It seems the power output you've provided, 19V 7.1A, exceeds the typical power ratings for HP laptop adapters. HP laptop adapters usually have a maximum power output of around 90 watts (W) or slightly higher.
However, if you're certain about the specifications, here they are:
- **Brand:** HP
- **Power Output:** 134.9 watts (19V * 7.1A)
- **Voltage:** 19 volts (19V)
- **Current:** 7.1 amps (7.1A)
- **Connector Size:** 5.5mm x 2.5mm
This adapter, with its higher power output, can potentially be used for HP laptops that require a 19V power supply with a current rating of 7.1A and use a connector with dimensions of 5.5mm x 2.5mm. However, it's crucial to verify compatibility with your specific HP laptop model before purchasing to ensure it will work correctly and not cause any damage.
Please double-check the specifications to ensure accuracy, as such high amperage might be uncommon for laptop adapters. If uncertain, it's advisable to consult with HP or a professional to confirm compatibility and safety.
