Genuine 45W adapter for Chromebook 2

This Toshiba PA5192U-1ACA unit delivers 19V at 2.37A for a total of 45W. It is manufactured specifically for the Toshiba Chromebook 2 series including models CB30-B-00F, CB30-B3121, CB30-B3122 and CB30-B3123. The package includes a power cord for immediate use.

Replaces a lost or faulty original charger

If the factory-supplied adapter is missing, damaged or no longer holds a stable connection, this genuine replacement restores full charging capability. The jump is worth it when the laptop refuses to charge or shuts down under load because the old brick cannot maintain 45W output.

Verify the barrel connector and voltage match

Confirm that your Chromebook 2 requires 19V input and uses the same barrel jack as the PA5192U-1ACA. Check that your mains supply falls within the 100-240V 50-60Hz range. Ensure the device drawing power does not exceed the 45W rating of this adapter.
