When it may not be suitable

This power adapter is not compatible with laptops that require a different voltage, power rating, or a connector size other than 0.7 mm. It should not be used with devices that demand a higher power output than 40 W, as this may lead to insufficient charging performance or equipment malfunction.

Disconnect the adapter from the power outlet when the device is fully charged or not in use for extended periods.

What to consider before purchase

  • Verify your laptop exact model and power input requirements
  • Check that the connector diameter of 0.7 mm matches your device
  • Confirm that the 40 W power output and 2.1 A current align with your original equipment specifications
Always verify connector compatibility and electrical parameters with your specific laptop model before connecting any power supply to prevent potential device damage.
