Review: Works like it should. - This works great to check voltage on little gadgets and if you building a little product and want variable voltages.
Review: Great Value: Quality & Versatility with 12 Sizes - 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

### ⭐⭐⭐⭐⭐ Great Value: Quality & Versatility with 12 Sizes

### ⭐⭐⭐⭐ Good to have and convenient to use
*by T***Y on June 1, 2021*

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
