HP 135W AC adapter for Pavilion and Presario
This HP HSTNN-LA01-E adapter supplies 135 watts at 20 volts and six amps to compatible HP Pavilion and Compaq Presario notebooks. It accepts a universal 100 to 240 volt input at 50 to 60 hertz for worldwide use. The unit includes the power cord and matches the original equipment specifications. It serves as a direct replacement or a spare charger for home and office.
Suits owners of listed HP
Buyers with laptops that require a different output voltage or a higher wattage rating should look elsewhere. The adapter is not for devices that use a proprietary connector not covered by the listed part numbers. Users needing a USB-C power delivery solution will not be served by this barrel-style unit.
Output fixed at 20V 6A 135W
The single deciding specification is the 20 volt six amp output delivering exactly 135 watts. Verify that the target notebook lists one of the compatible part numbers such as 647982-002, 397747-001 or PA-1131-08HC before purchasing. A mismatched voltage or wattage will prevent correct operation.
