Genuine Dell 65W AC adapter for compatible laptops

This genuine Dell power adapter delivers 65 watts at 19.5 volts and 3.34 amps through a 5.5 by 2.5 millimetre barrel connector. It is built for Dell laptops that require this exact output and tip size. The unit includes a detachable mains cord for immediate use. Buyers needing a higher-wattage brick or a USB-C power source should look elsewhere.

Simple plug-in replacement with built-in safeguards

Connect the barrel tip to the laptop and the IEC cord to a wall socket; no drivers or configuration are required. The adapter accepts 100 to 240 volts at 50 to 60 hertz, so it works worldwide with only a cord change. Common issues arise when the tip size or voltage does not match the original unit, causing the laptop to reject the charger.

Steady 65-watt output during extended sessions

The adapter maintains its rated 19.5-volt, 3.34-amp output continuously while the laptop charges and runs demanding workloads. Internal protection circuits guard against incorrect voltage, short circuit and internal overheating during prolonged operation. The brick is designed to stay within safe thermal limits without external cooling.
