This GCROWN AC adapter delivers 45 watts at 19.5 volts and 2.31 amps for compatible HP laptops. It features a 4.5 x 3 mm barrel connector with a blue tip. The unit matches a long list of HP part numbers including 719309-001 and 741727-001. Condition is new.

Buyers with HP Stream x360 11, 13 or 14 series notebooks or Spectre x360 13-g and 13-m models can use this charger. It also covers select Pavilion 15-f and 15-n series units. Users whose devices need a different voltage, higher wattage or another connector size should look elsewhere.

4.5 x 3 mm Blue-Tip Connector Decides Fit

The barrel plug measures 4.5 millimetres outer diameter by 3 millimetres inner diameter and carries a blue tip identifier. This exact geometry must match the laptop charging port for the adapter to work. Verify the tip dimensions against the original charger before ordering.

Questions about this item

What does the 45 W rating mean when the adapter is powering my laptop?

The 45 W figure is the maximum continuous power the adapter can deliver at 19.5 V and 2.31 A, so it will run and charge compatible HP models within that limit.

How does the 4.5 × 3 mm blue-tip connector limit which HP laptops I can use this with?

Only HP notebooks that accept a 4.5 mm outer-diameter, 3 mm inner-diameter barrel plug with a blue centre tip will fit; the long part-number list confirms the exact Stream, Spectre x360 and Pavilion models.

What physical space do I need for the brick and cable to sit on my desk?

The adapter body is a compact rectangular brick with a fixed mains lead and a DC cable ending in the 4.5 × 3 mm blue tip, so allow room for the brick plus cable bend radius near the laptop port.
