120W Power Supply Adjustable DC 3V ~ 24V Variable Universal Switching AC/DC Adapter Minidodoca AC to DC Converter with LED Voltage Display and 16 Tips, for 3V to 24V Household Electronics - 5000mA Max

Works great

The reason I bought this was to power up an electric seat removed from a car for repair. This was the only one that had the alligator clip to power supply adapter which is what I needed. The other adapters were bonuses and I used one of them recently to test a different item. The power supply has worked perfectly and consistently. One thing that is not mentioned, the voltage adjustment knob does have an off position when you turn it all the way counterclockwise. The unit is more sturdy than the pictures tend to portray. All in all it's a great value for the money and it just plain works!

Works great, as advertised

Specs are a lie. It is really 3.5V-24V, it will not go below 3.5.Output wire is a pretty thin gauge so at 5A it has significant voltage drop, for 14.8V indicated, load will see about 14.1V.Voltage regulator potentiometer is regular 3/4 turn so adjustment is very sensitive and it's almost impossible to hit precise value.Overall I would not buy again especially at the price. For about 20 more you can get fully adjustable bench supply.

I use this product to mock up electronics that are aftermarket which I plan to install permanently in my vehicle. It lets me see how they would look/ function without having to attach them directly to my car's battery or make a wiring harness for them before I'm committed to installing them permanently

Me funcionó perfecto.
