45W 19.5V Blue Tip HP Adapter

This 45-watt AC adapter delivers 19.5 volts at 2.31 amps to compatible HP laptops. It accepts 100-240V input for worldwide use and includes a standard power cord. The unit is designed as a direct replacement for original chargers that share the same output and connector specification.

4.5mm x 3.0mm Blue Tip Connector

The proprietary blue tip connector measures 4.5mm by 3.0mm and fits supported HP notebooks without adapters. A detachable power cord allows compact storage and easy replacement if the cord is damaged. Built-in short-circuit protection helps safeguard the laptop and adapter during daily charging at home or on the move.

Replaces 45W HP Original Chargers

This adapter replaces lost or faulty HP 45W units with part numbers such as 741727-001, 719309-001 or PA-1450-36HE. The jump is worth it when your original charger fails and you need a matching 19.5V 2.31A output with the exact blue tip fit. It is not for laptops that require higher wattage, a different voltage or a non-blue tip connector.
