Magnetic USB Adapter for ThinkPad

This adapter converts a standard USB port into a magnetic DC round connector for compatible ThinkPad, ThinkBook and Xiaoxin laptops. It is intended for users who want a quick-release charging connection that reduces wear on the device's built-in port. The 360 degree rotation allows the cable to align from any angle without forcing the plug.

Check Connector Compatibility Before Ordering

Verify that your laptop uses a DC round head charging input that matches the adapter's generous square mouth interface. The unit relies on an 8 pin magnetic contact layout, so it will not work with USB-C Power Delivery or barrel connectors of a different pin count or diameter. Ensure your power supply provides the correct voltage and current for your specific laptop model.

Tinned Square Interface with Rotating Magnetic Head

The large square mouth features a tinned finish for durable conductivity and the magnetic hold is strengthened by the 8 pin contact design. In daily use the 360 degree swivel lets the cable run neatly behind the laptop or to the side without strain. The blind mating action means you can connect it in low light or by feel, and the magnetic breakaway protects the port if the cord is pulled.

Questions about this item

What comes in the box and do I need any extra cables to use the magnetic DC round head adapter?

The package contains the Big Square USB magnetic adapter with its 360° rotating head and 8‑pin magnetic contact; no separate cable is required because the USB plug connects directly to a power source.

Which connector version should I pick for my ThinkPad or Xiaoxin laptop — the generous square mouth or the DC round head?

This single unit combines both interfaces: the large square mouth plugs into the USB port while the DC round head mates magnetically with the laptop’s charging socket.

What does the 360° rotation actually do when the adapter is plugged into a laptop?

The head spins a full 360 degrees so the cable can route in any direction without stressing the magnetic connection or the laptop port.
