Description:

The HP 19.5V 3.34A (65W) power adapter is commonly used for HP laptops, and the blue pin you’re referring to is likely the center pin of the barrel connector (also known as the DC jack or power port).

Here’s a brief description:

• Voltage: 19.5 volts
• Current: 3.34 amps
• Power: 65 watts
• Blue Pin: The “blue pin” typically refers to a specific type of connector, possibly related to the center pin of the barrel jack or a unique internal connection. Some HP adapters use a blue pin for signal purposes (such as for identifying or verifying the power source) or for polarity.

This type of adapter is typically used for many HP laptops, particularly mid-range models. It’s important to ensure that the pin size (barrel diameter) and the voltage match the laptop’s requirements for proper charging.
