Universal Power Supply 3V~24V 3A 72W Adjustable Variable 3V 5V 9V 12V 18V 20V 24V AC/DC Adapter Charger, 100V-240V AC to DC Converter with 14 Tips, Polarity Converter and 4-Way Power Splitter Cable

So far so good. I guess I didn't realize the control know was gradual... Thought it had set voltages. But, it's OK. Seems sturdy and lots of accessories. I did add to this kit a cigar lighter adapter.

I bought this to use on my weed eater. Because I lost my original plug. It worked perfect. Charged the battery like I needed. And it was very simple to use.

Provided connections for multiple devices that cords had broken and worked great

It's a bit tricky to set the voltage and it does fluctuate a bit over the time your device charges, so better to set it around a couple tenths lower in case it fluctuates higher. Lots of different connectors, so fits most devices and saves plenty of time not having to track down those adaptors you've lost track of over time and a great price.

It is an excellent product that delivers what it promises,

Solved my problem of finding difficult to find replacement power supplies. Would buy again.

I am more or less happy with this set, but what really upsets me is that they DO NOT PROVIDE A CASE TO KEEP ALL THE PIECES TOGETHER!!! It doesn't have to be a fancy thing, a cheap soft-sided zipper case or a clear plastic box that clips shut. This is not my first set of these and every darn time I get them, part of it disappear/gets misplaced so I have heads with no electtrical part or electrical part with no heads. Can't y'all just package this with a case, please!?!

Reasonable price. Performed well for my purposes. I have used it to test lightbulbs and other playfield items on my pinball machines which use a variety of voltages.
