Authentic 90W Dell Latitude Power Adapter

This authentic Dell 450-AAYQ adapter delivers 90 watts of power for compatible Latitude laptops. It serves as a direct replacement for a worn original or as a spare unit for a second location. The streamlined design reduces bulk in bags and on desks. A three-foot cord with an attached rubber strap simplifies packing and storage.

Suits Latitude E5 and E6 owners needing a spare

Professionals who move between home and office benefit from leaving one adapter at each desk. Travellers gain a lightweight backup that fits easily in a computer bag. Buyers whose laptops require a different wattage or connector type cannot use this unit. Users needing a longer cable run will find the fixed three-foot length restrictive.

90-watt output matches the energy demands

The adapter is rated at 90 watts, the figure specified for the E5250, E5440, E5450, E5540, E5550, E6440 and E6540. Confirm that the laptop in use appears on this compatibility list before purchasing. The correct wattage ensures stable charging and operation. No other specification overrides this single requirement.
