I have been using this for over a year in an outdoor application where I am powering a 12 V security light with a solar panel and battery. It works great.

Specifications were what I needed but I was concerned about previous reviews complaining that this unit doesn't properly boost and that input voltage must be 13V or higher.I tested with a 6 ohm load across a range of voltages from 9V to 32V. Output remained constant at 12.65V - exactly as represented.Meets or exceeds specifications - 5 stars.

Had an issue where when my car was running it would jump from 12-14v because of the alternator and caused my lights to do weird things, this sopved the issue

The unit was used to stabilise a car 12V input (can vary between 12.6 and 14.5V with alternator charging battery) to provide a consistent 12V nominal output to power accessory electronics. It worked perfectly for about five years but then failed with no output. In checking other reviews, I suspect that operation around the change from buck mode to boost mode (eg. about 12.6V input) is not capable of providing much more than 1A at a 12V nominal output, and this stresses the internal components. In tear-down and review, there is also insignificant input surge protection, but the main culprit is that the converter use the LM3481 which is capable of buck, SEPIC or flyback operation. With SEPIC providing the boost function, the output current is dependent on a series capacitor and currently is inherently limited. I will buy a better quality item as a replacement, and this will cost a significantly more.

I purchased a Lithium Ion Power Bank to power my 12vDC CPAP device while off-grid camping. Unfortunately the power bank produces over 16v and the CPAP device is "smart" enough to protect itself and refuses to run on that voltage. Putting the output of the powerbank through this device gives a steady voltage of about 12.3v...basically ideal.

I modified an electric childrens vehicle and added many automotive grade LED lights. I found that the lights would dim and flicker when the child would press the accelerator pedal. This module allowed a consistent 12V output to the lights irrespective of the load on the source battery, and resulted in no change in light brightness whatsoever. Fantastic product which appears to be well made.

I bought this because the 12 volt output on my solar generator is not regulated. As the power in the lithium ion battery decreases, so does the voltage to the 12 volt cigarette plug. My 12 volt compressor fridge has a battery protect feature that shuts it down as soon as the input voltage hits 12.2 volts. My solar generator battery can safely be discharged down to 11.5 volts, which is several hours or even a day more of potential runtime before recharging.Using my variable DC power supply, I tested the output of this regulator from 35.5 volts all the way down to 2.5 volts and found that it puts out a constant 12.3 volts at any of these input voltages.One issue is that it will draw a small amount of current even when it is not under load. If the input voltage is 12.3 volts, it draws only 9 mW of power with no load. The more that you vary the input voltage either lower OR HIGHER than 12.3 volts, the more current the regulator will sip when under a no load condition.There appears to be no shut-off voltage, so this will completely drain and ruin your battery if left unmonitored. Fortunately, my solar generator will cut-off the 12-volt output to protect it's internal battery when the voltage drops below 11.5 volts, but this might not be the case for everyone.

I usted with a Óptima Yellowtop to provide 12 VDC to my Network to pass through any power fail.That cost les that a UPS for a better result.

When dry camping on just RV cabin batteries, our Jensen Stereo/DVD player would power cycle off then on every time the furnace would kick on. The RV voltage would drop just a little due to the starting power surge of the furnace. This inexpensive DC voltage stabilizer solved the problem. Wiring diagram is on back of the regulator. Just install inline with wire nuts, two input, two output. Gives off very little residual heat and minimal ghost current draw. Love it!
