  • UL-listed AC cord and built-in surge protection guard your laptop against power spikes
  • 90 W output replaces both 65 W and 90 W HP chargers without needing a 120 W unit
  • 100–240 V input works worldwide with no voltage selector needed

90W AC Adapter for HP Laptops

This 90 watt AC adapter from iTekiro replaces HP 65W and 90W chargers for a wide range of HP part numbers including E7N78UA, E7N79UA, E7Z36UA and E7Z50UA. It delivers 19.5VDC at 4.62A to power the laptop and charge the battery whether the system is on or off. The unit is sold new with a ruggedized case designed for mobile environments.

Input Range and Cord Length Limits

The adapter accepts AC input from 100 to 240V at 50 to 60Hz for worldwide compatibility without a voltage selector. It includes a UL listed 2-prong AC power cord measuring 6 ft and a DC output cord also measuring 6 ft for a combined reach of 12 ft. The brick dimensions are 4.25" x 1.89" x 1.18" and the package weighs 10.8 oz.

Replaces 65W and 90W HP Chargers Only

This unit directly replaces HP 65W and 90W adapters but does not replace a 120W adapter, so buyers needing 120W output must choose a different model. The jump is worth it when your original HP charger is lost, damaged or you want a spare with extra long cords for flexible desk placement. It is not for users who require a higher wattage brick or a different output voltage.
