45W AC adapter for HP 15 series

This 45W AC adapter delivers 19.5V at 2.31A through a 4.5mm connector. It is built for HP 15-CS, 15-CP, 15-DA, 15-DB, 15-DY, 15-EF and 15-FD models. The unit accepts 100-240V input at 50-60Hz for worldwide use. Buyers needing a replacement charger for these specific series will find a direct fit.

Steady 45W output under load

The adapter maintains its rated 45W continuously while the laptop runs and charges the battery. It supplies a stable 19.5V 2.31A current during sustained workloads such as video playback or document editing. The 100-240V input range handles voltage fluctuations without shutting down. This behaviour suits daily office or home use where the charger stays plugged in for hours.

Check connector size and model number

Verify that your HP laptop requires a 4.5mm by 3.0mm barrel tip before ordering. Confirm the exact model number appears in the supported list, such as 15-cs3055wm, 15-dy2024nr or 15-fd0083wm. Units needing a different voltage, amperage or tip diameter will not work with this adapter. Buyers who want more power or a USB-C connection cannot use this unit.

Questions about this item

Does the 45W adapter run hot or make noise when it powers a 15-DY laptop all day?

The 45W unit delivers 19.5V at 2.31A from a 100-240V 50-60Hz input and has no fan, so it stays silent and only warms slightly under continuous load.

What must I already own for this 4.5mm charger to work with my HP notebook?

You need an HP laptop that accepts a 4.5mm × 3.0mm barrel connector and 19.5V input — models such as 15-DA, 15-DB, 15-DY, 15-EF or 15-FD series are listed as compatible.

Will this 45W brick charge an older 15-BS Pavilion x360 as reliably as the original supply?

Yes — the 15-BS0000 series is in the supported list, and the 19.5V 2.31A output matches the original 45W specification for that model.
