PD (Power Delivery) 1.0/2.0/3.0/3.1/3.2

 

This charging protocol is designed specifically for USB-C to USB-C cables (USB3.1 standard).

Some important facts:

  • Power can flow in both directions.

  • Allows low-power devices to negotiate for only the power they require.

  • It's the backbone for the implementation of many other fast charging standards like PPS, QC4/QC5 etc.

  • PPS as well as AVS are extensions of PD charging standard allowing gradually changing charging voltage and current.

  • PD3.1 brought EPR (Extended Power Range) mode allowing charging at 5A and voltage above 20V. Entering in EPR mode requires an EPR cable with e-maker chip which sends to a charger cable charging protocol parameters. Power range up to 100W starts calling SPR (Standard Power Range).

  • USB PD3.1 brings support for Display Port 1.4a video signals enabling devices to transmit high-quality audio and video signals up to 8K resolution over a single USB-C cable.

USB-PD PPS (Programmable Power Supply), USB-PD AVS (Adjustable Voltage Supply) 

 

The PPS was implemented with USB PD3.0. 

Thanks to the PPS, devices can gradually adjust the current and voltage in such a way that the device receives the best possible charging supply. PPS also ensures that you charge efficiently, generate less heat, and, as a result, maintain the health of your battery.

It has variable voltages instead of the fixed 5V/9V/15V/20V profiles in USB-PD.  The voltage varies from 3.3 to 21 V in 20 mV (0.02V) steps and a current is specified in 50 mA steps to facilitate constant-voltage and constant-current charging. Data about changing supplying power is sent between the charger and the charging device every 10 seconds.

Charging modes for the latest PD3.2 PPS:

  • 5-11.0V - 3A - up to 33W

  • 5-16.0V - 3A - up to 48W

  • 5-21.0V - 3A - up to 60W

  • 5-21.0V - 5A - up to 100W (requires 5A cable)

​

The AVS was implemented with USB PD3.1 and extended with PD3.2 allowing it to work within the standard power range (SPR) below 100W, down to a minimum of 9V. AVS is similar to PPS in terms of function, but the difference is that AVS does not support Current Limit operation, and the output voltage is adjusted in a unit step of 100mV (20mV for PPS).

AVS charging modes for the latest PD3.2:

  • (SPR AVS) 9-15V - 3A (27-45W)

  • (SPR AVS) 9-20V - 3A (45-60W)

  • (SPR AVS) 9-20V - 5A (60-100W) - requires 5A cable

  • (EPR AVS) 15-28V - 5A (up to 140W) - requires 5A EPR cable with e-maker chip

  • (EPR AVS) 15-36V - 5A (up to 180W) - requires 5A EPR cable with e-maker chip

  • (EPR AVS) 15-48V - 5A (up to 240W) - requires 5A EPR cable with e-maker chip

​

Other facts:

  • Qualcomm Quick Charge 5 is USB-PD PPS

  • Any USB-IF Certified Fast Charger must include PPS

  • MediaTek's Pump Express (PE) 4.0 also relies on USB-PD PPS

  • It is important to know that many chargers that claim fast charging functionality often do not achieve the top charging speed for devices from Samsung, for example. Samsung Galaxy devices (S20 and above) require a charger that has PPS technology to use Super Fast Charging (SFC)

  • Official Power delivery documentation

  • Smartphone manufacturer Nubia uses a modification of the PPS protocol to achieve a charge of up to 165W (3.6-20V/8.25A), which requires the use of a proprietary charger and proprietary UsbC-UsbC 9A cable. The Nubia charger supports standard PD and PPS protocols, while the Nubia smartphone can be charged by some third-party chargers via PD/PPS protocols (up to 90W).

OPPO VOOC, SuperVOOC. OnePlus DASH/WARP charge. Realme SuperDart/UltraDart Charge

 

VOOC stands for Voltage Open Loop Multi-step Constant-Current Charging. It is a proprietary fast-charging method released in 2014 by Oppo.

