Do you ever hear of quick charging, fast charging, rapid charging, USB power delivery charging and, Qualcomm Quick Charging 2.0/3.0/4.0? Never hear any of them even once before this post? I’m here to increase your knowledge. Firstly, I clear that Qualcomm technology made them and all are the same things. The company designed them to charge your battery.
As we know it’s 2021 and the smartphone industry is buzzing with fast charging standards like adaptive fast charging, USB power delivery charge, Qualcomm Quick Charge, OnePlus Warp Charge, and so on. Apart from the Qualcomm Quick Charge and USB power delivery charge, the rest are made for limited brands.
And the Qualcomm Quick Charge plus USB power delivery are universal brands and are available for several smartphone brands (because these two brands are integrated with a number of products) including tablets, be it the iPhone 11 Pro Max or Redmi Note 9 Pro. If we observe the both PD or QC they both look the same. But they have clear differences. And according to some people, PD and QC are the two versions of the same products. Let me try and clear all confusion regarding the two. Here is the best USB outlet power strip. Or you can mail us at lisa@jeostorm.com.
What is Qualcomm Quick Charge 2.0 and 3.0
Firstly, let’s talk about what the QC charge is. Qualcomm technology made Quick charging basically for fast charging. And Qualcomm was released in 2013 firstly. The Qualcomm actually supplied 10 wattages in total.
And Qualcomm Quick Charge 4 + is the latest one. So the question arises at what wattage does the QC compatible with the power bank? Quick Charge 2.0 allows different voltage modes including 5V/2A, 9V/2A, and12V/1.67A for the old and starter standards.
Similarly, the Quick Charge 3.0 encourages charging between 3.6V to 22V with 200mV dynamic voltage increments.
As compared to the previous, the newer QC 4 is 20% faster and 30% more efficient. As it is newer tech, so it is compatible with USB Type-C and USB Power Delivery (USB PD). Moreover, QC 4.0 is famous for 5/5, that’s means 5 hours of battery in just 5 minutes of charging. Cool isn’t it?
Note: Qualcomm Quick Charge only works with that brands that have Qualcomm chipsets under their hood.
What is Power Delivery Charge
USB PD (power delivery) is known as becoming a universal charger that can be integrated with several devices with the same charger. It has a standard USB connection. And more interestingly, for its better working, you don’t need to have a special chip. So this gives it a universal approach for iPhone and Android users.
The universal approach also means compatibility to share cables and charging adapters. The company not limited USB PD to smartphones but it has access to laptops, tablets, and iPad Pro. Nice to know, right? The aim of a universal charger is to reduce the charger clutter in every home or to facilitate the smartphone industry (no need to bundle a charger with all gadgets). So the question arises how it works?
The working style of the USB PD is very simple. When you plug your device into the USB PD charger, it tells you how much charging your devices need. And the wattage starts from 7.5W up to 1000W in the power delivery charger. The voltage power is varied, it starts from 5V or can go up to 20V. The company split power into four categories — 7.5W, >15W, >27W, and >45W.
You can achieve a voltage of 100W by combining 20V + 5A. And the story does not end there. It also allows reverse charging. It’s mean if you hook two compatible devices by USB-C cable the two can charge each other but at a different speed. Pretty cool! PD 3.0 is the newer one.
It is the common question that which is fast. So it depends upon your devices. If you are using lower quality phones, then they don’t have PD or QC. It is different in the case of androids that supported power delivery and Qualcomm charge. The devices supported both are faster and receive charging quickly.
On the other hand, Google and Apple phones just use PD 3.0 only. But it is not the same case with iPhone 7 or previous models, because they don’t support PD. The company make the newer models. that are integrated with PD 3.0, fast charging. Also, Apple phones are not compatible with QC 3.0 chargers. Apple phones are not shipping with a PD 3.0 charger, rather if you want PD speed you should buy the PD Charing block separately. The company shipped MacBooks with PD-cable chargers.
Which devices qualify
So which devices are compatible. With Qualcomm Quick Charge or power delivery charge, there are a number of phones and power banks. I’m going to list a few of them.
Apple iPhone 11 (Power Delivery)
The Apple iPhone 11 Pro brings an exciting array of features to the table. It has a stellar display and well, streaming HDR content is a delightful affair.
RAVPower 61W PD 3.0 (Power Delivery)
The RAVPower 61W PD 3.0 is a compatible device that is designed to charge anything from smartphones and USB-C laptops like MacBook Pro and Chromebooks. It’s small and compact doesn’t eat up much real estate.
JEOSTORM USB C Power Strip (Power Delivery)
The JEOSTORM USB C power strip Charger brings the power of PD to the phone. It bundles a USB-C port and three USB-A ports.
Final Verdict
To wrap the discussion up, we mentioned some of the differences between the quick charger and the PD charger. The Quick Charge is limited only to a few devices like the Xiaomi Mi 8, Xiaomi Mi MIX 3, and Black Shark 2. While the PD charger is a universal charger.
It is not limited to some specific devices, but it has its strong feet in the smartphone industry. So you need a dedicated charger to get the most power of it. PD is the future of the smartphone industry because it can engage more than one devices, less-e-waste, and as fast as flesh.
