USB-C hubs are essential for modern laptops, offering HDMI, Ethernet, and multiple USB ports in a single device. However, a very common issue users face is:
❗ The USB-C hub is not charging the laptop
If you're searching for:
- USB-C hub not charging laptop
- USB-C hub power delivery not working
This guide will help you diagnose and fix the problem quickly.
1. Not All USB-C Hubs Support Charging
There are three types of USB-C hubs:
Basic Hub (No Charging)
- Data + HDMI + USB only
- No power delivery support
PD Pass-Through Hub
- Has a USB-C PD input port
- Requires external charger to function
Full Power Delivery Hub
- Supports 60W / 85W / 100W charging
- Can charge laptop while using other ports
👉 Many cheap hubs only support data, not charging.
2. No PD Charger Connected
USB-C hubs do NOT generate power.
👉 You must plug in a USB-C PD charger into the hub.
Correct setup:
Wall Charger → USB-C Hub PD Port → Laptop
3. Charger Wattage Is Too Low
If your laptop requires:
- 65W but you're using a 20W charger
👉 The laptop will NOT charge properly.
Recommended:
- MacBook Air: 30W–65W
- MacBook Pro / Windows laptops: 65W–100W
4. Hub Does Not Support Power Delivery
Some hubs advertise:
- HDMI
- USB ports
- Ethernet
But do NOT include:
- PD chip
- Power passthrough circuit
👉 Result: no charging at all
5. USB-C Port Does Not Support Input Charging
Not all laptops support charging via USB-C hub.
Some ports only support:
- Data transfer
- Display output (DP Alt Mode)
👉 Check your laptop specifications carefully.
6. Cable Does Not Support PD Charging
A low-quality USB-C cable may:
- Transfer data only
- Limit power to 15W–30W
👉 Always use:
- USB-C 3.1 / 3.2 cable
- 100W certified PD cable
7. Too Many Devices Connected
If you're using:
- External SSD
- HDMI display
- Ethernet
- USB accessories
👉 Power distribution may fail, causing no charging.

✔ Use a PD-enabled charger (65W–100W)
✔ Connect charger to hub PD input

How to Choose a USB-C Hub That Supports Charging
Look for:
✔ USB-C Power Delivery (PD) 85W–100W

Common Mistakes
❌ Thinking all USB-C hubs charge laptops

👉 Cable limitations
Once these are fixed, most charging issues disappear instantly.
