Direct replacement charger

This 65W AC adapter powers Dell laptops that use a round 4.5 x 3.0mm connector. It covers Inspiron 13, 14 and 15 models across the 3000, 5000 and 7000 series as well as matching part numbers such as 5558, 5755, 3147 and 7348. The unit delivers 19.5V at 3.34A and also supports 45W systems.

Flexible daily connections

A 14-foot power cord gives extra reach from wall outlets to a desk or bedside table. The package includes a converter cable that adapts the 4.5 x 3.0mm tip to a 7.4 x 5.0mm jack, so one brick fits two common Dell connector sizes. Black housing matches typical laptop aesthetics.

Upgrade from worn or lost units

It replaces a missing original charger or one with a frayed cable or failing tip. The jump is worth it when the old adapter no longer holds a secure connection or shows signs of overheating. Buyers who need a USB-C power source or a higher wattage brick for larger workstations should look elsewhere.
