Compatible HP Laptop Models

This 30W AC adapter replaces the original charger for HP laptops matching part numbers NB137UAR, NT383EA, NT383EAR, NP767EA, NT386EA and NS527EA. It delivers the exact 19V 1.58A output those notebooks require. The unit ships new with a region-appropriate power cord included.

Power Delivery And Connector Fit

The adapter supplies 19 volts at 1.58 amps for a continuous 30 watts, accepting 100 to 240 volts at 50 to 60 hertz from any mains supply. A 4.0mm by 1.7mm barrel connector ensures a secure fit on the listed HP models. It is not suitable for laptops that demand higher wattage or a different tip size.

When This Charger Is The Right Upgrade

Choose this unit when the original HP power supply is lost, damaged or no longer holds a stable voltage. The 24-month warranty covers defects in materials and workmanship. Buyers whose notebooks specify a larger current rating or a different connector diameter will need a different adapter.

Questions about this item

Will this 19V 1.58A adapter safely replace the original charger for my HP NB137UAR laptop?

Yes, the adapter matches the 19V 1.58A 30W specification and the 4.0mm by 1.7mm connector required by the HP NB137UAR, NT383EA, NT383EAR, NP767EA, NT386EA and NS527EA models listed.

How can I confirm the adapter is delivering the correct 19V output after I plug it in?

The unit accepts 100 to 240V AC at 50 to 60Hz and regulates a steady 19V DC at up to 1.58A; a multimeter on the DC plug should read close to 19V when the laptop is connected and charging.

Does the package include both the power brick and a mains cord for UK sockets?

The box contains one AC adapter and one power cord; the cord supplied matches the destination country, so a UK plug version will be included for UK delivery.
