Powerful Voltage Regulator for DIY Auto Enthusiasts

As a hesitant DIY auto enthusiast, I was a bit nervous about using this device but I found it to be amazing! As a result of using this product, I found that the voltage regulator was powerful and had a constant flow of current that kept my car battery charged. It was easy to install and I will definitely buy this product again. The only con is that it may not work for every type of car, but it's worth a try!

Pros
  • Powerful and constant flow of current keeps battery charged
Cons
  • May not work for every type of car

Supplied without documentation

I haven't connected it yet so I can't confirm it works. It comes without documentation. I was hoping the documentation would be more detailed than Revain's description. First of all I can say that electrolytic capacitors are rated for the same voltage as the maximum voltage of the device, which is a very poor design criterion. Otherwise the build quality looks good. After connecting and testing I will write another review.

Pros
  • Input voltage: 7-40V
Cons
  • Nothing

only designed for 5A (overrated), CC mode somewhat imprecise; mediocre build quality; The rest is pretty decent; "good enough "

Summary: At $13 this thing is a pretty good deal despite the problems. I just expected it to work and not to the advertised specs. So far it does a pretty good job of powering the XHP70 LED which is why I bought it. Below I have listed all the problems you may encounter. It's not the best design for an LED driver, although to be honest it probably wasn't designed with that in mind. CC mode seems rather secondary, don't expect exact CC mode. Issues encountered out of the box: * This buck…

Pros
  • Applications: High power constant current LED drivers, rechargeable lithium batteries (including ferroelectrics), charging 4V, 6V, 12V, 14V, 24V V Batteries, Nickel Cadmium Nickel Metal Hydride (Battery) Battery Charging, Solar Panels, Wind Turbine Drop Regulator
Cons
  • High Price