The technology is used in brands of mobile products under the umbrella of its parent company BBK Electronics. (OPPO, OnePlus, Realme)

Unlike high-voltage/low-current schemes (QC or PE for example), the VOOC series has consistently used a low-voltage, high-current fast charging approach. The core of VOOC is to input current directly from the charger into the phone's battery at a relatively low voltage (5V or lower), eliminating the need for internal high-to-low voltage conversion within the phone (the voltage of the built-in lithium-ion battery in the phone is generally around 4.2~4.4V). This process enhances efficiency and reduces heat generation (in comparison with other fast charging protocols). Additionally, VOOC often incorporates real-time temperature sensors, making it more advantageous in terms of safety.

OPPO increased the contact pins of the Micro USB interface and used custom chargers to implement high-current fast charging.

VOOC and SuperVOOC require a compatible adapter and a cable.

VOOC vs SuperVOOC.

Both fast charge technologies have a common idea of low voltage-high current and a common solution however SuperVOOC usually is more advanced, relying on top-notch components, charging algorithms, charging 2 batteries in a series approach, and additional chips and sensors. From a marketing standpoint, SuperVOOC is positioned as a solution for top-tier smartphones.

​

OPPO in July 2020 introduced 125W Flash Charger. It supports the charging mainstream protocols of 125W PPS, 65W PD, 65W SuperVOOC, 30W VOOC, 36W QC. It also supports a charging scheme from adapter to smartphone up to 20V/6.25A which is converted to 10V/12.5A in smartphone in order to charge a battery. The technology also added temperature sensors to enhance safety protection during the charging time. High current charging requires using improved battery cells with low internal resistance which can handle up to 6C charge (12.5A) connected in a sequence (2S formation). USB connector has been improved in order to withstand such current level.

SuperVOOC 150W Flash charge/UltraDart. 20V/7.5A from charger converted to 10V/15A in smartphone and then split by 5V15A between 2 batteries in smartphone. Charger is compatible with USB PD and PPS protocols.

​

Charging protocols:

Note:

  • OPPO VOOC, OnePlus (DASH), and Realme all belong to the VOOC series, and accessories from these three brands are mutually and downward compatible however it's not guaranteed in the future.

  • SuperVOOC 1.0 chargers may charge VOOC/Dash/Warp30 devices but no more than half of the speed as SuperVOOC design is supposed to have 2 batteries in a smartphone and VOOC/Warp compatible smartphones have only one cell battery.

  • Some Oppo smartphones are capable use USB PD chargers.

  • SuperVOOC adapters do not charge other devices with USB PD protocol.

  • SuperVOOC charging cables are backward compatible with older technology generations (VOOC, Dash, Warp)

  • SuperVOOC UsbA-UsbC proprietary cables have an additional signal pin on the UsbA side and larger pins for high current transfer (up to 9.1A).

  • Realme announced Supersonic fast charging technology with 320w charging speed, however it based not on SuperVOOC but on UFCS charging technology.

Spreadtrum SFCP

​

The SFCP protocol is a fast charging protocol launched by Spreadtrum chipmaker back in 2016, which can theoretically provide a variable voltage of 5V-20V. The protocol did not become popular and very few products support it. As an example Sharge 100W charger supports SFCP at 5V, 9V and 12V voltage levels

PoweredUSB, also known as Retail USB, USB PlusPower, USB +Power, and USB Power Plus.

It allows for higher-power devices to obtain power through their USB host instead of requiring an independent power supply or external AC adapter.

It is mostly used in point-of-sale equipment, such as receipt printers, touch monitors, and barcode readers.

There are different power shapes and color-coded versions of plugs:

  • Grey/Yellow - 5V (7.5-30 W)

  • Teal - 12V (18-72 W)

  • Red - 24V (55.2-144 W)

  • Violet (alternative) - 19V

  • Red (alternative) - 25V

  • Black - alternative for any voltages higher than 5 V
