How to use

Connect the adapter to a mains outlet using the appropriate IEC power cable or plug (as supplied), then insert the DC connector firmly into the laptop’s power jack until it seats securely. Confirm that the laptop indicates charging or external power; some models show an LED or on‑screen battery icon. Avoid placing the adapter on soft surfaces that obstruct ventilation while in use.

Use only with devices that accept 19.5V and are rated for up to 65W to ensure correct operation.

Recommendations

Use the adapter with compatible Dell models that require 19.5V/3.34A input and a matching barrel connector. Keep the adapter and cables dry, avoid exposing the unit to extreme temperatures, and inspect cables regularly for damage. Replace the adapter if signs of overheating, exposed wires, inconsistent charging, or physical damage appear. When transporting, secure the cable to prevent strain on the connector and store the unit in a protective sleeve to extend service life.
