IEEE P1823 was a proposed global standard for a universal power adapter for mobile devices (UPAMD) that require between 10 W and 240 W. E.g., Laptops, larger tablets and other mobile devices that can require much more power than the (non-Power Delivery) USB battery charging specification limit of 7.5 W at 5 V. [25]
The Standards Association of the Institute of Electrical and Electronics Engineers (IEEE) approved the Universal Power Adapter for Mobile Devices working group on June 17, 2010. [7] The project was sponsored by the Microprocessor Standards Committee of the IEEE Computer Society. On 15 May 2015 the standard was published as IEEE Std 1823-2015. [8]
A passive electric power adapter, sometimes called a travel plug or travel adapter, allows using a plug from one region with a foreign socket. As other countries supply 120-volt, 60 Hz AC, using a travel adapter in a country with a different supply poses a safety hazard if the connected device does not support both input voltages.
Subsequently, the trademark has been expanded to include not just the proprietary 15 V DC connector but also the 120 V 60 Hz AC in-seat power (and video entertainment) systems. American Airlines uses EmPower 120 V AC outlets (standard 2 prong plus ground) on their newer 737s. Many laptops will not function properly at 75 W.
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 in a case similar to an AC plug. [2] AC adapters deliver electric power to devices that lack internal components to draw voltage and power from mains power themselves.
However, to facilitate migration from wired to wireless, WUSB introduced a new Device Wire Adapter (DWA) class. Sometimes referred to as a "WUSB hub", a DWA allows existing USB 2.0 devices to be used wirelessly with a WUSB host. WUSB host capability can be added to existing PCs through the use of a Host Wire Adapter (HWA). The HWA is a USB 2.0 ...
