How to use

Connect the adapter's AC plug to a mains outlet and insert the DC barrel connector into the laptop's power jack rated for 19V input. Ensure the connection is fully seated and the power indicator on the laptop (if present) confirms charging. Avoid placing the adapter on soft surfaces while in use to maintain ventilation. When unplugging, grasp the connector rather than pulling on the cable to reduce strain.

Recommendations

Use this adapter with laptops that specify 19V and a compatible current rating; verify the connector fits your device before use. Operate the adapter in a dry, well-ventilated environment and avoid exposing it to extreme temperatures or moisture. If the adapter becomes unusually hot, emits noise, or shows visible damage, discontinue use and replace it.
