Replacement AC adapter for Compaq Presario CQ series
This 65 W adapter supplies 18.5 V at 3.5 A and accepts a universal 100-240 V input at 50-60 Hz. It is built as a direct replacement for the original charger used with Compaq Presario CQ40, CQ45, CQ50, CQ56, CQ60 and CQ61 notebooks. A detachable power cord is included in the package.
Continuous output within the rated limits
The unit is designed to deliver its full 65 W continuously while the laptop is running and charging the battery simultaneously. Thermal protection circuitry maintains stable voltage under sustained load without tripping or throttling. The 18.5 V output remains steady as long as the connected device draws within the specified 3.5 A maximum.
Barrel connector size determines compatibility
The plug measures 7.4 mm outer diameter by 5.0 mm inner diameter, a dimension that must match the laptop’s DC jack exactly. Cross-reference the listed part numbers such as ED494AA#ABA, 391172-001 and PA-1650-02HC before purchasing. If the jack size or pin layout differs the adapter will not connect or power the system.
