DELL AC-Adapter 90Watt 3Pin 4.5mm

The Dell RT74M is a 90 W AC adapter for powering compatible Dell laptops. It supplies 19.5 V at 4.62 A, for use as a dedicated laptop power supply rather than a general-purpose USB charger.

Its round, straight connector has a 4.5 mm outer diameter and 2.9 mm inner diameter, with a pin. Checking these dimensions helps identify the required connection format.

The black casing measures 130 × 50 × 33 mm, defining its footprint for a desk or laptop bag. The listing names selected compatible models: Inspiron 14 (7437), XPS 13 (9333), and Inspiron 13 (7348), for home, office, or portable setups.

Package contents: three-pole C5 power cable.
