This works great to check voltage on little gadgets and if you building a little product and want variable voltages.

Last year when taking down Christmas decorations the power cord on 1 of 2 strings of indoor Icicle lights was cut in half. As this Christmas approached I began looking for a replacement adapter cord, going to both hardware and electrical supply stores. I discovered there are multiple adapter sizes and this string of lights was not a universal size. This Power source has 6 voltage settings and there are 12 different sized plug in adapter cords. This is a universal "tool" that will be in the household "tool kit" for decades

Overall performance and application is good. The only thing I want to give emphasis is the lowest voltage. The description and label says 3v. But the actual out at 3V label is 5V

Extremely versatile, high current, infinitely variable voltage from 3V to 24V with easy-to-read display. The ability to reverse polarity for non-standard DC jacks is priceless. Dependable.

Este producto no cumple con lo que prometía. Según las especificaciones, se indica que soporta 24 voltios, pero cuando intento conectar un dispositivo que requiere esta cantidad de voltaje, el aparato no carga la batería en absoluto. Esto fue una gran decepción, ya que confié en las especificaciones del producto para realizar la compra. Después de varias pruebas y ajustes, sigo teniendo el mismo problema, lo que me hace dudar de la calidad y fiabilidad del producto. No cumplió con mis expectativas y me siento bastante frustrado, ya que esperaba que funcionara correctamente. Definitivamente no es lo que esperaba por el precio que pagué.

I have a zero gravity chair and moved to another state. The power source got separated and after 3 weeks looking for it, I ordered this product with the many “ends” insuring I would have the right connection. It worked and I’m so happy to have my chair working perfectly. Arrived before the due date. Packaged well . Great value .

Does its job and great value!

I had lost a power unit for a standing desk, I didn’t know the configuration of the unit. I bought this, adjusted the dial and tried powering the desk, which did the trick. Comes with a set of adapter which are very useful and can be repurposed for small electronics you want to test out.

Lo uso para cagar varios montables por que la función de cambio de voltaje me permite solo tener un cargador

Funciona muy bien, uso para una cama para levantar espalda y pies, que normalmente tiene una fuenta 220V /24V de europa

No es una super calidad, pero cumple con su función

Excelente opción para cuando no encuentras el cargador original de tu aparato electrónico. Muy recomendable

Que es muy fácil su instalación y uso.
