3 Top Customer Questions & Concerns 🙋‍♂️

⚡ Can I use a 20V adapter on a 19V or 19.5V device? No. Electronic components are designed with specific voltage tolerances. Always match the Voltage (V) exactly to your device’s requirements to avoid permanent damage.

🛡️ Is this adapter grounded? Yes. By utilizing the 3-pin C6 cloverleaf inlet, this unit maintains a ground path when used with a compatible 3-pin power cord, which is essential for protecting sensitive equipment from electrical noise.

🔌 Does it include the wall power cord? This model features the C6 "Cloverleaf" inlet. While it is sold as the main power brick, you will need a standard 3-pin C5/C6 power cable (common laptop style) to connect it to your wall outlet.
