What is the difference between PD3.0 and QC3.0?

This page clearly explains the differences between QC (Quick Charge) 3.0 and PD3.0 in AC/DC Power Adapter.

PD3.0 vs QC3.0

You have probably seen labels such as PD3.0 and QC3.0 at electronics retail stores. Both are standards for fast charging smartphones and tablets, but you may wonder what the difference between them is.

You may also often notice that some Products support PD3.0, while others indicate support only for QC3.0.

Which standard offers faster charging speed?

The charging speed depends on the device, so it is very difficult to determine which standard is faster. The charging speed of smartphones and other devices depends on the capabilities of the phone being charged.

What is the difference between PD3.0 and QC3.0 for Android smartphones?

For Android devices that support both PD3.0 and QC3.0, QC 3.0 is generally said to be faster. The reason for this is INOV technology. With the PD charging standard, there is not always an exact wattage or voltage that matches the needs of the device in use. If not, the charging defaults to the minimum required power level. With QC 3.0's INOV technology, this does not happen, and the maximum voltage is always delivered.

By the way, the iPhone is not related to QC

Apple smartphones are somewhat different from Android devices (including Google Pixel). These smartphones support only PD 3.0 and use a technology separate from QC.

Summary

From a charging perspective, the advantages of PD3.0 and QC3.0 can be summarized as follows: PD3.0 is an ideal standard for laptops and other peripherals that require higher wattage. It supports up to 100W and can optimally charge devices even while they are in use (of course, support up to 100W depends on the device being charged).

QC3.0 is particularly suitable for charging Android smartphones. Because it can supply the precise voltage required by the device, it maximizes battery performance.

UNIFIVE is currently developing a foldable USB AC/DC Power Adapter equipped with both PD and QC ports. With this, optimal power delivery will be possible for a wide range of devices.
