Compatible Replacement Adapter

This WAWEIS AC adapter replaces the original power supply for the VIZIO SB4021E 40 inch sound bar. It matches the required output and connector so the speaker system powers on and operates normally.

Check Connector And Voltage Match

Verify that the existing unit uses the same barrel connector and polarity before ordering. The adapter accepts 100-240VAC at 50/60Hz worldwide input, so mains voltage compatibility is broad.
