• 90W Performance Headroom: By using a 90W adapter for 60W or 65W laptops, the charger stays cooler and delivers more stable power during intensive tasks.
• Premium Capacitors: We utilize high-temperature Japanese-standard capacitors to ensure a service life of 3-5 years under daily office use.
• Global Safety Compliance: Fully certified for international distribution (UL, CE, FCC), meeting all legal standards for government and corporate IT supply.

How to Use & Care for Your Samsung 90W 19V 4.74A Laptop Adapter?

• Tip Identification: This is the 5.5mm x 3.0mm tip with a pin inside. It is distinct from the smaller 2.5mm or 3.0mm Samsung tips used on Ultrabooks.
• Power Sequence: Plug the AC cord into the wall first, then connect the DC tip to the laptop. This allows the internal surge protection to stabilize.
• Cooling: Do not cover the adapter with papers or fabric while in use. The 90W output generates natural heat that requires ventilation.
