If it wants to offer downstream USB-C ports, or if it wants to accept USB-PD to enable charging the host while in use, then it generally does accept an external power supply. Usually this is optional.
Do USB-C hubs provide power?
Fortunately there are some USB-C hubs on the market that can support Power Delivery (PD) pass-through charging. Pass-through charging is where you connect the hub to your laptop, and then connect your laptop’s USB-C charger to the hub’s PD input port. Some hubs with this feature can even support up to 100W charging.
Should a USB-C hub be powered?
The suitability of each hub depends on your needs and how you want to use the USB C hub. You would use a powered hub if you need to run devices that use high voltages of power such as printers, external hard drives, and scanners. A powered hub would also be ideal if you want to use several devices at once.
How much power does a USB-C hub use?
When there’s no USB-C power adapter plugged into its pass-through USB-C port, it can draw up 15W from the host Mac, consumes 1.5W for itself, and divvies up the rest between the two Type-A ports, the SD card slot, and the HDMI port.
Is it worth getting a powered USB hub?
Because a powered hub uses mains power, it can give every device connected to it the maximum voltage that USB allows. So, not only can it run more devices than an unpowered hub, it can do so at full power, without any drops in performance.

Can I power my laptop through a USB-C hub?
Will any port work with any charger? USB-C is a universal charging standard. That means that, technically, it doesn’t matter what USB-C charger you use — it should be able to power up a laptop with a USB-C charging port and power bank.
Do USB-C hubs drain battery?
Yep. If its a USB powered monitor and the hub is also USB powered then the battery will get drained quickly.
Are expensive USB-C hubs worth it?
Expensive hubs can handle more and handle it much faster. The most advanced USB-C docking stations have newer ports with technologies, like Thunderbolt 3, that support faster charging and faster data transfer. The more expensive the laptop accessory, the more likely it is to support a high-resolution monitor, too.
Do all USB-C hubs get hot?
If you find your USB-C hub gets a little warm when you’re using the devices connected to it, it’s not something to be too concerned about. The hub will get warm when it’s transferring data or charging devices connected to it, particularly if you have several things connected at once.
Do USB-C hubs affect performance?
In general a type of USB power (PC port or active hub) does not affect hard drive performance.
What should you not plug into a USB hub?
Hard drives are really the only thing that can be problematic with a hub.
Does a USB hub reduce power?
When a power adapter is not used on a hub that comes with a power adapter, power is drawn from the USB port on the computer and then divided between the ports on the hub. This reduces the power delivery to individual ports and high-powered USB peripherals, such as external hard drives, may not start.
Can a USB hub draw too much power?
Devices can pull as much power as they want, but there are consequences. Devices are supposed to follow certain rules, like pulling no more than 100mA unless they configure up to a higher amperage (500mA for USB 2.0 and 900mA for USB 3.0). This is to avoid voltage drops which might knock other devices off the bus.
What is the difference between a USB hub and powered USB hub?
Additionally, USB hubs can be useful with devices like laptops that can’t physically add more USB ports. The difference between powered and non-powered USB hubs is that the former draws its power from an electrical outlet while the latter draws its power from the computer connection.
Why are there no USB-C hubs?
According to this thread In the Super User Forum there are no USB-C hubs with five, ten or more C ports because the chips required for this are missing. The technology for the junction boxes is therefore not yet available.
Do USB-C hubs support charging?
Power pass-through: All the hubs we considered also have a USB-C port that allows you to plug in your charger without taking up a second port on the computer itself (if it even has a second port).
Do all USB-C ports support power delivery?
Just because it includes a USB-C port, does not necessarily mean that port supports Power Delivery and will output 60W on that one port alone. Instead, keep an eye out for a charging solution that includes a USB-C port with a specific Power Delivery rating of up to 60W.
