3V~24V 3A 72W Universal Power Supply 3V 5V 6V 9V 12V 15V 18V 20V 24V Adjustable Variable Switching AC/DC Adapter, 100V-240V AC to DC Converter with 14 Tips & Polarity Converter & Test Lead, 3 Prong

I can not believe how good of a deal this is for what is essentially an adjustable bench power supply! It comes with every connector you would ever need, including terminals for bare wires, and even alligator clips! I am using this for an analog slot car track powering over 60 feet of track at one single point and it performs amazing! I can turn up the voltage for the adults, and turn it down to help the kids keep the cars on the track, it’s perfect!

I use this to power a headunit in my garage and it works flawlessly. The unit can take up to 17 volts and this keeps it at 16 .6 continuously without falling. Comes with an array of different tip options. Don't sleep on this unit. It's a good one.

This power supply did not work out of the box. Tested it on different outlets, and tested the leads with a multi-meter and no voltage measured.

Bought this for my husband. He loves it.

Bogotá-Colombia, 23/Feb/2025Es una fuente de poder básica para actividades que no requieran alta precisión. El voltaje mostrado no es muy preciso; por tanto, recomiendo una de las siguientes opciones: 1)Ajústalo a un voltaje inferior al que necesites o 2)Confirma con un multímetro el valor requerido. Ten en cuenta el amperaje requerido por tu equipo no supere los 3A porque podrías quemar la fuente. Sus múltiples puntas, permiten la conexión a casi cualquier equipo. No debes usarlo en equipos o pruebas que requieran una alta precisión; deberás buscar algo más sofisticado y por tanto, más costoso. Recomendado

Does what it says. Doesnt have every size adapter but has most common sizes. Love the adjustability of the voltage. This allows using this for many different products. Very easy to use and performs perfectly for charging almost any device that requires this kind of charger.

works great as a replacement for many devices, you are sure to find the right adapter
