Yes, a USB-C hub can charge your laptop and output video at the same time, as long as the hub supports Power Delivery (PD) pass-through and your device is compatible.
- Hub has a dedicated USB-C PD pass-through port (up to 100W)
- Laptop supports USB-C Power Delivery or Thunderbolt 3/4
- PD charger is plugged into the hub’s PD port, not the data port
- Hub lacks a dedicated PD pass-through port
- Laptop does not support USB-C PD charging
- Hub firmware prioritizes charging over video or data output
How PD Pass-Through Works
A USB-C hub with PD pass-through has two separate USB-C ports: one connects to your laptop, and one accepts your wall charger. The hub routes power from your charger directly to the laptop while simultaneously handling video output and data — all over a single cable connection to the host device.
Most hubs deliver slightly less than the rated wattage to the laptop (typically 85–90W from a 100W charger) because the hub itself draws a small amount of power. For most laptops, this is enough to charge at full speed.
What Your Laptop Needs to Support
Your laptop’s USB-C port must support both video output and Power Delivery simultaneously. Ports that are data-only or charge-only will not handle both tasks at once. Check whether your USB-C port supports video output before assuming your setup will work.
Thunderbolt 3 and Thunderbolt 4 ports handle this reliably. Many modern USB 3.2 Gen 2 ports with DisplayPort Alt Mode also work, especially on laptops with Intel Ice Lake or newer chipsets.
Common Setups at a Glance
| Setup | Works? | Need | Note |
|---|---|---|---|
| Hub with PD port + Thunderbolt laptop | Yes | 100W PD charger | Most reliable option |
| Hub with PD port + USB-C PD laptop | Yes | PD charger + Alt Mode support | Check laptop spec sheet |
| Hub without PD port + any laptop | No | Separate charger required | Hub can’t pass power through |
| Hub with PD port + data-only USB-C laptop | No | N/A | Port won’t accept PD charging |
Troubleshooting: Video Works but Charging Doesn’t (or Vice Versa)
If your monitor connects fine but the laptop isn’t charging, make sure your charger is plugged into the hub’s PD port — not a standard USB-A or data USB-C port. If charging works but video doesn’t, the issue is likely Alt Mode support. See our guide on why USB-C to HDMI isn’t working for specific fixes.

What to Look for When Buying a Hub
- A labeled PD pass-through port (not just a USB-C data port)
- At least 85W or 100W PD rating for laptops
- HDMI 2.0 or DisplayPort output for 4K support
- Thunderbolt or USB4 certification if you need multi-display output
Bottom line: A USB-C hub can absolutely charge your laptop and drive a display at the same time — but only if the hub has a dedicated PD pass-through port and your laptop’s USB-C port supports both Power Delivery and video output. Check both before buying a hub.
