45W HP Laptop Charger

This 45-watt AC adapter supplies 19.5 volts at 2.31 amps through a 4.5 by 3.0 millimetre blue-tip connector. It accepts 100 to 240 volts at 50 to 60 hertz for worldwide mains use. The unit replaces original HP power cords for a wide range of Pavilion, Envy, Spectre and Stream notebooks. It is a new replacement part, not a battery.

For HP owners needing a spare or replacement

The adapter fits many 11, 13, 14 and 15 inch models including specific Pavilion, ProBook and EliteBook series listed in the compatibility data. Buyers whose laptops require a different voltage, amperage or tip size should look at another charger. It does not suit devices that use USB-C power delivery or proprietary connectors other than the stated blue tip.

45 watts for mainstream ultraportables

The 45-watt output comfortably runs typical ultraportables and mainstream 14 to 15 inch laptops during normal workloads and charging. Systems that demand higher power for discrete graphics or heavy sustained loads will exceed this adapter's capacity. Headroom is limited to the rated 45 watts.
