QC 3.0 can change exact voltage and can be anywhere between 3.7 and 20v, the charging is variable and this increases the overall efficiency of the charge. Apple ได้นำเทคโนโลยี PD มาใส่ไว้ใน iPhone X,XR,XS,XSmax / iPhone 8,8+ / iPad Pro โดยชาร์จเร็วผ่านช่องชาร์จ USB-C to Lightning Voltcraft CQCP2400 operating instructions" (PDF) (User manual). Voltcraft. Output voltage/current 5 V/DC, max. 2400 mA or 9 V/DC, max. 1670 mA or 12 V/DC, max. 1250 mA

As you can see, PD 3.0 and QC 3.0 are similar, but remain distinct. They’re fundamentally different technologies. Which one is better? It really depends on your device. In theory, QC 3.0 is best for smartphones. By providing the exact voltage required, it allows you to maximize your battery’s performance. That said, it’s proprietary. Only certain Android phones currently support the technology. Unless you’re using one of these devices, you won’t be able to take advantage of QC charging. On the other hand, most modern smartphones support PD charging. These include all Apple phones starting with the iPhone 8.

Charging Speed: QC1.0 provided a charging speed that was up to 40% faster than conventional chargers. QC2.0 improved upon this, offering charging speeds that were up to 75% faster. However, QC3.0 raised the bar even further, allowing devices to charge up to four times faster than standard chargers and 38% faster than QC2.0. This significant improvement in charging speed makes QC3.0 the fastest charging technology among the three versions. Dynamic Voltage Adjustment: Once the voltage negotiation is complete, the QC3.0 adapter adjusts its output voltage to match the device’s requirements. QC3.0 supports multiple voltage levels, including 5V, 9V, and 12V, allowing for more efficient power delivery. This dynamic voltage adjustment ensures that the device receives the precise voltage it needs for optimal charging performance. A robust warranty covers the charger and will repair or replace devices that are damaged while properly PD 3.0 is a fast charging technology that was developed by the USB Implementers Forum. Because it’s an official part of USB technology, it can be supported by any manufacturer. No manufacturer has to pay extra licensing fees to incorporate PD 3.0 technology into their product. All they need to do is built the circuitry and the battery to the PD 3.0 specifications. I incremented and decremented until the voltage stopped changing. My particular device accepted decrement pulses until it should be (nominally) 3.6V, though the voltmeter continued to display 4.27V. I suspect that's the actual output voltage of the LiPo cells inside the device,...

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. It is capable of delivering up to 100W – even though smartphones don’t need up to that to fast charge. It is useful for other devices though, including laptops with USB-C port. Safety Features: QC3.0 adapters integrate various safety features to protect both the device and the charger from potential risks. These safety mechanisms include overvoltage protection, which prevents excessive voltage levels that could damage the device, and overcurrent protection, which safeguards against power surges. Additionally, temperature monitoring ensures that the charging process remains within safe temperature limits, preventing overheating issues.

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. Fast Charging Circuitry: QC3.0 adapters feature specialized circuitry that is designed to handle higher power output and fast charging speeds. This circuitry ensures that the power generated by the adapter is transmitted efficiently and safely to the device’s battery. The fast charging circuitry helps minimize power loss and heat generation, resulting in faster and more efficient charging. It works using what Qualcomm is calling Intelligent Negotiation for Optimum Voltage (INOV). This is a new computational algorithm that allows the device being charged to determine the power level it needs at any point in time, which means it's always working with the most efficient and optimized power transfer rate. Support for a wider range of voltage options — 200mV increments from 3.6V to 20V — means your phone can dynamically target one of dozens of charging levels. With these features, QC3.0 adapters offer a superior charging experience by providing faster speeds, wider compatibility, and enhanced safety. Whether you’re a busy professional, a frequent traveler, or simply someone who values convenience and efficiency, a QC3.0 adapter is an essential accessory to have for your compatible devices. Benefits of Using QC3.0 AdapterNotebook บางรุ่นมีช่องชาร์จไฟบ้านเข้าแบบ USB-C แต่ก็ไม่รองรับเทคโนโลยี PD หรือ โดนล็อคไม่ให้สามารถชาร์จเข้าด้วย Charger อื่นได้) In our photo of the most common connections, we mistakenly used a USB 3.0 Type-B cable, instead of a USB 2.0 Type-B cable as planned. We’ve updated the caption to refer to the 3.0 connector, and we apologize for any confusion. The advantage of 3.0 is that it can provide optimal voltage at the precise need of the battery, so during charging you are always at the fastest charging voltage. Efficient Power Transfer: QC3.0 adapters are designed to minimize power loss during the charging process. This results in more efficient power transfer from the adapter to the device, further enhancing the charging speeds and reducing wasted energy.

Unlike other third-party manufacturers, Belkin has 100% control, from concept to production. This allows

Avoid Extreme Temperatures: High temperatures can have a negative impact on the charging efficiency and overall performance of both the device and the adapter. Avoid exposing your device and QC3.0 adapter to extreme heat or cold, as it can affect the charging process and potentially cause damage to the components. Store and use the adapter and device in a cool and well-ventilated area. From left to right, the most common USB connections (and their uses): Mini-USB (older cameras and hard drives), USB 3.0 Type-B (desktop hard drives), USB-C (future devices), Micro-USB (all manner of current mobile devices), USB-A (source port on computers and chargers).
