Warm prompt:

1.Before you buy, make sure your DC output and connector size match your original adapter.

2.Output voltage and polarity must match your old adapter.

3.The output current is not as critical as the output voltage, and you can choose the same or higher output current adapter.

4.Press Ctrl+F and enter your model to see if it is in the list. If the three tips above are the same as your adapter, you can ensure that our adapter is compatible, even if your model is not listed. You can check the output voltage and output current on the label on the bottom/back of the original charger or laptop.Regarding polarity (connector dimensions), you can measure or compare with ours.
