Questions about this item

Does the 45 W adapter run hot or make noise when powering the Inspiron 15 P51F P55F all day?

The 45 W output is rated for continuous use with the listed Dell models; typical AC adapters of this class run warm but silent under normal load.

What else must I already own for this charger to work with my Inspiron 15 P51F P55F?

The unit includes the power cord; you only need a standard 100 V – 240 V wall outlet and the laptop’s original barrel connector.

Can I keep my older Dell 45 W brick as a spare alongside this 19.5 V 2.31 A adapter?

Yes — both supply 19.5 V at up to 2.31 A, so the older 45 W unit will safely power the same Inspiron 15 models.
