Dell 90W Adapter for Latitude Laptops

This genuine Dell 90W AC adapter delivers 19.5V at 4.62A for compatible Latitude models including the 2110, 3440 and D400. It accepts a universal 100-240V input at 50-60Hz and ships with a power cord included. The unit is manufactured by Dell specifically for Dell Latitude laptops.

Replaces Lost or Failing Dell 90W Units

The adapter serves as a direct replacement when the original charger is lost, damaged or no longer holds a reliable charge. The upgrade is worth it when the existing power supply shows intermittent operation, physical cable wear or cannot maintain the required 90W output under load. Built-in safeguards protect against incorrect voltage, short circuit and internal overheating.

Limits of 90W Barrel-Type Power Delivery

The 90W rating caps the maximum power available to the laptop and any attached peripherals drawing from the same rail. The barrel connector and fixed 19.5V output restrict use to devices designed for this exact voltage and connector geometry. Buyers needing higher wattage, USB-C Power Delivery or a different voltage rail cannot use this adapter.
