  • Four-pin connector matches HP part 5066-2164

HP-Compatible 56V 1.6A Power Adapter

This 56-volt, 1.6-ampere AC adapter replaces the HP HSTNS-XXX 5066-2164 and PA-1900-2P-LF units. It delivers 1202000132 specification power through a four-pin connector. The unit is built for laptops that require the exact voltage and pin layout listed. It is not for machines needing a different voltage, amperage or connector count.

1.6A Output With Four-Pin Delivery

The adapter supplies a steady 1.6 A at 56 V, matching the original equipment power envelope. That headroom covers the charging and operational load of the compatible HP models. It runs out when a system demands higher current or a different voltage rail. Buyers whose laptops specify a larger current draw or an alternate pin arrangement should look elsewhere.

New OEM-Match Build With Four-Pin Plug

The adapter is new and guaranteed to meet the original device specifications. Its four-pin plug mates directly with the laptop's power jack without adapters or soldering. The fixed cable length and strain relief are designed for daily connect-disconnect cycles. It is not for users who need a barrel connector, USB-C power delivery or a modular cable system.

Questions about this item

Will the 4 PIN connector on this 56 V 1.6 A adapter fit the charging port on my older HP laptop that used the HSTNS-XXX brick?

The adapter uses a 4 PIN connector designed for HP models referencing HSTNS-XXX and part 5066-2164, so it matches the same port your older unit used.

How can I verify the PA-1900-2P-LF replacement is delivering the correct 56 V output after I plug it in?

The brick is rated at 56 V and 1.6 A; a multimeter on the 4 PIN plug should read close to 56 V with no load, and the laptop charging indicator should light normally.

Does the CN21XXX048 unit come with a mains lead or only the 1202000132 power brick itself?

The package contains the 56 V 1.6 A adapter with 4 PIN output; a compatible IEC C5/C6 or C7/C8 mains cable must be purchased separately if you do not already have one.
