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

Great little device. I use it in an off-grid solar power system to provide a stable 12V regardless of the voltage coming from the panels. Works flawlessly.

Works great with a Bluetooth speaker on a golf cart. However, I need to install a switch to turn it off when not in use, it tends to drain the battery.

I have clocked the input voltage from 8 to 20 VDC at 0.5 VDC intervals with the installed programmable power supply at 0.5 second intervals. Constant 12V DC output. Worked cleaning the radio in an old HEi distribution truck.

Fixed low coil voltage during start up for classic Mopar 440 I bypassed the ballast resistor and installed this regulator to keep the coil voltage constant. Commissioning is simple and consistent from the moment of installation. I'll keep an eye out for durability issues. I measured an output voltage of 11.82 ± 0.02 with the motor on and off.

Installed on a gas golf cart. My Yahmaha truck puts out 16 volts while running, which shut down the 120 volt inverter I had connected. This device regulated the voltage up to 12 volts. Now the inverter works. I would like to have literature with him. The Revain description says 140 watts which is about 12 amps at 12 volts so I used a 15 amp fuse for protection. But the device doesn't list the power rating, so I'm hoping 140W is correct. I'll probably buy one for my pontoon too.

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…
