- HP Notebook Charger: The power output of the charger is typically measured in watts (W), calculated by multiplying voltage (V) by current (A). Common wattages for HP laptops are:
- 45W: Used for smaller and more portable models (e.g., HP Pavilion, HP Stream).
- 65W: Common for mainstream laptops like HP Spectre, HP Envy, HP ProBook.
- 90W: Needed for high-performance models like HP Omen or other gaming laptops.

Finding the Right 19V Charger:
To ensure that you purchase the correct charger, follow these guidelines:
- Check the Laptop’s Power Requirements:
- Look at the power adapter label on your original charger or check the laptop’s manual for the exact voltage and amperage requirements.
- The voltage should be 19V, but the amperage (A) can vary. For example:
- HP laptops often use 3.42A for 65W chargers or 4.74A for 90W chargers.
- Ensure Wattage Match:
- A 65W charger is generally sufficient for most laptops, but gaming or performance-oriented HP laptops may need 90W, 120W, or even 150W.
- Make sure the charger you’re buying matches the required wattage of your laptop to avoid issues like slow charging or overheating.
- Original HP Charger vs. Third-Party Charger:
- Official HP chargers are recommended for compatibility and safety, as they are designed specifically for HP laptops.
- If you choose a third-party charger, ensure it supports the correct voltage (19V) and amperage for your laptop. Be cautious, as low-quality third-party chargers might not have the necessary safety features or could cause damage to the laptop.

How to Identify the Correct HP 19V Charger:
- Look at the Output Label: Your original charger or laptop usually has a label that lists the required voltage (19V), amperage (e.g., 3.42A for a 65W charger), and connector type.
- Connector Type: Verify the size of the round barrel connector. Common sizes for HP laptops are:
- 4.5mm x 3.0mm: For many HP laptops.
- 7.4mm x 5.0mm: For some HP laptops, particularly higher-end models.
