It supports worldwide AC input (100–240 V, 50–60 Hz) and is built to match the power profile of many HP notebooks that originally used 45 W adapters. Before ordering, confirm your laptop’s required wattage and tip size — this unit is not compatible with 65 W, 90 W, 7.4 × 5.0 mm barrels, or USB-C power ports.\u003c\/p\u003e\n\n\u003ch3\u003eWhich HP models will this ROLADA charger work with?\u003c\/h3\u003e\n\u003cp\u003eThis adapter is engineered to fit a long list of HP Stream, Pavilion and ProBook models that use a 4.5×3.0 mm barrel tip and require 19.5 V at about 2.31 A.
