## Customer Reviews

### ⭐⭐⭐⭐⭐ Great value item
*by J***H on December 12, 2025*

Works great for my slot car track

### ⭐⭐⭐⭐⭐ ​Great price and highly versatile!
*by S***S on January 4, 2026*

This kit includes a huge variety of plugs for almost any device. It’s perfect for hobbyists, though I do wish there was a way to lock the voltage setting to avoid unintended changes.

### ⭐⭐⭐⭐ Overall great with a fiddly dial.
*by K***S on August 9, 2025*

Very solid option for those needing something that can get up to 30-36-Volt range when most of these only top out at 30-Volt, worked well for a laptop and a vacuum battery no problems. Good assortment of connectors that will fit most things, you can always buy more attachments later to go with it as well. Works well once you get it dialed in but as is typical with many of these it is a bit of work to get it down to a exact voltage and will require some very fine tuning of the knob to get.
