Questions about this item

Does the 120W 19.5V 6.15A adapter run hot or make noise during all-day use?

The unit includes over-current, over-voltage, short-circuit and total-power protection to limit heat buildup, and it has no moving parts so it operates silently.

What must I already own for this 7.4mm x 5.0mm tip to work with my laptop?

You need an HP Envy model that accepts a 7.4 mm by 5.0 mm barrel connector and draws 19.5 V at up to 6.15 A, plus a standard earthed mains socket for the supplied US three-prong cord.

Will this 120W replacement power my older HP Envy dv6-7300 alongside a newer dv4-5300?

Yes, the adapter matches the 19.5 V 6.15 A requirement and 7.4 mm x 5.0 mm tip used by both the dv6-7300 series and the dv4-5300 series listed in the compatibility table.
