Compatible Asus Vivobook models

This replacement AC adapter fits the Asus Vivobook V550CA-OB91T, X550LA-XH51, X501A-SI30302Q and R503U-RH21 ultrabooks. It supplies 19 V output for daily charging and general use. The unit includes the mains power cord for immediate connection.

Plug-in installation

The adapter uses the standard barrel connector found on the listed models, so no tools or internal work are required. A common issue is a loose or worn DC jack on the laptop itself, which can cause intermittent charging even with a new adapter. Inspect the port for damage before assuming the power supply is at fault.

Check your laptop label

Verify that the original charger shows an output of 19 V and that the tip size matches the port on your device. Confirm the model number on the base stencil matches one of the supported designations above. The adapter accepts 100-240 VAC input at 50/60 Hz for worldwide use.
