Compatible Latitude models

This genuine Dell 90W AC adapter powers Latitude D800, E5400, E5440 and E5530 laptops. It includes the AC power cord for immediate connection to a mains outlet. The unit is supplied new and built to Dell specifications for those notebook families.

Thermals noise and power draw

The adapter accepts 100-240V input at 1.5A across 50-60Hz and delivers a steady 19.5V at 4.62A. Built-in safeguards protect against incorrect voltage, short circuit and internal overheating during normal operation. No active cooling fan is present so the unit runs silently.

Upgrade considerations

This adapter replaces a lost or faulty original charger for the listed Latitude models. It is not suitable for laptops that require a higher wattage or a different output voltage. Buyers needing power for other Dell series or non-Dell notebooks should verify compatibility before purchase.

Questions about this item

How do I connect the 90W adapter to my Latitude E5440 and what step is often missed?

Plug the barrel connector firmly into the laptop's DC-in jack until it seats fully, then attach the supplied power cord to the adapter brick and a 100-240V 50-60Hz wall outlet; the step often missed is ensuring the cord clicks into the brick before powering on.

What part of this 19.5V 4.62A adapter will need replacement first with daily use?

The detachable power cord and the barrel-connector cable see the most flexing, so they typically wear out before the sealed 90W brick itself.

What limit appears first when this 90W unit runs continuously at full load?

Internal overheating protection (IO) will throttle or shut down the adapter if sustained 90W draw causes the brick temperature to exceed its safe threshold.
