90W AC charger with 7.4mm tip fits many Dell Latitude, Inspiron and Precision models
This charger is a direct replacement for a wide range of Dell Latitude, Inspiron and Precision laptops. It supplies 90 watts of power through a 7.4 mm barrel tip that matches the original connector. The unit is sold new and ready to use as a primary or spare power source for compatible models.
The adapter works with Latitude models such as the E7440, 7450, 5500, E6520 and 5400 series as well as Inspiron 14R, 15R, 17R and 13z families. It also covers Precision 3530, 3540, 3550 and 3551 workstations. A single charger can serve several of these devices, reducing the number of power bricks needed in a mixed fleet.
The brick delivers its full 90 W output without a fan, so operation is silent in normal use. Heat is dissipated through the case surface, keeping temperatures moderate during typical office workloads. Power draw from the wall matches the rated output plus normal conversion losses.
