💻 Why Does Your Laptop Overheat or Freeze?
The Hidden Danger: Cheap USB-C Hubs Without a Controller Chip!
Many low-cost USB-C hubs on the market may look convenient, but most lack a dedicated chip to regulate power and voltage – a serious risk for your laptop.
⚠️ What Happens When You Use a No-Name Hub?
- No voltage control → unregulated power enters the device
- Motherboard may overheat
- System freezes, crashes, or permanent port damage may occur
Devices most at risk include:
- Dell (XPS,…)
- Apple MacBooks
- ASUS ZenBooks
- Lenovo
and other thin-and-light ultrabooks.
