## Customer Reviews

### ⭐⭐⭐⭐⭐ They work great!
*by C***. on August 2, 2024*

These voltage reducers are being used to allow me to use a 12v adapter with my coleman inflatable mattresses. The idea being to skip the use of 4 D batteries (weight). The modification allows me to use my Jackery to power and inflate the mattresses when camping while avoiding the issues with D batteries, both the weight and chance of them giving up the ghost at the wrong time, ie. while camping....Excellent value and looking forward to many camping trips.

### ⭐⭐⭐⭐⭐ Great voltage converter
*by J***N on November 15, 2024*

I was working on a project that used a 12 VDC power supple but I added a component that needed 6 VDC. I found the voltage converter and decided to try it. It just what I needed and worked the 6 VDC device without any problems.

### ⭐⭐⭐⭐ perfect for custom car wiring
*by R***K on March 5, 2023*

I used this to custom wire for my e90 a wireless charger. I had tapped into a 12v power supply and needed to step it down so the wireless charger could use it. This worked perfectly on my install.
