Yes! This is another great benefit of USB-C. It was described earlier that the goal of USB-IF is to eliminate a large number of connectors and ports used for different purposes. This also applies to charging cables. Previously, only small devices like mobile phones or headsets could be charged via a USB cable (you may have a drawer of micro-USB cable from every device you own). This is because the maximum capacity supported by the USB charging protocol is 5V. There are many proprietary non-usb-supported protocols available, but it creates a chaotic landscape of charging standards and accessories. USB-C power transmission expands the charging specification to 20V access, up to 5A, or up to 100W. This huge growth has allowed large devices like laptops to be charged with USB-C. For example, a 15-inch MacBook Pro sells for 87 watts. For charging over 60W, you need to make sure you are using an electronically marked USB-C power cable.
USB-C can charge larger devices such as laptops, but is USB-C charging generally faster? The answer is usually yes, but it depends on how it is implemented. High-end smartphones such as the iPhone and Google Pixel all use USB-PD support for higher voltages, so their charging speed is much faster than older phones. The downside is that you’ll have to shell out more money for the high voltage USB-C chargers and in the case of the iPhone, a USB-C to lightning cable. On the other hand, most USB-C cables should support charging up to 60W, just make sure they’re from a reliable brand. Better yet, make sure they’re from a USB-IF member brand such as Cable Matters.
Although you may not notice the last feature, the latest standard Power Delivery 3.0 supports the Programmable Power Supply (PPS) protocol. The PPS mode basically allows different amounts of power to be transmitted to a device instead of a constant power flow. The lithium-ion battery in your phone will thank you for this, because this strategy allows it to charge at the optimal speed and helps extend the life of the battery.
