Review on 💡 JOVNO Universal Power Supply: Adjustable AC/DC Adapter 4V-12V 10A 120W with LED Display & 14 Plugs - Ideal for LED Strips, Motors, and Speakers by Brian Rivera

"JOVNO 4V-12V 10A 120W Adjustable AC/DC Adapter" is an adjustable DC power adapter. What I liked: - It comes with many adapters. What I didn't like: - The product tile says "4V-12V" but the spec says "3V-12V". You are inconsistent. The lowest voltage I could get was 4.04V. It's supposed to deliver 10A at 12V. However, when I tested it with a load tester, the voltage started to drop with increasing output current. At 5A the measured voltage was only 11.5V even though the reading was 12.0V. At 9A the measured voltage was only 11.1V even though the reading was 12.0V. If I increase the current to 10A, the block turns off. (see videos).
