Retractable USB Cable
Highlights:At home or on the road, don't be bothered by a clutter of cables. Our retractable cable eliminates the mess of cables that can accumulate on your desk or in your notebook bag.A unique ratcheting system adjusts the amount of visible cable at any given time. Whether you need a little or a lot, just pull the cable from both sides of the housing, and adjust it to fit your application. When you are finished, pull the cable again, and it retracts back into the housing, out of your way.Features:- Supports USB 2.0 data transfers- Ratcheting system adjusts the amount of cable to fit your application- Eliminate clutter on your desk and in your notebook bag- Length (approx): 0.75m (30 inches) max., 0.1m (4 inches)Package Contents:- Retractable USB Cable (USB A Male - USB Mini-B Male) x 1Packaging:- PolybagNote:- May use to sync or charge(or sync and charge, depending on your devices) your devices with a Micro USB port, e.g. Motorola V8, Nokia N810 Internet Tablet ... with your PC- The product to be shipped may be a little different in color and outline to the picture shown above but the functionality will remain 100% good.- Sometimes people like to call a Male connector as a Plug connector, a Female connector as a receptacle or Jack connector.- To be shipped in bulk pack
Version historyPrereleasesThe USB standard evolved through several versions before its official release in 1995:USB 0.7: Released in November 1994.USB 0.8: Released in December 1994.USB 0.9: Released in April 1995.USB 0.99: Released in August 1995.USB 1.0 Release Candidate: Released in November 1995.
USB 1.0USB 1.0: Released in January 1996.Specified data rates of 1.5 Mbit/s (Low-Bandwidth) and 12 Mbit/s (Full-Bandwidth). Does not allow for extension cables or pass-through monitors (due to timing and power limitations). Few such devices actually made it to market.USB 1.1: Released in August 1998.Fixed problems identified in 1.0, mostly relating to hubs. Earliest revision to be widely adopted.
USB 2.0USB 2.0: Released in April 2000. Added higher maximum signaling rate of 480 Mbit/s (effective throughput up to 35 MB/s) (now called "Hi-Speed"). Further modifications to the USB specification have been done via Engineering Change Notices (ECN). The most important of these ECNs are included into the USB 2.0 specification package available from USB.org[11]:Mini-A and Mini-B Connector ECN: Released in October 2000.Specifications for Mini-A and B plug and receptacle. Also receptacle that accepts both plugs for On-The-Go. These should not be confused with Micro-B plug and receptacle.Errata as of December 2000: Released in December 2000.Pull-up/Pull-down Resistors ECN: Released in May 2002.Errata as of May 2002: Released in May 2002.Interface Associations ECN: Released in May 2003.New standard descriptor was added that allows multiple interfaces to be associated with a single device function.Rounded Chamfer ECN: Released in October 2003.A recommended, compatible change to Mini-B plugs that results in longer lasting connectors.Unicode ECN: Released in February 2005.This ECN specifies that strings are encoded using UTF-16LE. USB 2.0 did specify that Unicode is to be used but it did not specify the encoding.Inter-Chip USB Supplement: Released in March 2006.On-The-Go Supplement 1.3: Released in December 2006.USB On-The-Go makes it possible for two USB devices to communicate with each other without requiring a separate USB host. In practice, one of the USB devices acts as a host for the other device.Battery Charging Specification 1.1: Released in March 2007 (Updated 15 Apr 2009).Adds support for dedicated chargers (power supplies with USB connectors), host chargers (USB hosts that can act as chargers) and the No Dead Battery provision which allows devices to temporarily draw 100 mA current after they have been attached. If a USB device is connected to dedicated charger, maximum current drawn by the device may be as high as 1.8 A. (Note that this document is not distributed with USB 2.0 specification package only USB 3.0 and USB On-The-Go.)Micro-USB Cables and Connectors Specification 1.01: Released in April 2007.Link Power Management Addendum ECN: Released in July 2007.This adds a new power state between enabled and suspended states. Device in this state is not required to reduce its power consumption. However, switching between enabled and sleep states is much faster than switching between enabled and suspended states, which allows devices to sleep while idle.Battery Charging Specification 1.2[12]: Released in December 2010.Several changes and increasing limits including allowing 1.5A on charging ports for unconfigured devices, allowing High Speed communication while having a current up to 1.5A and allowing a maximum current of 5A.
USB 3.0Main article: USB 3.0USB 3.0 was released in November 2008. The standard specifies a maximum transmission speed of up to 5 Gbit/s (625 MB/s), which is more than 10 times as fast as USB 2.0 (480 Mbit/s, or 60 MB/s), although this speed is typically only achieved using powerful professional grade or developmental equipment. USB 3.0 reduces the time required for data transmission, reduces power consumption, and is backward compatible with USB 2.0. The USB 3.0 Promoter Group announced on 17 November 2008 that the specification of version 3.0 had been completed and had made the transition to the USB Implementers Forum (USB-IF), the managing body of USB specifications.[13] This move effectively opened the specification to hardware developers for implementation in products. The new "SuperSpeed" bus provides a fourth transfer mode at 5.0 Gbit/s (raw data rate), in addition to the modes supported by earlier versions. The payload throughput is 4 Gbit/s (using 8b/10b encoding), and the specification considers it reasonable to achieve around 3.2 Gbit/s (0.4 GB/s or 400 MB/s), which should increase with future hardware advances. Communication is full-duplex during SuperSpeed; in the modes supported previously, by 1.x and 2.0, communication is half-duplex, with direction controlled by the host.Battery Charging Specification 1.2[12]: released in December 2010. Several changes and increasing limits including allowing 1.5A on charging ports for unconfigured devices, allowing High Speed communication while supplying a current up to 1.5A, and allowing a maximum current of 5A.
