Universal Power Converter 50A Adjustable 12-15V 2 USB Ports Overload Protection

It’s a good looking piece of equipment. It’s light weight and it’s powerful and does the job. But the biggest problem is that this piece of equipment is very noisy. It causes unwanted interference in every other electronic around it. I bought it to hook up a powerful radio, but it creates so much noise. You can’t hear the other person you want to talk to. You’re better off running a regular 12 V car battery.
