Very helpful! - Power Converter

Simplifies your life by eliminating the need to travel with too many power supplies and tangled cords. It's nice to offer something to a guest who forgot the correct charging cable.

Pros
  • Excellent value for money
Cons
  • No breaker

It can't handle 12V. It cannot be supplied with 10A.

"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

Pros
  • Easy Installation
Cons
  • Negative Impression

Looks great in power accessories

Build quality is acceptable for a mid-range band. Comes with an impressive collection of different tips for different devices. The built-in display is relatively accurate. The one I got didn't go to 3 volts or 12 volts. The potentiometer that selects the voltage has a hard click to turn the unit off and no other detents. You twist it until you reach the desired tension. Looks like something that could work as a gap closer in a pinch, but I'm not sure if I'll be using it for long periods of time

Pros
  • Rugged construction
Cons
  • Available in black only

Machine delivery OK for low precision work (see details). Conditionally recommended

I bought an adjustable AC/DC adapter JOVNO 4V-12V 10A 120W as an additional power source for my bank. I've found that I often need multiple voltages at once and don't always have enough buck converters for what I need. I started using JOVNO with some 12v WS2815s and then some generic 5050 RGBWWs. The voltage regulation is quite subtle and seems stable even at the higher end of the power output scale. The display shows a high voltage (about 0.2V), but it seems to be fairly stable regardless of…

Pros
  • GOLS certified
Cons
  • New competitors appeared

Poor performance or poor quality control - probably both

This power supply is at least 4 volts, not three as advertised (yes, even under load). The output current of the PSU at 12V is 0.5A. The knob for adjusting the voltage is actually quite easy to use (some variable PSUs are so sensitive that they cannot be properly adjusted). The actual voltage measured from several meters is approximately 0.2V lower than that shown on the display. The dial used to select the voltage also acts as an on/off switch, with the "off" position being fully…

Pros
  • Easy to read control panel
Cons
  • So-so
