Very Soon USB 3.0 Chargers Will Be Powering Your Notebooks
In light of recent news from the USB 3.0 Promoter Group that USB 3.0 now has the capacity to transmit power much larger than the traditional 5V specification, some of those in the technology industry have been suggesting great ideas aimed at making the most out of the power of USB 3.0.
The more commonplace ones talk of single-cable external hard drives, quick charge options for smartphones, and an all-in-one cable for users on the go. The most interesting idea to surface, however, is the possibility of having USB power bricks that will replace the current A/C adapters that laptops are charged with. If this happens soon, everyone may just bear witness to an influential standardization of notebook chargers that can put an end to the exorbitant prices of brand-specific adapters and diminished confusion about notebook-to-charger compatibility.
The maximum power that current USB 3.0 cables can provide is set at 4.5 Watts, 2 Watts more than the amount of power that USB 2.0 delivers. But developers from the USB Promoter Group say that USB 3.0′s new Power Delivery certification can eventually handle power as high as 100 Watts. That’s more than enough to power even the hungriest laptops!
How will USB 3.0 handle this? Instead of making cables for varying power capacities, USB 3.0 developers will be designing “intelligent” cables that can detect the power needed by each device then deliver power accordingly. This means that you don’t have to worry about frying your gadgets or packing a cord for each of them. Development of these USB 3.0 cables will still take some time. The most optimistic projection for a USB-powered laptop is set at several quarters away (a vague estimation that can range from six months to a full year).
Since things tend to play out longer in real time, the idea of USB 3.0-powered laptops dwells comfortably in the future. And if the adoption of USB 3.0 is any indication, mainstream support could take a really long time. In the meantime, it won’t do any harm to think about the convenience that will, sooner or later, be available to the user.
