Notes:
- Check your original DC output V/A, which can be found on the label on the bottom of the original laptop or charger.
- Make sure that the output voltage and current of the charger are exactly the same as your original voltage and current.
- Check the original USB-C interface to ensure compatibility.
- If the above model does not have your product model, as long as the power output and connector are matched with our product, it can be used normally.
- Some laptops do not have a full-featured USB-C port, so they will not charge via USB-C because they may not support Power Delivery
- If the Type-C port on your device is very loose. This charger may not be compatible.

How to Use & Care for Your HP 45W 19.5V 2.31A Laptop Adapter?
- Connector Identity: This is the 4.5mm Blue Tip. Please verify your laptop uses this small tip rather than the older 7.4mm black barrel.
- Wattage Verification: This 45W charger is for thin-and-light models. If your laptop has a dedicated gaming GPU, we recommend the HTJ 65W or 150W Blue Tip series.
- Cable Care: Avoid tight coiling; use the included cable strap to maintain the integrity of the internal copper strands during transport.
FAQ (Frequently Asked Questions)
- Q: Is this 45W charger compatible with the HP Pavilion x360?
A: This is the standard power supply for the Pavilion x360 11, 13, and 14-inch series, requiring 45W. - Q: Can I use this for an HP Chromebook in a classroom setting?
