Universal AC-DC Adjustable Power Supply Collection - Multi-Voltage Adapters with Interchangeable Tips

Universal AC-DC Power Adapters & Multi-Voltage Power Supplies

  • Find the perfect replacement power supply for your household electronics. Our Universal AC-DC Adapter series features selectable voltage outputs (from 1.5V to 15V) and reversible polarity, making them compatible with routers, speakers, LED strips, and vintage electronics.

    How to Choose: > * Check Amperage: Ensure your device requires less than the "mA" rating of the adapter (e.g., a 600mA device can use our 1000mA adapter).

    • Verify Voltage: Set the adapter to match your device’s required voltage before plugging in.

    • Polarity: Our reversible tips support both Center-Positive and Center-Negative configurations.
