In this case, the compatible laptop is indicated clearly on the packaging of the adapter or in item description, so check for this information carefully.

Other adapters, such those produced by third party manufacturers, are designed for use with a broad range of laptops, including ones from multiple manufacturers. In these cases, it is important to check the voltage and power of the laptop, and compare it with the specification of the adapter.

Otherwise, the adapter cannot charge the laptop properly, especially while it is in use and may even cause damage to the machine or adapter.

For example, a product may indicate that it can be used with 15 V, 16 V, 18.5 V, 19 V, 20 V, 22 V, and 24 V laptops. Inspect this information closely.
