How to use

Confirm the laptop’s required voltage, current and power values from the rating label on the bottom of the laptop. Ensure the adapter’s voltage matches within +/- 0.5 V and that its current (A) and power (W) ratings are equal to or higher than the laptop’s requirements. Attach the 3.0 × 1.0 mm plug to the laptop’s DC input, connect the adapter to a 220–240 V mains outlet and verify charging begins. Use the Velcro strap to tidy the cable and avoid sharp bends or pinching.

Recommendations

Use only the identical plug size (3.0 × 1.0 mm) for safe connection. If unsure, measure the original tip or compare manufacturer specifications. Avoid exposing the adapter to water, extreme temperatures or heavy mechanical impact. For long-term reliability, choose an adapter with equal or higher wattage than the laptop’s rating.
