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 USB.org:
- 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.
