Targeted Replacement Power

This 240W AC adapter is built specifically for the Dell Alienware 17 R4 notebook. It delivers the required 19.5V at 12.3A output through a compatible connector. The unit serves as a direct replacement for a lost or damaged original charger. Buyers needing a different voltage, amperage or tip size for another laptop model should look elsewhere.

Sustained Load Behaviour

The adapter accepts a wide 100-240VAC input at 50/60Hz for global mains compatibility. Integrated safety circuits provide over current, over voltage, short circuit and total power protection during continuous operation. A smart chip manages overheating protection while anti-interference materials maintain stable delivery. The 10 ft power cord allows flexible placement without tension on the connection.

Build Quality & Daily Use

The charger uses high-quality wires and isolation materials tested under strict quality control standards. FCC, CE and RoHS certifications confirm compliance with safety and environmental regulations. All components are new and manufactured to meet original equipment specifications. The 10 ft cable length supports convenient desk or floor routing in everyday scenarios.
