### ⭐ Garbage doesn't work
*by B***B on September 12, 2026*

Doesn't work. Checked with a multimeter. Proper 12 volts going in, nothing on the output. Garbage. Do not buy

### ⭐⭐⭐ I don’t know it seems to work
*by M***T on June 2, 2024*

I don’t know yet it seems to work

### ⭐ Dead on arrival.
*by R***. on October 31, 2024*

Connected this to a 12 volt power source expecting the stated 3 volt output, but got ZERO volts. Disconnected and checked continuity: nothing. If you risk buying this, make sure you check it with a digital multimeter before wiring it into your project. I've tried the adjustable step down transformers here on Amazon, but can't get any of them adjusted below 3.2 volts, and I need exactly 3 volts. I returned this defective converter and ordered "12V-24V to 3V 5A Transformer Step Down Module Power Converter Voltage Regulator" (ASIN: B0D5DMHS7J) hoping for better luck when it arrives in a week or two from China.
