USB's Battery Charging Standard Gains Adoption

BELLEVUE, Wash.--(BUSINESS WIRE)-- A new generation of USB hubs and devices is enabling:

• Use of a standard full-function USB hub for charging
• Fast charging even when the attached computer is off
• Charging up to 3x faster than USB 2.0's old maximum rate

To date, USB charging has been a source of enormous confusion. Consumers expected to plug any USB device into any USB hub, and for those devices to charge. Unfortunately, USB 2.0 as originally designed does not allow devices to pull more than 100mA without software negotiation, and only 500mA with.

100mA isn't enough for most devices to charge. And to achieve charge rates higher than 500mA, popular devices such as the Apple iPad™ have introduced proprietary hardware negotiation.

This has left consumers with bins full of device-specific chargers. The USB Battery Charging specification (BC 1.1 and later) aims to fix that.

For example with the new Amazon Kindle Fire™, a micro USB cable, and Plugable’s new USB2-HUB4BC 4-port USB hub, the Fire will charge even with the computer off, and charge faster than USB's old maximum of 500mA.

For less than the cost of a dedicated charger, it's possible to buy a hub that supports both charging and syncing, and isn't tied to any one device.

The Plugable USB2-HUB4BC is available on Amazon now for $19.95 at http://www.amazon.com/dp/B005P2BY5I/.
