Fuente de alimentación Dell 240W 19,5V 3 polos modelo 450-AILT para portátiles compatibles

The Dell 240W AC adapter delivers a stable 19.5V output through a 3-pin plug designed for compatible Dell laptops. As an external power supply with a fixed 240W power rating, it supports high-demand systems that require sustained power for performance and charging. The adapter is intended as a direct replacement when the original adapter matches the same output voltage and connector type, providing a consistent power source for daily use.

Advantages

This 240W adapter provides a reliable and constant 19.5V output suitable for laptops with higher power requirements. Its 3-pin connection ensures a secure physical link to compatible laptop models. The external design simplifies installation and replacement without internal modifications. The fixed power rating reduces the risk of underpowering demanding components during intensive tasks, and the adapter is built to meet typical safety and thermal handling expectations for desktop-replacement-class laptop power supplies.

Suitable for

• Powering high-performance Dell laptops that require a 19.5V, 240W external supply
• Replacing a damaged or lost compatible external adapter with a matching connector and voltage
• Providing a stable power source for long work sessions, gaming, or heavy multitasking

How to use

Connect the adapter to a compatible laptop by aligning and inserting the 3-pin connector into the laptop’s power inlet until it seats securely. Plug the adapter’s AC cord into a grounded wall outlet or surge-protected power strip. Ensure the laptop’s power requirements match the adapter’s 19.5V and 240W rating before use. During operation, keep the adapter in a well-ventilated area and avoid covering it to maintain proper cooling. Disconnect the adapter by first unplugging from the wall outlet and then removing the connector from the laptop when powering down or transporting the device.

Recommendations

Verify the laptop’s voltage and connector compatibility prior to purchase. Use a surge protector to reduce the risk of damage from power spikes and avoid using the adapter in excessively humid or dusty environments. Regularly inspect the cable and connector for wear and replace the adapter if any damage is visible.
