45W HP laptop charger

This 45 watt AC adapter delivers 19.5 volts at 2.31 amps through a 4.5 mm by 3.0 mm smart blue tip. It replaces the original power supply for many HP Pavilion, Stream, Envy, ProBook, EliteBook and Spectre notebooks. The unit accepts AC input from 100 to 240 volts at 50 to 60 hertz for worldwide use. It is built for owners who need a direct replacement charger.

4.5 mm barrel fit and voltage match

The connector size and output voltage must match the laptop's charging port and power requirements exactly. This adapter frees the user from hunting for a proprietary HP part number by covering a wide range of compatible model series listed in the specifications. It needs only a standard mains cable and a wall socket to operate. Builders who need a higher wattage unit or a USB-C power delivery connector cannot use this adapter.

Steady 45 watt output under load

The adapter maintains its rated 45 watt output continuously while the laptop charges and runs demanding tasks. Internal protection circuits guard against over-voltage, over-current and short-circuit conditions during sustained operation. The 100 to 240 volt input range ensures stable performance across different mains supplies without manual switching. Units that require more than 45 watts will not charge properly with this model.
