As technology advances, our devices are becoming increasingly dependent on USB-C hubs to expand their connectivity options. However, with the rise of USB-C hubs, a common concern has emerged: how much power do these hubs draw? In this article, we will delve into the world of USB-C hubs and explore the factors that affect their power draw.
Understanding USB-C Hubs and Power Delivery
Before we dive into the power draw of USB-C hubs, it’s essential to understand how they work. USB-C hubs are designed to expand the connectivity options of devices with USB-C ports. They can provide additional USB ports, HDMI ports, Ethernet ports, and even power delivery. The power delivery feature allows USB-C hubs to charge devices, making them a convenient accessory for travelers and professionals.
The power delivery feature of USB-C hubs is based on the USB Power Delivery (PD) specification. This specification allows for the delivery of up to 100W of power over a USB-C connection. However, not all USB-C hubs support 100W power delivery. The power delivery capacity of a USB-C hub depends on the type of controller chip used and the design of the hub.
Factors Affecting Power Draw
Several factors affect the power draw of a USB-C hub. These factors include:
- Number of ports: The more ports a USB-C hub has, the higher its power draw. This is because each port requires power to operate.
- Type of ports: The type of ports on a USB-C hub also affects its power draw. For example, HDMI ports require more power than USB ports.
- Power delivery capacity: The power delivery capacity of a USB-C hub affects its power draw. Hubs with higher power delivery capacities require more power to operate.
- Controller chip: The type of controller chip used in a USB-C hub affects its power draw. Some controller chips are more power-efficient than others.
Power Draw of Different USB-C Hubs
The power draw of USB-C hubs varies widely depending on the factors mentioned above. Here are some examples of USB-C hubs and their power draw:
| USB-C Hub | Number of Ports | Power Delivery Capacity | Power Draw |
| — | — | — | — |
| Anker USB-C Hub | 4 USB ports, 1 HDMI port | 60W | 5V, 1A |
| Aukey USB-C Hub | 6 USB ports, 2 HDMI ports | 100W | 5V, 2A |
| CalDigit USB-C Hub | 4 USB ports, 1 Ethernet port | 85W | 5V, 1.5A |
As you can see, the power draw of USB-C hubs varies widely depending on the number of ports, power delivery capacity, and controller chip used.
Measuring Power Draw
Measuring the power draw of a USB-C hub is a relatively simple process. You can use a USB power meter to measure the power draw of a USB-C hub. A USB power meter is a device that connects between a USB device and a USB port and measures the power draw of the device.
To measure the power draw of a USB-C hub, follow these steps:
- Connect the USB power meter to the USB-C hub.
- Connect the USB-C hub to a power source.
- Turn on the USB-C hub.
- Measure the power draw of the USB-C hub using the USB power meter.
Interpreting Power Draw Measurements
When interpreting power draw measurements, it’s essential to understand the units used. Power draw is typically measured in watts (W) or volts (V) and amps (A). For example, a power draw of 5V, 1A means that the device is drawing 5 watts of power.
When interpreting power draw measurements, consider the following:
- Idle power draw: The power draw of a device when it’s not in use.
- Active power draw: The power draw of a device when it’s in use.
- Peak power draw: The maximum power draw of a device.
Power Draw Measurements of Different USB-C Hubs
Here are some power draw measurements of different USB-C hubs:
| USB-C Hub | Idle Power Draw | Active Power Draw | Peak Power Draw |
| — | — | — | — |
| Anker USB-C Hub | 0.5W | 5W | 10W |
| Aukey USB-C Hub | 1W | 10W | 20W |
| CalDigit USB-C Hub | 0.5W | 5W | 15W |
As you can see, the power draw of USB-C hubs varies widely depending on the device and its usage.
Conclusion
In conclusion, the power draw of a USB-C hub depends on several factors, including the number of ports, power delivery capacity, and controller chip used. Measuring the power draw of a USB-C hub is a relatively simple process using a USB power meter. When interpreting power draw measurements, consider the idle power draw, active power draw, and peak power draw.

What is a USB-C hub and how does it work?
A USB-C hub is a device that expands the capabilities of a single USB-C port on a computer or laptop, allowing users to connect multiple devices and peripherals at the same time. It works by using the USB-C port to connect to the host device, and then providing multiple ports for connecting other devices such as flash drives, keyboards, mice, and monitors.
The hub uses a chip to manage the data and power flow between the connected devices and the host device. This chip, known as a controller, ensures that the data is transmitted correctly and that the power is distributed safely and efficiently. Some USB-C hubs also have additional features such as built-in cables, wireless charging, and power delivery.
What is power draw and why is it important for USB-C hubs?
Power draw refers to the amount of power that a device consumes from the host device or an external power source. In the case of USB-C hubs, power draw is important because it determines how many devices can be connected and used at the same time. If the power draw is too high, it can cause the hub to overheat, slow down, or even shut down.
A good USB-C hub should be able to manage power draw efficiently, ensuring that each connected device receives the power it needs without overloading the hub. This is especially important for devices that require a lot of power, such as external hard drives and monitors. Look for a hub that has a high power delivery rating and multiple power management features to ensure safe and efficient operation.
How do I choose the right USB-C hub for my needs?
Choosing the right USB-C hub depends on several factors, including the type and number of devices you want to connect, the power requirements of those devices, and the features you need. Consider the number and type of ports you need, such as USB-A, USB-C, HDMI, and DisplayPort. Also, think about the power delivery rating and whether you need features like wireless charging or Ethernet connectivity.
It’s also important to consider the compatibility of the hub with your device. Check the specifications of your device to ensure that it supports USB-C hubs and that the hub you choose is compatible with your device’s operating system. Additionally, read reviews and check the manufacturer’s reputation to ensure that you’re getting a high-quality hub that will meet your needs.
