Understanding Different Charging Protocols

By Anan Sadh - There are many different types of fast charging protocols such as OPPO’s open VOOC Flash Charge,  OnePlus WARP / Dash Realme DART charge, Qualcomm’s Quick Charge fast charging & PPS / PD Fast Charging. Some of these are proprietory ( Flash, Dash, Warp, Dart, VooC) & QC,while some are open platforms ( PD & PPS)

Nowadays, smart phones have quick charging between 18W to 65W power, with charge times going from 30 minutes to a little more than 60 minutes. Let’s broadly understand the differences.

  1. Qualcomm’s Quick Charge QC3.0 / 4.0

Qualcomm’s QC Quick Charge is very familiar today & it is a representative of high-voltage fast charge. It was first launched in 2013 when the highest power was 10W (5V/2A). By QC 3.0, the power increased to 36W, & now it supports 200mV step voltage regulation, which is no longer a fixed set of voltage & current. QC 4 supports step voltage regulation down to 20mV and a current adjustment of 50mA. Moreover, it also supports USB PD+PPS.

Quick Charge 5 is world's Quickest Charging Solution conveying surprising charging rates of up to 0 to 50% in just five minutes while empowering new battery innovation, embellishments, & well-being features. 

  1. PD Fast Charging

PD fast charging delivers up to 100W& is suitable for all types of devices beyond smart phones, including laptops, as they have a USB-C port. This is currently the most extensive charging protocol.

Currently, there are commonly USB PD 2.0, USB PD 3.0, & USB PD 3.0 (PPS), the former two belong to high-voltage fast charging, and the PPS of the latter belongs to a branch of PD 3.0, which is known as Programmable Power Supply. It incorporates Qualcomm QC, FCP, VOOC, & other fast charging protocols, supporting 20mV and 50mA step adjustments more accurately.

Apple iPhones from the iPhone 8 through the iPhone 14 models imply USB-PD, the same industry standard used by the iPad Pro, the 12-inch MacBook, Google’s Chromebook Pixel, & Lenovo’s X1 Carbon.

USB-PD is an open platform and is rapidly being adopted by many manufacturers. 

  1. Open VOOC Technology

Oppo has licensed the Open VOOC technology to various brands & it has been marketed under various names. Example OnePlus Dash &  Warp Charging works only with OnePlus phones, well-matched wall adapters & cables. Warp Charge cables are slightly thicker to accommodate the extra heat being generated. It’s based on Oppo’s VOOC (Voltage Open Multi-Step Constant-Current Charging) system and is a star feature in the OnePlus 6T and every other OnePlus phone back to the OnePlus 3. Oppo has also developed the much faster Super VOOC, but it’s only available in a handful of phones like the Oppo RX17 Pro. Vivo. 

  1. Huawei SuperCharge

SuperCharge, Huawei’s proprietary charging standard, is built into phones like the Huawei P40 Pro, Huawei P30 Pro, Huawei Mate 20 Pro, and the Huawei P10. It’s a bit like Quick Charge in that it uses higher-than-average voltages to get faster charging.


Programmable Power Supply (PPS) Power Delivery (PD) Quick Charge (QC) Dash Charging WARP Charging VooC / Super VooC
Voltage & Current adjusted as per demand of Phone’s battery Goes up to 100W QC 3.0 allows 80% charge in 35 mins. Provides 63% charge in 30 mins. It goes 0 to 50% in 20 mins. Output ranges from 30W to 65W Improved Speed & Safety, Offers varying  outputs 25W & 50W outputs going upto 140W
Great Extending Battery Life Works in sync with PPS as well QC 3.0 is limited to Phones & Tablets.        (18W) Easy to perform high-intensity tasks Full charge in less than an hour. Low-voltage, fast-charging solution
Less Heat Generated. Goes upto a max of 45W Up to 70% faster than a normal USB charger QC 4.0 works on PD via Type-C (27W) Removes alarming heat generated quickly Heat gets dissipated in the adapter only Five-minute charge provides hundred minutes of gaming or four-hours of video watching
More Flexibility Ensures over-charging doesn’t take place QC 5.0 allows 50% in 5 mins. (100W) Designed for a mx output of 20W For effective cooling, OnePlus 6T McLaren Edition has 8 layer protection board Uses the highest level of multi-layered protection
Multiple Operating Modes

Laptops / Tablets / Phones/ Macbooks

iPad Pro/ iPhone 13 & 14
One of the most mature protocols with a long-standing prestige. Dash is a variant of Open VooC & used by OnePlus WARP is a variant of Open VooC & used by OnePlus Vivo’s Flash charge offers 33W Output
Most Commonly used by Samsung Adopted by Apple
