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.
Proprietary technologies are pushing the boundaries even further, with Oppo teasing 240W capabilities and Xiaomi already offering 120W charging. That said, there are diminishing returns in terms of power consumption versus charge time anyway. Around 40W is plenty to charge a smartphone super fast. Consumer convenience and the ecological argument
Created in the mid-1990s, USBs (Universal Serial Bus) are the general go-to standard for connecting devices, charging, and data communication. And with such a long running standard, it has been updated over the years with 2.0, 3.0, Micro-USB, and Type C versions (just to name a few). While USB was once used as mainly for data communication with limited charging capabilities, many devices now use a USB primarily for charging. This includes many mobile phones, computers, and plenty of other devices. However, this can lead to some issues as certain devices or cables are not compatible with other types of ports. Compounding that is the fact that there are speed differences between different types of USB. Case in point, Type C is faster than USB 3.0 which in turn is faster than 2.0. This leads to a lot of e-waste as people are constantly buying new cables or devices when USB technology advances further. What is USB Power Delivery? However, this issue of compatibility is about to be a thing of the past with the introduction of the USB Power Delivery Specification. USB Power Delivery (or PD, for short) is a single charging standard that can be used all across USB devices. Normally, each device charged by USB will have their own separate adapter, but not anymore. One universal USB PD will be able to power a wide variety of different devices.
Three Great Features of USB Power Delivery? So now that you know a bit about what the USB Power Delivery standard is, what are some of the big features that make it worthwhile? The biggest draw is that USB Power Delivery has increased standard power levels to up to 100W. This means your device will be able to charge much faster than before. Also, this will work for most devices and will be great for Nintendo Switch users, as there have been many complaints about it charging slow.
Another great feature of USB PD is the fact that the power direction is no longer fixed. In the past, if you plugged your phone into the computer, it would charge your phone. But with Power Delivery, the phone you plug in could be responsible for powering your hard drive. Power Delivery will also ensure devices are not overcharged and will only provide the necessary amount of juice needed. While most smart phones won’t be able to take advantage of the added power, many other devices and computers will be able to.
