Tips :
    What should I pay attentiion to when using a notebook power adapter?
  • 1, create a good cooling environment
  • When using the notebook in a high temperature environment, place the power adapter in a place that is not exposed to direct sunlight and ventilation; do not place the power adapter near the cooling air outlet of the notebook; at the same time, we can put the adapter on the side to make the heat more Well distributed.
  • 2. If the voltage is unstable, it needs to be stopped in time.
  • Although the adapter is a wide-band operating voltage, it can be marked from 100V to 240V, but if it is used under extremely unstable voltage, it will also cause serious heat or damage to the power adapter.
  • If you need to temporarily borrow power from other brands, try to choose an adapter with the same or larger output current.
  • 3. If an abnormality occurs, stop using it in time.
  • When you are not using the adapter, unplug the power cord. Prolonged power-up will keep the adapter working and will affect the end of life. When the power adapter emits large working noise or even smoke, it is often damaged or has a fault. It should be stopped immediately and can be used again after being repaired by professional engineers.
