90W AC adapter for Inspiron and Latitude

This 90W AC adapter supplies 19.5V at 4.62A for a wide range of Dell Inspiron and Latitude laptops. It accepts a universal 100-240V input at 50-60Hz and includes both 7.4 x 5.0 mm and 4.5 x 3.0 mm connector tips. The unit is new and ships with an AC power cable.

Continuous 90W delivery with integrated protection

The adapter is rated for a sustained 90W output rather than a short-term peak. An internal IC chip provides overcurrent, overvoltage, overheating and overcharge protection during extended charging sessions. CE, FCC and RoHS certifications confirm compliance with safety and environmental standards.

Dual-tip 7.4 x 5.0 mm and 4.5 x 3.0 mm connector

Compatibility hinges on the laptop requiring one of these two barrel sizes and a 19.5V input. Machines that use a different tip diameter, a USB-C power input or a higher wattage brick will not work with this unit.

Questions about this item

Does the 90W adapter run hot or make noise when used all day?

The unit delivers 19.5V at 4.62A with built-in IC protection against overheating, overcurrent and overvoltage, so it stays within safe thermal limits during continuous operation.

What must I already own for this charger to work with my laptop?

You need a Dell laptop that accepts a 7.4 x 5.0 mm or 4.5 x 3.0 mm barrel connector and draws up to 90W; the package includes the AC adapter and a detachable mains cable.

Will this 90W unit charge an older Latitude E6410 or Inspiron 15R (7520) without issues?

Yes — the adapter is listed for Latitude E6410, E6420, E6430, E6440 and Inspiron 15R (7520) among many other models, so it will power those legacy systems at the rated 90W.
