E-buy 19.5V 3.96A 75W laptop AC adapter for Sony VGN-FE VGN-FE11H VGN-FE31Z VGN-FE550 VGN-FE550FM

Compatible Sony VGN-FE series

This 75 W AC adapter supplies 19.5 V at 3.96 A for Sony VGN-FE models including VGN-FE11H, VGN-FE31Z, VGN-FE550 and VGN-FE550FM. It accepts 100–240 V input at 50–60 Hz so it works worldwide with the included power cord. The 6.5 mm by 4.4 mm barrel connector matches the original laptop socket. The unit is new and covered by a 24-month warranty.

Sustained 75 W delivery

The adapter is rated for continuous 75 W output rather than a short burst, so it can power the laptop and charge the battery simultaneously during extended work sessions. Its wide input range handles voltage fluctuations without shutting down. The fixed 19.5 V 3.96 A output remains stable under load, avoiding the voltage droop that can throttle system performance. No active cooling is required for normal operation.

Thermals, noise and power draw

With no fan, the adapter runs silently in typical use. The external brick dissipates heat through its casing, staying within safe limits during continuous 75 W delivery. Power draw from the wall follows the 100–240 V 50–60 Hz specification, drawing only what the laptop requires plus normal conversion losses. The included region-specific cord ensures a secure mains connection without adapters.
