Today, when you are shopping for a power bank in a store or on an online shop, you will be properly confused by those marks about qucik charge. Some power banks support PD fast charge, while others support QC 3.0 fast charge. So how to choose a suitable power bank for your smart phones?
First let’s see what is PD fast Charge and QC 3.0 fast charge：
What is PD fast charge ?
PD is short for “power delivery”. The technology is capable of delivering up to 100 watts of power, far more than any smartphone requires. However, this high wattage has some significant advantages. For instance, it can be used to power laptops. Apple’s new MacBooks all use it, and can even be used while they’re charging. This means you’re getting much better performance than you’d expect from a standard USB cable.
PD (Power Delivery) is a fast charging technology developed by the USB-IF Association. It adopts the latest USB-C interface, and there is no longer a distinction between the front and back of USB-C. It can support a variety of devices and also support to charge iPhone/ iPad devices.
Except for the iPhone (Lightening port), all devices that support PD fast charging must be charged through a USB-C port, so if your new device still use a traditional USB-A charging port or charger, it is high chance that it may not support fast charging.
What is QC 3.0 fast charge ?
Quick Charge 3.0 is a technology developed by Qualcomm after years of researching how to safely speed up the mobile device charging process. Prior to this technology’s release, charging mobile devices was constrained by slow, less-efficient charging mechanisms. Quick Charge 3.0 was designed to efficiently allow for shorter charging times of larger batteries.
Qualcomm Quick Charge 3.0 is designed to be able to charge the average smartphone’s battery to 50% in half an hour. Drawing 36 watts of power, it charges twice as fast as the original Quick Charge 1.0 ever could.
What kind of power bank should I choose for my smart phones or othe devices? PD or QC 3.0 ?
Both PD 3.0 and QC 3.0 will charge your battery faster than traditional USB. At the same time, there are important differences between the two. Depending on your phone, one or the other can be a significantly better choice.
For Android devices that support both standards, QC 3.0 is generally faster. PD charging won’t always have an exact wattage or voltage that matches your device’s needs. If it doesn’t, it will default to the next lowest power level. With QC 3.0’s technology, you’ll always get the maximum voltage.
On the other hand, Apple and Google Pixel phones are a bit different. Both of them use PD 3.0 only. As with Android devices, though, your performance will depend on your device. For example, older Apple devices like the iPhone 7 don’t support any kind of fast charging. But with the iPhone 8 and newer, you get full PD compatibility. Be aware that you won’t get any benefit whatsoever from a QC 3.0 charger. Apple phones simply aren’t compatible with the technology.
More and more power banks or wall chargers support both PD and QC fast charging technology
Fotunately, today more and more power banks adopts both PD and QC fast charging technology. If you are not sure about which fast charging technology your smart phones support, you can simply choose a power bank which both support both of them.
You may also have several smart phones and other devices . Some of them support QC3.0 , while others support PD3.0. With a transparent Mecha power bank, it can charge all of your deives at a fastest speed.
