Quick Charge 4 Vs Power Delivery and USB Type C
Smartphones nowadays are evolving. New model of 2018 might be an old model in 2019. Smart technologies in this modern era is competing to how fast and reliable their gadgets are. With this fast pace of technological advancement every small bits count. With the growing demand of smartphones, USB Implementors and other companies are dwelling on how to solve the long taking hours of charging smartphones and other USB type devices. Big companies are including in their brand the phrase “with fast charging”. But how fast are their technology compare to other brands?
How Fast Charging Works
But before we go into details let us know the basic concepts of how it works. Our smartphones has a battery. When it is charged it absorbed the power that flows through the cable. And when it discharged it produces electricity and this will be the cycle of the battery. Fast charging capacity depends on three factors the cable, charger and the phone itself.
Both phone and the charger must be compatible with the same charging voltages and currents. If your phone supports a charging power of 9V/2A, but your charger only has a 1A capacity then the process will take longer. This is the same as plugging a 2A charger or higher into an old phone that accepts 0.7A won’t make it charge any faster.
Learning Terminologies
In this area, we will be talking on volts, amperes and watts. Volts are a measure of voltage, amps are a measure of current, and watts are a measure of electrical power. A common analogy is a water pipe: Volts are equivalent to the water pressure in the pipe; the current is equivalent to the flow rate; and wattage is equivalent to the volume of the spout’s spray. Watts, then, are the product of volts and amps - volts (V) times amps (A) equals watts (W).
In a current state, fast charging increases the energy flow to the battery to fill up its storage quicker. From the 5 volts capacity USB specification only sends 0.5 amps (A) of current for just 2.5 watts (W). This is where fast charging technologies boost these figures. In other words, the higher the wattage of the battery delivers, the faster it charges.
Technical Details
If your battery can supply a charging current >9W (5v 1.8A), it is considered as fast charging device. The battery consists of two electrodes (one positive and one negative) and an electrolyte which catalyze reactions that convert compounds into new substances. As the battery charges, ions — atoms with too few or too many electrons — form in the electrodes, driving a flow of electrons to the battery’s negative outer terminal and supplying your phone with an electric charge. This is where smart charging takes place.
OnePlus 6T 4V/3.8A One Dash Charging produces 15W, Motorola 9V/1.67A TurboPower Charge up to 15W, Huawei’s 10V/4A Super Charge produces 40W and Samsung’s latest Adaptive Fast Charging produces 15W. Some other companies even boast charging technologies that can hit up to a maximum capacity of 100W. More power is the common goal of all fast charging services. Refer to the table below about the USB charging standards:

Up to 5V/0.5A (2.5W) that’s a typical USB 1.0 and 2.0 plug can deliver. That’s a regular charging rate of a typical phone, and it doesn’t have a lot of power. An iPhone charging at 2A over USB uses 5V x 2A = 10W it has adopted the Power Delivery system.
Quick Charge 4+
In the market, many fast charging protocols are competing with great brands including OnePlus Dash Charging, Motorola Turbo Charging, Adaptive Fast Charging from Samsung and OPPO VOOC etc., and Quick Charge from Qualcomm and USB Power Delivery from the USB-IF standards are the most common used protocols.
Quick charge is the only patented technology which was produced by a collaboration of big companies that allows charging of battery powered devices, especially mobile phones, with a typical 5 volts and 2 amps and beyond which most USB standards allow for.

To make Quick Charge more effective, both the device and the charger are compatible and accepting the system with the same version. If you worry how the power is implemented or worry about how recently battery fires that plagued Samsung’s Galaxy Note 7, then your worry is at ease with Quick Charge salient features that is more proactive. It has Over-voltage, Over-current and Over-temp protection with other great features like Cable quality and type detection like USB Type C, connector protection features, power regulation inside phone and many more. This system utilizes an enhancement of a consumers’ safety protection.

USB Type C and USB Power Delivery
USB-IF standards organization introduces USB Power Delivery in the market as a standard protocol to compete with the Quick Charge of Qualcomm. It requires a new connectors and cables for full USB 2.0 connector support to be implemented over any USB powered devices. USB Power Delivery together with the USB Type C has change its evolution of the fast charging protocol principles. With both protocols it powers up multiple USB type Devices at the advantage beyond its maximum capacity. Using USB Type C alone can support 5V at 3amps (15W), but together with USB Power Delivery it maximizes its ability up to 100W. You can use USB Type C for small gadgets but if you need more to power up large devices at a shorter time use both system protocols. If you are using Apple iPhone 8 and X, sadly it doesn’t provide the use of PD fast charging over USB Type-C to lightning adapter. Power Delivery support as high as 20V that can charge up to 100W max.
The Challenge Test
It is of vantage point on sales if you have this fast charging system protocol that enables every gadgets juice up from 1 to 5 hours of pumping charge down to 5 minutes charging. It helps people really have the capacity to do more on other stuffs with the help of these fast charging protocols. A company had tested some smartphone brands who leads the way in promoting fast charging competitions with a great results that is, fast charging on other brands is not that fast compared to some leading companies. Here are some of the results they conducted:

NOTE:
Shorter bars indicate a faster charge
In this result Android Phones are kicking Apple iPhone 7 Plus out of the race on their competition. In which Apple doesn’t offer a fast charging system. But it is your choice on what brand you love and friendly for your needs.
Quick Charge VS Power Delivery
To make it clear Power Delivery is more designed for larger devices like laptops and household appliances as it delivers much higher power output, while smartphones doesn’t need to have more than 18W of power charging, this is why Quick Charge was born to communicate with the smaller devices as a medium to a higher Power Delivery.
