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

I tried a Pyramid power supply for my ham radio. During the test, the power supply could cause a ground loop, causing the radio's internal speaker to emit HELLA BUZZ. This happened at all radio power levels. But when transmitting I was told that no noise is transmitted. Which was amazing. Then the USB power port didn't even work! So, it's POS! And was returned. Don't waste your time and money, invest in something better! The pyramid is no longer the same.
