What this adapter replaces

This 18.5V 6.5A 120W oval connector power adapter supplies clean, stable DC power to compatible HP and Compaq laptops. It is a direct replacement for a lost or failed original charger. The unit includes a UL certified power cord for immediate use.

Thermal protection and worldwide input

An IC based thermal protection circuit guards against overheating during normal operation. The adapter accepts 100 to 240V AC input, so it works on mains supplies worldwide without a voltage switch. Devices draw only the current they require up to the 6.5A maximum.

Build fit and cable management

The black brick measures 9.8 by 4.1 by 1.8 inches and weighs 14.4 ounces, fitting easily into a laptop bag or desk setup. Its barrel connector seats securely in the laptop's power jack. No additional drivers or configuration are needed — just plug the cord into the wall and the connector into the device.

Questions about this item

How do I install the oval barrel connector and what step do people often get wrong?

Plug the oval barrel connector into the laptop's power port and the IEC power cord into the adapter's AC inlet; the step often missed is confirming the laptop requires exactly 18.5V and no more than 6.5A before connecting.

What maintenance or replacement will this adapter need later?

The IEC power cord can be replaced with any standard UL-certified cord if it becomes damaged; the adapter itself has no user-serviceable parts and relies on internal IC-based thermal protection.

What limit appears first during sustained high-load use?

The 120W maximum output rating is the first limit; the built-in thermal protection will activate if the adapter overheats while delivering continuous loads near 6.5A at 18.5V.
