Top 3 Customer Questions & Concerns 🙋‍♂️

⚡ Can I use this for a laptop that only needs 20V 3.25A? Yes. Your device only "draws" the amperage it requires. This 4.5A capacity adapter provides extra headroom, allowing it to run cooler and more efficiently than a lower-rated supply.

🛡️ Is this adapter grounded for safety? Yes. The 3-pin clover leaf (IEC C6) inlet ensures the adapter and your hardware are properly earthed when used with a grounded power cable, protecting against static and surges.

🔌 Does it include the wall power cord? This unit features an IEC C6 inlet. To connect it to a wall outlet, you will need a matching 3-pin clover leaf power cable that fits your regional socket (e.g., UK/Malaysia 3-pin).
