The USB PD specification provides the ability for 5 V devices to draw more than (the USB battery-charging specification limit of) 7.5 W of power from USB "PD-aware" ports when using PD-aware USB cables. The specification also allows USB PD ports to provide even greater power at higher voltages over PD-aware cables – up to 36 W at 12 V and 60 ...
Apple Lightning to USB-A cable. Lightning is an 8-pin digital connector. Unlike the 30-pin dock connector it replaced (and USB Type-A and -B connectors), it is reversible. [20] Most Lightning devices only supported USB 2.0, which has a maximum transfer speed of 480 Mbit/s or 60 MB/s. With USB 2.0, only one lane is in use at a time.
A USB cable, by definition, has a plug on each end—one A (or C) and one B (or C)—and the corresponding receptacle is usually on a computer or electronic device. The mini and micro formats may connect to an AB receptacle, which accepts either an A or a B plug, that plug determining the behavior of the receptacle.
Whereas earlier USB cables had a host end A and a peripheral device end B, a USB-C cable connects either way; and for interoperation with older equipment, there are cables with a Type-C plug at one end and either a Type-A (host) or a Type-B (peripheral device) plug at the other. The designation "C" refers only to the connector's physical ...
Charging docks supply power, and do not include a host device or data pins, allowing any capable USB device to charge or operate from a standard USB cable. Charging cables provide power connections but not data. In a charge-only cable, the data wires are shorted at the device end; otherwise, the device may reject the charger as unsuitable.
Common external power supply and the USB-A and USB Micro-B ends of the detachable cable. The common external power supply ( Common EPS) was a European Commission (EC) specification for a universal charger for smartphones sold within the European Union. The specification included the use of a USB Micro-B connector and adherence to the USB ...
AC adapter. A "wall-wart" type AC adapter for a household game console. The output has a barrel connector. "Power brick" in-line configuration, with detachable AC cord and NEMA 1-15 plug. An AC adapter or AC/DC adapter (also called a wall charger, power adapter, power brick, or wall wart) [1] is a type of external power supply, often enclosed ...
USB 3.0 also introduced a new Micro-B cable plug, which consists of a standard USB 1.x/2.0 Micro-B cable plug, with an additional 5-pin plug "stacked" beside it. That way, the USB 3.0 Micro-B host receptacle preserves its backward compatibility with the USB 1.x/2.0 Micro-B cable plug, allowing devices with USB 3.0 Micro-B ports to run at USB 2. ...
