Power Delivery PD, Quick Charge QC and wireless charging: fast charging standard guide for beginners.
PD, QC and wireless charging are the latest fast charging standard. New tech products constantly refer to these terms. So what are they? Do your phone and charger support these fast charging standards?
Fast charging standard PD (Power Delivery)
PD, also known as USB Power Delivery charging, is a fast charging standard that is in vogue. So, what is PD charging standard? PD charging is a specification capable of handling high power and fast charge handheld devices via a USB-connection. The PD system creates an electrical current exchange between two devices to jointly determine a common electrical level. Due to that, there is increased capacity and reduced charging time.
The PD fast charging standard goes far beyond previous charging standards, it starts at 5V and can go up to 20V. When you use a standard USB-C cable, the PD is capable of handling up to 60W. Moreover, it can handle up to 100W when using the specified EMCA cable.
Another noteworthy point regarding Power Delivery fast charging is that it allows current to flow in both directions, with no direction based on the circuit or connection. For example, if you connect two phones that support Power Delivery with a USB-C charging cable, one phone can charge the other and vice versa.
Fast charging standard QC
QC shorts for Quick Charge is Qualcomm’s fast charging standard, developed and used on some popular smartphones and tablets. Like USB PD, QC 3.0 and QC 4.0 are variable voltage technologies and are intelligently calibrated for your device to have optimal and safe charging speeds. However, unlike USB PD, Quick Charge 3.0 and 4.0 have some additional features to reduce heat generation while charging.
While QC 2.0 and QC 3.0 still use the traditional USB A connector, QC 4.0 is Qualcomm’s first fast charging product that is compatible with the USB C connector. QC 4.0 allows the device to charge from 0% to 50% only in within 15 minutes. However, only electronic devices using Qualcomm’s Snapdragon processor have QC.
With wireless charging technology, you no longer need to plug a cable into a smartphone to charge it. Just placing a phone with built-in wireless charging on a charging pad or a tabletop with this feature is enough to start charging. Current phones like iPhone 11, iPhone X, iPhone 8, Samsung Galaxy S8, S9, and S10 and many new smartphones all support wireless charging.
Some wireless chargers are faster than others and are able to charge a smartphone with a large battery capacity in just two hours. Wireless charging is often rated by wattage, most commonly 5W and 10W chargers; or by the output intensity, with a 1A wireless charger at 5V equivalent to the standard USB 1A cable charger as bundled with iPhone 7.
Currently, the wireless charging industry is growing, and the charging standard is extremely important. Most smartphones support both Power Qi and PMA or AirFuel Alliance standards. This means the new smartphones will work on most chargers available. If you’re still wondering about the charging standard, just buy one with Qi. Qi is rapidly becoming the most popular wireless charging standard and is being used by Apple for the new iPhone X and iPhone 11.
