The intent is to permit uniformly charging laptops, tablets, USB-powered disks and similarly higher-power consumer electronics, as a natural extension of existing European and Chinese mobile telephone charging standards. This may also affect the way electric power used for small devices is transmitted and used in both residential and public buildings. [61] [62] The standard is designed to coexist with the previous USB Battery Charging specification. [63]Europe gets universal cellphone charger in 2010". Wired. June 13, 2009. Archived from the original on August 18, 2010 . Retrieved June 22, 2010. A bus-powered hub is a high-power device providing low-power ports. It draws 1 unit load for the hub controller and 1 unit load for each of at most 4 ports. The hub may also have some non-removable functions in place of ports. A self-powered hub is a device that provides high-power ports by supplementing the power supply from the host with its own external supply. Optionally, the hub controller may draw power for its operation as a low-power device, but all high-power ports must draw from the hub's self-power.

Some USB devices require more power than is permitted by the specifications for a single port. This is common for external hard and optical disc drives, and generally for devices with motors or lamps. Such devices can use an external power supply, which is allowed by the standard, or use a dual-input USB cable, one input of which is for power and data transfer, the other solely for power, which makes the device a non-standard USB device. Some USB ports and external hubs can, in practice, supply more power to USB devices than required by the specification but a standard-compliant device may not depend on this.

The USB1.1 standard specifies that a standard cable can have a maximum length of 5 meters (16ft 5in) with devices operating at full speed (12Mbit/s), and a maximum length of 3 meters (9ft 10in) with devices operating at low speed (1.5Mbit/s).

In the case of sat nav systems, mini USB cables provide a reliable solution for charging the device and ensuring continuous power during navigation. They allow users to keep their sat nav devices charged and ready for use, ensuring uninterrupted guidance on the road. USB 2.0 uses two wires for power (V BUS and GND), and two for differential serial data signals. Mini and micro connectors have their GND connections moved from pin #4 to pin #5, while their pin #4 serves as an ID pin for the On-The-Go host/client identification. [6]There are so-called cables with A plugs on both ends, which may be valid if the "cable" includes, for example, a USB host-to-host transfer device with two ports. [3] This is, by definition, a device with two logical B ports, each with a captive cable, not a cable with two A ends.

a b Howse, Brett (August 12, 2014). "USB Type-C Connector Specifications Finalized". Archived from the original on December 28, 2014 . Retrieved December 28, 2014. In July 2012, the USB Promoters Group announced the finalization of the USB Power Delivery ( USB-PD) specification (USB PD rev. 1), an extension that specifies using certified PD aware USB cables with standard USB Type-A and Type-B connectors to deliver increased power (more than 7.5W) to devices with greater power demands. (USB-PD A and B plugs have a mechanical mark while Micro plugs have a resistor or capacitor attached to the ID pin indicating the cable capability.) USB-PD Devices can request higher currents and supply voltages from compliant hosts—up to 2A at 5V (for a power consumption of up to 10W), and optionally up to 3A or 5A at either 12V (36W or 60W) or 20V (60W or 100W). [59] In all cases, both host-to-device and device-to-host configurations are supported. [60] The D± signals used by low, full, and high speed are carried over a twisted pair (typically unshielded) to reduce noise and crosstalk. SuperSpeed uses separate transmit and receive differential pairs, which additionally require shielding (typically, shielded twisted pair but twinax is also mentioned by the specification). Thus, to support SuperSpeed data transmission, cables contain twice as many wires and are larger in diameter. [34] What Is the USB 3.0 Cable Difference". Hantat. May 18, 2009.

Portable devices having a USB On-The-Go port may want to charge and access a USB peripheral simultaneously, yet having only a single port (both due to On-The-Go and space requirement) prevents this. Accessory charging adapters (ACA) are devices that provide portable charging power to an On-The-Go connection between host and peripheral. Nice Micro-USB adapter Apple, now sell it everywhere", Giga om, 5 October 2011, archived from the original on 26 August 2012 As of USB Power Delivery specification revision2.0, version1.2, the six fixed power profiles for power sources have been deprecated. [67] USB PD Power Rules replace power profiles, defining four normative voltage levels at 5V, 9V, 15V, and 20V. Instead of six fixed profiles, power supplies may support any maximum source output power from 0.5W to 100W.
