Quick Charge 4 Vs Power Delivery

How Much Do You Know About Fast Charging?

Smart gadgets are the most reliable tool in everyone's daily routine. From the moment you wake up and going to work. But how fast and reliable are your devices in helping you achieve your daily task efficiently? Smart technologies in this modern era is competing to how fast and reliable their products are. With the growing demand of technological advancement, big companies are including in their brands the phrase "fast charging". But how really fast are their technology compare to other brands?
Let's clear things out.

How Fast Charging Works?

If your battery can supply a charging current >9W (5v 1.8A), it is considered as fast charging device. 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 it delivers, the faster it charges.

WHAT IS QUICK CHARGE?

Quick charge allows smartphones, with a typical 5 volts 2 amps going beyond from most USB standards’ allowable. The latest quick charge product can charge batteries at a higher voltage, in which higher transfer rate is exceeding its normal condition through its common cable. When paired with compatible devices, a Quick Charge-enabled charger delivers more power, allowing the connected device to charge faster.

As one of the most widely used fast charging technologies, Quick Charge is already embedded in many of your favorite smartphones. If your smartphone is Quick Charge 3.0-compatible, you can charge up to 80% in just 35 minutes. 

With this emerging fast charging protocol, a device was developed to lead on the quick charging principle. A product solution that was made through research to help this fast and busy approach in life. It was called Nimble the world's first universal travel adapter, a technology that is equipped with three of the highest fast charging system PD, QC and USB C. It was made to charge both small and large devices with a very fast protocol of dual type C.

The following table is a presentation of the 4 versions of Quick Charge that are released:

IS IT SAFE?

As the battery charges up due to its quick charging system, it slowly goes down to less and less current consumption. That when the last 20% charging takes more time to full charge. This is one of the safety measures
that Quick Charge has developed. These systems is built with safety precautions it has over-voltage protection, over-current protection, over-temperature protection, connector protection and detection, and many more features. 

This is a well-designed technology with the sole purpose of keeping the customers safe.

To make Quick Charge more effective, both the device and the charger are compatible and accepting the system with the same version. Qualcomm’s Quick Charge has implemented a multiple levels of protection from battery system, cables and connectors as it is one of the contributor of most problematic issues while optimizing the use of smartphones. At great level of concern the system is still continuing its improvement.



WHAT IS POWER DELIVERY?

USB Power Delivery is a fast charging technology, supported by certain iOS / Apple and Android / Google devices, that delivers much higher levels of power than standard charging.
These systems is built with safety precautions it has over-voltage protection, over-current protection, over-temperature protection, connector protection and detection, and many more features. This is a well-designed technology with the sole purpose of keeping the customers safe.

Qualcomm’s Quick Charge has implemented a multiple levels of protection from battery system, cables and connectors as it is one of the contributor of most problematic issues while optimizing the use of smartphones. At great level of concern the system is still continuing its improvement.
USB-PD provides up to 100W of power, with up to 100W of power available, USB-PD can even charge larger devices, like tablets and laptops. All you need is the right wall charger and USB-C cable – and leave those heavy laptop power cables at home.

DO ALL DEVICES SUPPORT QUICK CHARGE?

Not all devices support this new technology, some smart devices are still catching up with this new and latest protocol.
However most new devices sold after 2017 have already adopted this new technology as they demand more power and as a consumer we want a faster charging time.
While others are catching up with the latest fast charging system. 

The Nimble comes with a powerful system embedded and equipped with QC and PD technology that is compatible with all newer devices that has the capability to use QC or PD. It is not just an adapter but it is a power plug converter and a charger, very useful when you forgot to bring with you your proprietary charger.
