Compatible Karaoke Power Adapter

This AC adapter replaces the original power supply for Singing Machine STVG785 and STVG785W karaoke systems. It accepts worldwide mains input from 100 to 240 volts at 50 or 60 hertz. The barrel tip connector matches the device power port. It is a non-OEM replacement built to meet CE, FCC and RoHS standards.

Buyers Needing Exact Voltage Match

This unit suits owners who have confirmed their machine requires the specified DC output and barrel tip size. It is not for buyers who cannot verify the connector polarity or voltage requirements. Users needing an official manufacturer part should look elsewhere. Anyone with a different model number should check compatibility before ordering.

Worldwide Input Voltage Range

The adapter operates on AC input from 100 to 240 volts at 50 to 60 hertz. This single specification determines whether the unit works with your local mains supply. Over-voltage and over-heat protection circuits are integrated for safe operation. Always confirm the DC output and tip dimensions match your device before connecting.
