This new more powerful USB standard could mean death for proprietary laptop chargers. The small rectangular USB connector has been welcomed as an industry standard for connecting all sorts of accessories for every machine possible in the last ten years.
There isn’t much that that little thing cannot do, except one thing: to deliver plenty of charge in a short period of time. It is the organizations that manage the USB standard that have now done something about this issue. Now, this little thing is going to deliver power up to a total of 100 watts.
Upgraded after four years
“The USB Power Delivery Specification” is the official name of the standard is now approved by the “USB 3.0 Promoter Group” and “USB 2.0 Promoter Group” – two organizations that manage USB specifications. The new electrical specification is an extension of the USB 3.0 standard from 2008.
On the list of companies that are working to implement the standard, we find Intel, Microsoft, Texas Instruments and HP. This means that it is now an established framework, so that manufacturers around the world can begin to create standardized equipment that can transmit up to 100 watts. A typical USB connector can deliver between 2.5 and 4.5 watts, so the new standard offers a significant power upgrade.
The end of proprietary chargers
Up to 4.5 watts is not too much to external devices, like hard drives, monitors, optical devices and audio systems. Several of these devices need today two USB connectors to get enough power to operate, which may now come to an end. If the maximum power of 100 watts can be delivered through a single cable. NAS’s and other large storage devices, and displays that are far more powerful than the USB screens that exist today will all become possible.
The new power standard is also arranged so that the equipment can not only drain power from your computer – it can also deliver power back in the other direction. Then you can connect an extra external battery to your laptop via the new USB type port to charge the machine as well as take charge from the laptop.
