Car Voltage Stabilizer, DC 12V Regulator Surge Protector 144W Heavy Duty for Car Battery Auto Truck Vehicle Boat Motor Solar System Protection (DC 10-36V Input, DC 12V Output)

Works as intended. Easy-to-use. Can save your electronics from an over charging system. Using mine on a fishing boat.

Excellent

I would highly recommend this product for your mobile ham radio needs. It keeps the voltage above the radio's voltage threshold to the point that the radio does not reboot on starting the car, either manually or by AutoStart. I have purchased 2 of these products and installed in both my car and my wife's .

I used this to control the 12v power stream to my Knight Rider custom dashboard and micro computer in my Knight Rider car. The car tells me the battery voltage is 11.9 to 12 at all times. Nice and stable! If you're looking for a way to keep your electronics stable without fear of over current damage, this may be your device. Its small. Easy to wire up as long as you can read English and can see colors.

This unit worked great to regulate the voltage to my Maxxair fan I recently installed on my travel trailer, which is reportedly sensitive to voltage over 13v which is for me, anytime my solar panels are charging. I also picked this model because of the aluminum housing versus some the cheaper plastic ones I have seen reviews that they fail and melt. I most certainly DO NOT want to have to worry about a melting plastic regulator in the ceiling cavity of my wood framed travel trailer...

Item was rated to handle voltage regulation at 12 Volts at 10 amps but, failed to do so with only a 1 amp draw. The voltage started to tank down drastically. Waiting for refund, as I believe I was sent someone else's already returned Item. I thought it was strange to receive parcel almost 3 days earlier than was stated it would be before delivery. Now, I have to go elsewhere to find good product.

Works like a charm.
