HP 317188-001 120 W Notebook Adapter

This HP AC adapter delivers 18.5 V DC at up to 6.50 A for compatible notebooks. It replaces the original charger when the factory unit is lost or damaged. The multi‑color housing matches several HP product lines. Buyers who need a higher wattage unit or a different output voltage cannot use this model.

Sustained 120 W Output Behaviour

The adapter is rated for a continuous maximum of 120 W rather than a brief peak. Under full load the 18.5 V rail remains stable while the current reaches 6.50 A. Thermal protection engages if the internal temperature exceeds safe limits. Users running demanding workloads for long periods should ensure adequate ventilation around the brick.

Barrel Connector Interface Limits

Power is transferred through a standard barrel plug that fits the listed OEM part numbers. The connector polarity and dimensions are fixed by the notebook design, so the adapter cannot charge devices that require a different tip size or USB‑C Power Delivery. Builders needing multiple simultaneous outputs or a detachable cable system must look elsewhere.

Questions about this item

Does the 317188-001 adapter stay cool and quiet when powering a notebook all day?

The 120 W unit delivers 18.5 V DC at up to 6.50 A with no moving parts, so it runs silently and produces only normal warmth for its power rating.

What must I already have to use this 317188-001 adapter with my HP notebook?

You need a compatible HP notebook that accepts 18.5 V DC input and a mains cable with a C5 connector to plug the adapter into the wall.

Will the 317188-001 work alongside the older HP part numbers listed such as 316687-001 or 393946-001?

Yes, the adapter replaces all listed OEM numbers including 316687-001, 316688-001 and 393946-001, so it fits the same notebooks those bricks originally shipped with.
