Review on 🔌 12 Amp Desktop Bench Power Supply: AC-to-DC Converter with USB Charging and Vehicle Cigarette Lighter Socket by Richard Counts

This product looked like what I needed for my ham radio power source. While it was powering the device, it wasn't working properly in the background. When using my radio, other listeners complained about the 60 Hz background hum. I literally spent weeks trying to figure out the source, from using an extension cord to grounding issues and a nearby freezer. Nothing will get rid of the noise. One night an old man said on the internet he was pretty sure it was the power supply. Well I took a big risk and bought another brand at a higher price. I got it, pocketed it and voila, the buzz was gone. I wanted to return this device for a refund, but I've already passed the refund availability date. So now I've lost $60 on a useless power supply. Please don't waste your money on this product, it's poor quality.
