BULL-TECH 130W 7.4mm Dell Laptop AC Adapter

BULL-TECH 130W Replacement AC adapter is a direct-fit power charger that delivers 19.5V at 6.7A through a 7.4mm x 5.0mm tip for compatible Dell laptops and docking stations.

This BULL-TECH replacement charger is engineered to match the power profile of many Dell models that use the larger 7.4mm barrel connector, offering a reliable 130-watt output for notebooks, docking stations, and business-class systems. It accepts universal AC input (100–240V) so it works worldwide with the proper plug, and it ships with a three-prong power cord to connect to mains outlets. Before ordering, verify your laptop’s power requirements and confirm the 5.0mm x 7.4mm connector size to ensure compatibility.
