Purpose and compatibility

This 75 W AC adapter replaces the original charger for compatible Sony Vaio and HP laptops. It suits users who need a reliable 19.5 V power source for daily work or study. Buyers who require a different voltage, a higher wattage rating or a connector other than 6.5 mm by 4.4 mm should look elsewhere.

Thermals and power draw

The unit accepts a wide 100 to 240 V input at 50 to 60 Hz and delivers a steady 19.5 V at 3.96 A. Under normal load it operates within its 75 W design envelope without excessive heat or audible fan noise. The included power cord matches the plug standard for your region.

Deciding specification

The barrel connector measures 6.5 mm outer diameter by 4.4 mm inner diameter, and this single dimension determines whether the adapter will fit your laptop. Verify the port size on your device before ordering.

Questions about this item

How do I connect the 6.5mm*4.4mm tip and the detachable power cord without damaging the pins?

Align the barrel connector with the laptop port and push straight in until it seats; then plug the supplied power cord into the adapter's IEC socket and into a 100-240V 50-60Hz mains outlet.

Which parts of this 75W adapter will need replacement after extended daily use?

The detachable mains cord and the DC cable near the barrel plug are the wear items; the adapter body itself has no user-serviceable components.

At what point does the 19.5V 3.96A output hit its thermal limit during continuous load?

The unit is rated for a steady 75W output; sustained operation at that level will trigger its internal over-temperature protection before the voltage drops.
