Will USB Power Delivery could make chargers obsolete?
“USB Power Delivery enables a path to greatly reduce electronic waste by eliminating proprietary, platform-specific chargers,” said Brad Saunders, USB 3.0 Promoter Group Chairman. “We envision a significant move toward universal charging based on this specification, most notably for charging notebook PCs using standardized USB power bricks or when connected to USB hubs and desktop displays that integrate USB Power Delivery capabilities.”
The USB Promoter Group has announced new USB Energy Delivery specifications (PDF) for the USB connectivity interface, which will allow USB ports to provide up to 100W of energy and get rid of the need to have for proprietary energy adapters to charge laptops and also other connected electronics devices.
In its 300-plus web page specification document (14.5MB ZIP), the group provides comprehensive particulars about the design and style and implementation of the new requirements, that will be backward compatible with all the USB 2.0 common.
While existing USB cables are capable of charging devices like cameras and phones, too as powering external tough disks, the new standard aims additional at “a one cable to rule them all” flexible energy management ecosystem, whereby all your electronics devices may be powered by a single USB lead.
The move could potentially make current notebook charging options obsolete, as well as energy displays solely via a computer’s USB port. Additionally people could use a single “powered” cable connected to a USB hub to charge multiple devices at the identical time.
In an effort to guarantee cables are not overloaded, the group has defined five diverse profiles with differing levels of present, which work using “USB Power Delivery Certified cables” as well as conventional USB cables, although the latter won’t be capable of delivering the higher levels of present.
- Profile 1 capable of supplying 5V @ 2.0A
- Profile 2 is capable of supplying 5V @ 2.0A or 12v @1.5A
- Profile 3 is capable of supplying 5V @ 2.0A, 12V @ 3A
- Profile 4 is capable of supplying 5V @ 2.0A, 12V and 20V at 3A
- Profile 5 is capable of supplying 5V @ 2.0A, 12V and 20V at 5A
Certainly one of the only significant non-Tablet or Ultrabook related stories at Computex this year was Intel’s coming out celebration of Thunderbolt on the Computer.
As Intel’s peripheral connectivity protocol is capable of 10Gbps of data throughput, it was marketed at Computex as the USB 3.0 killer. The USB protocol cannot beat Thunderbolt on speed throughput, but the consortium behind the connectivity protocol have various suggestions on how you can fend off Thunderbolt: Power delivery.
Meanwhile with USB 3.0 Promoter Group announced a new USB power delivery specification that would allow up to 100W of power delivery via special enhanced USB cables. Although USB 3.0 cannot move as much data as Thunderbolt, meaning it will not have the ability to data chain, the increased power capacity provides an fascinating competitive benefit for the protocol. Ultimately, the marketplace will that is the successful next generation peripheral connectivity protocol.
