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.

Awesome experience

Web site was very helpful to make sure I had the right replacement plug and it arrived in a few days.
Had to cut the plug end off to replace a hard wired plug from an old Halloween decoration but it worked and saved a 25 year old holiday decoration.

Variable Isolated Transformer 10A (1000W) 0–130VAC with LCD Voltmeter | SC-10T-2
What an INCREDIBLE deal, what service!!! I'm be buying more!

I bought the Variac/isolation transformer combo. FOR STARTERS: NOBODY ELSE MAKES THIS COMBO with a genuine isolation transformer. And that fact that it's $200 out the door is insanity. My only advice with the unit would be to double check the voltage display against a multimeter; I find my display to be about 5V lower than the actual output and adjusted accordingly.

This item was packaged more securely than a nuclear warhead. Seriously, the packing job is a masterclass in transportation and logistical safeguards.

In short--I rarely leave reviews. I felt I HAD to for this product. If you're not sure because it's a newer item/company, don't worry. They are LEGIT and they are INCREDIBLE.
One more side note--customer service response is insanely fast also. I emailed a question on a SUNDAY EVENING and got an answer.

GREAT, domestically-owned small business I will support again.
