Genuine HP 45W 19.5V Power Adapter

This genuine HP adapter supplies 45 watts at 19.5 volts and 2.31 amps for compatible HP laptops. It includes a detachable power cord for immediate use. The unit is new and manufactured to original equipment specifications. Buyers needing a higher-wattage supply for larger workstations should look elsewhere.

Input Range and Safety Protections

The adapter accepts a universal input of 100 to 240 volts at 1.1 amps across 50 to 60 hertz mains frequencies. Built-in safeguards protect against incorrect voltage, short circuit and internal overheating. These features help maintain stable operation during voltage fluctuations. The fixed output voltage limits use to devices matching the 19.5 volt requirement.

Build Quality and Everyday Use

The housing is built with quality materials to withstand regular transport and daily connection cycles. A standard barrel connector mates securely with the laptop power jack. The included cord uses a common IEC C5 or C7 style plug for easy replacement. Minor cosmetic wear from handling does not affect electrical performance.
