Quick Charge
Quick Charge (QC) is a proprietary battery charging protocol developed by Qualcomm, used for managing power delivered over USB, mainly by communicating to the power supply and negotiating a voltage. Quick Charge is supported by devices such as mobile phones which runs on Qualcomm SoCs, and by some chargers; both device and charger must support QC, otherwise QC charging is not attained. It charges batteries in devices faster than standard USB allows by increasing the output voltage supplied by the USB charger, while adopting techniques to prevent the battery damage caused by uncontrolled fast charging and regulating the incoming voltage internally. Usually, chargers supporting Quick Charge 2.0 and later are wall adaptors, but it is implemented on some in-car chargers, and some power banks use it to both receive and deliver charge. Quick Charge is also used by other manufacturers' proprietary rapid-charging systems. Details Quick Charge is a proprietary technology that allows ...

Standby Mode
Sleep mode (or suspend to RAM) is a low power mode for electronic devices such as computers, televisions, and remote controlled devices. These modes save significantly on electrical consumption compared to leaving a device fully on and, upon resume, allow the user to avoid having to reissue instructions or to wait for a machine to reboot. Many devices signify this power mode with a pulsed or red colored LED power light. Computers In computers, entering a sleep state is roughly equivalent to "pausing" the state of the machine. When restored, the operation continues from the same point, having the same applications and files open. Sleep Sleep mode has gone by various names, including ''Stand By'', ''Suspend'' and ''Suspend to RAM''. Machine state is held in RAM and, when placed in sleep mode, the computer cuts power to unneeded subsystems and places the RAM into a minimum power state, just sufficient to retain its data. Because of the large power saving, most laptops automaticall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wireless Power Consortium
The Wireless Power Consortium (WPC) is a multinational technology consortium formed on December 17, 2008, and based in Piscataway, New Jersey. Its mission is to create and promote wide market adoption of its interface standards Qi, Ki Cordless Kitchen, and Qi Medium Power for inductive charging. It is an open membership of Asian, European, and American companies, working toward the global standardization of wireless charging technology. The Wireless Power Consortium was started by Fulton Innovation, a 100% subsidiary of Alticor, parent company of Amway. The original motivation was to power a portable water purifier, sold by Amway, called eSpring, for which the wireless power transfer technology called eCoupled was created. On Nov 26, 2008 Fulton Innovation released "The Base Spec: Low Power Specification Guide for Partnered Product Development, Revision 0.9". Buoyed by the acquired intellectual property of a bankrupt University of Cambridge spin-out called Splashpower, in an a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Qi (standard)
Qi (pronounced ; from the Chinese word 气 qi; traditional Chinese: 氣) is an open interface standard that defines wireless power transfer using inductive charging over distances of up to 4 cm (1.6 inches). It is developed by the Wireless Power Consortium. The system uses a charging pad and a compatible device, which is placed on top of the pad, charging via resonant inductive coupling. As of February 2020, there are 488 manufacturers working with the standard including Apple, Asus, Google, Huawei, LG Electronics, Samsung, Xiaomi, and Sony. First released in 2008, the Qi standard was incorporated into more than 200 smartphones, tablets and other devices by 2017. Design left, Fig. 1-1 Devices that operate using the Qi standard rely on electromagnetic induction between planar coils. A Qi system consists of two types of devices – the Base Station, which is connected to a power source and provides inductive power, and Mobile Devices, which consume inductive power. T ...

XDA Developers
XDA Developers (also known simply as XDA; often stylized as xda-developers) is a mobile software development community launched on 20 December 2002. Although discussion primarily revolves around Android, members also talk about many other operating systems and mobile development topics. The "X" represents convergence of voice and information/data within one product; the "DA" stands for "Digital Assistant", as in PDA. The name of XDA Developers is derived from it. Many software and hardware hacks, rooting methods, and other phone and tablet specific tweaks originate from the members of the XDA Forum. XDA Developers also hosts the XDA Portal, a source for Android and mobile phone development news, as well as XDA Labs (shut down in 2020), an Android app and repository that acts as a third-party application provider. They were launched in 2010 and 2016, respectively. Montreal based Valnet Inc. acquired Xda-Developers along with four other websites, Pocketnow, AppAdvice, Backyard ...

Programmable Power Supply
A power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters. Some power supplies are separate standalone pieces of equipment, while others are built into the load appliances that they power. Examples of the latter include power supplies found in desktop computers and consumer electronics devices. Other functions that power supplies may perform include limiting the current drawn by the load to safe levels, shutting off the current in the event of an electrical fault, power conditioning to prevent electronic noise or voltage surges on the input from reaching the load, power-factor correction, and storing energy so it can continue to power the load in the event of a temporary interruption in the source power (uninterruptible ...

USB PD PPS
Universal Serial Bus (USB) is an industry standard that establishes specifications for cables, connectors and protocols for connection, communication and power supply (interfacing) between computers, peripherals and other computers. A broad variety of USB hardware exists, including 14 different connector types, of which USB-C is the most recent and the only one not currently deprecated. First released in 1996, the USB standards are maintained by the USB Implementers Forum (USB-IF). The four generations of USB are: USB 1.''x'', USB 2.0, USB 3.''x'', and USB4. Overview USB was designed to standardize the connection of peripherals to personal computers, both to communicate with and to supply electric power. It has largely replaced interfaces such as serial ports and parallel ports, and has become commonplace on a wide range of devices. Examples of peripherals that are connected via USB include computer keyboards and mice, video cameras, printers, portable media players ...

USB-C
USB-C (properly known as USB Type-C) is a 24-pin USB connector system with a rotationally symmetrical connector. The designation C refers only to the connector's physical configuration or form factor and should not be confused with the connector's specific capabilities, which are designated by its transfer specifications (such as USB 3.2). A notable feature of the USB-C connector is its ''reversibility''; a plug may be inserted into a receptacle in either orientation. The ''USB Type-C Specification 1.0'' was published by the USB Implementers Forum (USB-IF) and was finalized in August 2014. It was developed at roughly the same time as the USB 3.1 specification. In July 2016, it was adopted by the IEC as "IEC 62680-1-3". A device with a Type-C connector does not necessarily implement USB, USB Power Delivery, or any Alternate Mode: the Type-C connector is common to several technologies while mandating only a few of them. USB 3.2, released in September 2017, repla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
