VOOC
Oppo VOOC (Voltage Open Loop Multi-step Constant-Current Charging), also known as Warp Charge on OnePlus devices and Dart Charge on Realme devices, is a proprietary rapid-charge technology created by BBK Electronics. In contrast to USB Power Delivery and Qualcomm Quick Charge technology, which increases the voltage during fast charging, VOOC uses a higher current than standard USB charging. The VOOC Flash Charge circuit technology reportedly lowers the temperature of the charging adapter, and creates an interface from the adapter to the phone, which, OPPO claims, improves the speed and safety of the charge. VOOC 2.0 has been licensed to OnePlus as the Dash Charge technology. A single-cell, 30-watt (5 V/6 A) version of VOOC 4.0 has also been licensed to OnePlus as Warp Charge. OnePlus does not market its phones as VOOC-compatible despite the fact that VOOC 2.0 and Dash are compatible. , VOOC has been licensed to 14 other corporations, most of which are in the phone charging and po ...

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 ...

Charge Pump
A charge pump is a kind of DC-to-DC converter that uses capacitors for energetic charge storage to raise or lower voltage. Charge-pump circuits are capable of high efficiencies, sometimes as high as 90–95%, while being electrically simple circuits. Description Charge pumps use some form of switching device to control the connection of a supply voltage across a load through a capacitor. In a two stage cycle, in the first stage a capacitor is connected across the supply, charging it to that same voltage. In the second stage the circuit is reconfigured so that the capacitor is in series with the supply and the load. This doubles the voltage across the load - the sum of the original supply and the capacitor voltages. The pulsing nature of the higher voltage switched output is often smoothed by the use of an output capacitor. An external or secondary circuit drives the switching, typically at tens of kilohertz up to several megahertz. The high frequency minimizes the amount of ...

USB Power Delivery
The initial versions of the USB standard specified connectors that were easy to use and that would have acceptable life spans; revisions of the standard added smaller connectors useful for compact portable devices. Higher-speed development of the USB standard gave rise to another family of connectors to permit additional data paths. All versions of USB specify cable properties; version 3.x cables include additional data paths. The USB standard included power supply to peripheral devices; modern versions of the standard extend the power delivery limits for battery charging and devices requiring up to 100 watts. USB has been selected as the standard charging format for many mobile phones, reducing the proliferation of proprietary chargers. Connectors The three sizes of USB connectors are the default or ''standard'' format intended for desktop or portable equipment, the ''mini'' intended for mobile equipment, which was deprecated when it was replaced by the thinner ''micro'' si ...

Open Source
Open source is source code that is made freely available for possible modification and redistribution. Products include permission to use the source code, design documents, or content of the product. The open-source model is a decentralized software development model that encourages open collaboration. A main principle of open-source software development is peer production, with products such as source code, blueprints, and documentation freely available to the public. The open-source movement in software began as a response to the limitations of proprietary code. The model is used for projects such as in open-source appropriate technology, and open-source drug discovery. Open source promotes universal access via an open-source or free license to a product's design or blueprint, and universal redistribution of that design or blueprint. Before the phrase ''open source'' became widely adopted, developers and producers have used a variety of other terms. ''Open source'' ga ...
