90 W AC Adapter for HP ProBook

This 90 W power adapter delivers 19 V at 4.74 A through a 7.4 x 5.0 mm barrel connector. It is designed for HP ProBook models including the 4330s, 4331s, 4430s, 4431s, 4435s, 6470B, 6475b, 6545b, 6550b, 6555b and 6560b. The unit accepts a universal 100-240 V input at 50 or 60 Hz.

Included US power cord and certifications

A 2-prong US power cord is supplied in the box so the adapter is ready to use without a separate cable purchase. The charger carries CE, UL and RoHS certifications, indicating compliance with common safety and environmental standards. The 2-prong design keeps the unit lighter and more compact than three-prong alternatives.

Verify connector and part numbers before ordering

Confirm that your original adapter lists an output of 19 V and 4.74 A and uses a 7.4 x 5.0 mm tip. Cross-reference the HP part numbers 384021-022, 463995-001, ed495aa or HSTNN-CBOX to ensure an exact match. If the voltage, amperage or jack dimensions differ, the adapter will not be compatible.

Questions about this item

How often will the 2-prong US power cord need replacing under daily use?

The included 2-prong US power cord is a standard IEC C7 lead; replace it only if the insulation cracks or the plug loosens — typically several years.

What thermal limit appears first when the adapter runs at 90 W continuously?

The brick is rated for 90 W output at 19 V 4.74 A; sustained full-load operation will hit its internal temperature ceiling before the 100-240 V 50/60 Hz input range becomes a constraint.

How much heat and fan noise does the 90 W brick produce on a desk all day?

The adapter has no fan; it relies on passive convection, so it runs silent and reaches warm surface temperatures typical for a sealed 90 W supply under continuous load.
