Review on ⚡️ KNACRO Waterproof DC-DC Voltage Regulator: Convert 9V-23V to 12V, 12A- Stable Car Power Supply, Ideal for 144W Car Electronics by Ryo Flora

Revainrating 3 out of 5

Mainly functional product for power converters

This device converts unstable DC voltage into an excellent 12V DC voltage. This is exactly what I need for my car's needs. However, the voltage drop after switching off the supply voltage is quite slow. The electronics box I'm trying to power doesn't work very well at low voltage, so that "tail" is a bit problematic. Another big problem is that the mounting flange is almost impossible to use. There is practically no gap between the mounting holes and the edge of the device. I still haven't found the right screw configuration to keep this clean.

Pros
  • Trial period for one year
Cons
  • Not all suitable
