Genuine HP 45 W AC adapter

This genuine HP 45 W AC adapter delivers 19.5 V at 2.31 A for compatible HP laptops. It accepts a wide 100-240 V input at 50-60 Hz so it works on mains supplies worldwide. The unit includes a power cord and carries the manufacturer part numbers 740015-002 and 854054-003. Built-in safeguards protect against incorrect voltage, short circuit and internal overheating.

Suits owners of 45 W HP notebooks

It suits owners of HP notebooks that require a 45 W, 19.5 V power source with the matching barrel connector. Buyers whose devices need a higher wattage rating or a different voltage should look at another adapter. Anyone who has lost or damaged their original charger can use this as a direct replacement. The included cord means no separate cable purchase is necessary.

Steady 45 W output under load

The adapter maintains its rated 45 W output continuously while the laptop is running and charging the battery. Protection circuits for over-voltage, short circuit and over-temperature activate automatically if a fault occurs. The 100-240 V input range handles voltage fluctuations without shutting down. It is designed for sustained daily use rather than short bursts only.
