Compatible 19 V adapter for Asus Q550LF-BSI7T21
This 19 V AC adapter is a brand-new replacement charger for Asus Q550LF-BSI7T21, V551LA-DS71T and K550CA-RS51T laptops.

Suitable for owners of those specific models who need a direct replacement power supply.
Check connector and model before ordering
Verify that your laptop is one of the three listed models and that the original charger specifies 19 V output. The adapter ships with a standard power cord; confirm the wall-plug style matches your region or have a suitable cord ready. No other voltage or connector variants are supplied with this unit.
Replaces lost or faulty original chargers
This unit replaces the factory AC adapter when the original is lost, damaged or no longer holds a charge. The upgrade is worth it when the existing supply shows intermittent charging, physical cable wear or has failed completely. Not for buyers who need a higher-wattage supply, a USB-C power source or a multi-voltage travel adapter.
