Replacement adapter for Sony PCG-R505 series

This 19.5V 3.96A 75W AC adapter replaces the original charger for Sony PCG-R505Ex, PCG-R505G, PCG-R505GC, PCG-R505GCK and PCG-R505GCP laptops. It accepts 100 to 240V input at 50 or 60Hz for worldwide use. The unit is sold new with a 24 month warranty.

Cooling and power behaviour

The adapter delivers a steady 19.5V DC output at up to 3.96A without active cooling. Passive heat dissipation keeps the enclosure warm but silent during typical charging loads. Power draw at the wall scales with the 75W output rating and the connected laptop's demand.

Included cable and connector

A detachable mains cord with a US, UK, EU or AU plug is supplied to match the destination country. The DC side terminates in a 6.5mm by 4.4mm barrel connector that fits the listed Sony models. The package contains the adapter and the power cord only.

Questions about this item

How do I install the 19.5V 3.96A adapter on my Sony PCG-R505Ex and what step is often missed?

Plug the 6.5mm × 4.4mm connector firmly into the laptop's DC jack until it clicks, then attach the supplied country-specific power cord to the adapter's IEC inlet and a 100–240V 50–60Hz mains socket. The step often missed is fully seating the barrel plug so the centre pin makes solid contact.

What maintenance or replacement will the 75W AC adapter need later?

Inspect the DC cable and 6.5mm × 4.4mm plug for fraying or bent pins every few months; replace the whole unit if the cord is damaged, the adapter becomes unusually hot, or output voltage drifts from 19.5V under load.

What limit appears first when the 19.5V 3.96A adapter runs continuously at full load?

The 75W thermal ceiling is reached first; sustained 3.96A output raises internal temperature until protection circuitry may throttle or shut down the adapter to prevent overheating.
