How to Check If a USB-C Port on Your Hub Supports Power Delivery？
USB Hubs
A USB hub is a useful tool that expands a single port into several ports available to connect more devices to a host system. All devices connected through a USB hub share the bandwidth.
USB Hub Ports
The best advantage of the USB-C hub is its versatility. You can use multiple ports at the same time to extend the connectivity. USB-C hubs usually include a range of ports, each with a unique purpose. You’ll often see USB-A, USB-C, HDMI, DP, RJ45, Ethernet, and other ports.
USB-A ports, often regarded as the big boss of USB connectors, continue to be prevalent in many devices, even with the rise of USB-C interfaces. HDMI and DisplayPort enable the output of high-definition video and audio to external screens. These ports are commonly used to connect laptops or tablets to TVs or monitors, facilitating multi-screen presentations or larger displays. Ethernet ports still provide a reliable and fast internet connection, sometimes surpassing Wi-Fi in specific situations.
A port is only as good as the protocol that powers it. USB 3.1 is an upgrade from the old USB 3.0. Thunderbolt 3 is like USB 3.1 on steroids, with data transfer speeds of up to 40Gbps and the ability to transfer video and power, which is a protocol for the most demanding tasks. These protocols affect device interaction and performance, especially when running high-bandwidth applications like video editing software or playing games.
USB Power Delivery
The USB Promoters Group announced the finalization of the USB PD specification in 2012 and launched revision 3.1 of the specification in 2021. As a logical progression from the current European and Chinese mobile phone charging standards, PD will allow universal charging of laptops, tablets, USB-powered drives, and other similarly higher-power consumer electronics. Coexisting with the earlier USB Battery Charging specification, the standard aims to expedite the charging process.
It can offer up to 100 watts of electricity via a single USB connection, which is sufficient to charge larger devices like laptops as well as tablets. Because of its versatility, USB PD ensures safe and effective charging by dynamically adjusting the power flow to the needs of the attached device. Additionally, this protocol can transfer and receive power because it offers bi-directional charging.
The USB PD standard features an adjustable voltage supply mode that engineers can customize. This allows a single adapter to charge multiple devices at optimal levels, even if they have different voltage requirements. It is able to be achieved by combining USB-C with the USB Power Delivery power protocol.

USB-C & USB PD
USB-C and USB-PD are not the same. The physical connector is described in the USB-C standard. An adapter does not always have USB PD functionality just because it has the shape.
Choosing USB type-C connectors for a design does not require an engineer to follow USB PD. However, USB type-C connectors have a symmetrical, self-aligning connector that makes it much easier to insert correctly, and they can transport both power and data over the same cable.
How to Find USB-C Ports That Support PD
Some USB-C ports may feature a little lightning or PD symbol next to them to indicate support for Power Delivery.
Examine your hub’s specifications or product documentation carefully. If the USB-C port supports Power Delivery, it ought to be indicated.
Check the manufacturer’s website for detailed specifications and support information regarding your specific model.
Attach a device that is compatible with Power Delivery and check if it charges. If it does, the port does support PD. Meanwhile, if you have access to a USB power meter, you can measure the voltage and current being supplied through the port, as Power Delivery usually negotiates higher voltage levels.
Conclusion
Power Delivery has revolutionized the way to juice and utilize our smart devices. This protocol has led many mobile device brands to adopt a unified design standard for the USB-C platform. It’s no exaggeration to say that Power Delivery has significantly shaped the way we interact with mobile devices in this decade.
Verifying that the USB-C port on your hub supports PD is critical to maximizing the charging efficiency of your devices. USB hubs are really handy for workstations because they let you connect multiple devices through just one port. At the same time, not every hub supports Power Delivery, the ones that do can make your charging setup a lot easier by powering several devices at the same time.
To determine which ports support Power Delivery, check for specific symbols, refer to the product documentation, or test with a device that is known to be compatible with PD. Familiarizing yourself with the distinctions between USB-C and USB PD will help you select the right hub for your requirements. By harnessing the advantages of USB-C PD, users can minimize clutter, streamline their workspace, and ensure their devices are charged efficiently.
