What this charger powers

This 45W AC adapter delivers 19.5V at 2.31A for HP 15-F series laptops and the extensive list of compatible models including 15-CS, 15-CP, 15-DA, 15-DB, 15-DY, 15-EF and 15-FD ranges.

Who should buy this and who should not

It suits owners of the listed HP 15 series notebooks who need a direct replacement for a lost or faulty 45W charger. It is not for laptops that require a different voltage, a different connector size or a higher output power than 45W. Buyers with models outside the compatibility list should verify their original adapter specifications before purchasing.

The spec that decides fit

Output is fixed at 19.5V and 2.31A for 45W total power through a 4.5mm by 3.0mm barrel plug. Match both the voltage and the connector dimensions to your laptop's original adapter to confirm compatibility.
