated charging port nor be tied to a rather inconvenient power prick. With USB-PD technology, you’ll be able to charge high powered devices directly through USB.

Here are the features of USB-PD, as built upon by

  • An increase in power levels from existing USB standards up to 100W.
  • Device power direction is no longer fixed. This enables the product with the power (Host or Peripheral) to provide the power.
  • Optimize power management across multiple peripherals by allowing each device to take only the power it requires, and to get more power when required for a given application.
  • Intelligent and flexible system level management of power via optional hub communication with the PC.
  • Allows low power cases such as headsets to negotiate for only the power they require.

Current estimates for this technology state that USB-PD could be integrated in to next-generation machines as soon as 2013.

As Information Week has noted, this is a pretty significant improvement over the existing 2.5-watt capability as seen in many devices and even 10.5-watt devices on the market such as Apple’s iPad tablet computer. With USB-PD technology, and the new MHL USB standard, USB is all set to become a universal three-in-one connector for tablets and notebooks and revolutionize charging.

To find out more about this rather exciting development within the technology industry, as well as hit up an interesting chart comparing the original USB specification against the newer one, follow our original source for this story below.

    I have realized some new elements from your internet site about computers. Another thing I have always thought is that laptop computers have become a specific thing that each house must have for many reasons. They supply you with convenient ways in which to organize households, pay bills, shop, study, tune in to music and in some cases watch tv series. An innovative technique to complete many of these tasks has been a mobile computer. These computers are mobile ones, small, effective and portable.
