Why Choose HTJ Certified Gateway 65W 19V 3.42A Laptop Adapter?

• Universal Tip Engineering: The 5.5×2.5mm connector is precision-molded to provide a high-tension fit for both 2.1mm and 2.5mm center pins, eliminating “loose-fit” charging issues.
• 65W Stability Reserve: This unit provides a steady 3.42A, making it a “Cooler-Running” replacement for 40W and 45W laptops, extending the lifespan of both the adapter and the battery.
• 100% Load Tested: Every HTJ unit undergoes a 4-hour full-load burn-in test to ensure 0% DOA (Dead on Arrival) for large B2B shipments.
• High-Purity 18AWG Copper: Our DC cables use thicker copper strands to ensure zero voltage drop over the 1.5M cable length. 

How to Use & Care for Your Gateway 65W 19V 3.42A Laptop Adapter?

• Check Your Tip: This is the 5.5mm x 2.5mm round barrel. It is the most common 19V size. Verify your laptop doesn’t require the smaller 3.0mm or 4.0mm tips used on newer ultrabooks.
• Wattage Logic: It is perfectly safe to use this 65W adapter on laptops requiring 40W, 45W, or 65W. Do not use it on 90W gaming laptops.
• Storage: Use the integrated cable tie to secure the cord. Avoid wrapping the cord tightly around the brick to prevent strain on the internal connections.
