    Customers say

    Customers like the performance, quality and adjustability of the power converter. For example, they mention it works well, is reliable and stable. Some appreciate the variable voltage regulator and the value for money. That said, opinions are mixed on the heat sink and current.

    AI-generated from the text of customer reviews

    91 customers mention84 positive7 negative

    Customers are satisfied with the performance of the power converter. They mention that it works well, it functions flawlessly in sub-zero weather, and it's a great product. Some say that it'll work without getting hot.

    "...the 50k potentiometer with a digital potentiometer (8 bit) and it works beautifully, giving 100mV step resolution in my application...." Read more

    "Excellent product and probably the best we've had so far.Added a cooling fan and putting it to the test! So far readings are great...." Read more

    "At first the regulator worked like a dream. Needed to set the output voltage to 12 exact, and that's what I got...." Read more

    "This supply worked much better than expected. I was prepared to upgrade all the capacitors but so far no issues...." Read more

    52 customers mention38 positive14 negative

    Customers like the quality of the power converter. They mention it's reliable, easy to use, and does the step down conversion very well. Some say that it'll last a long time with very little problems. Overall, customers are satisfied with the quality and functionality of the product.

    "...It seems very well constructed, and it is a wonder of Chinese manufacturing that it can be sold for this low price...." Read more

    "...(so strong and powerful)..." Read more

    "...The input/output ports are a little flimsy, however if your not constantly loosing and tightening, your fine." Read more

    "who doesn't love nice control over voltage. The unit is small and nicely made, the adjustment pot doesn't have the resolution of a twenty turn pot,..." Read more

    21 customers mention15 positive6 negative

    Customers like the adjustability of the power converter. They mention that it's an excellent variable voltage regulator, that needs a larger input/output connection, and that the output voltage was well-regulated. Some say that the tuning is sensitive, and the input voltage varies greatly.

    "...Testing was performed with 14.2 V input. Output voltage was well-regulated, better than 0.1% for 0-3 A loads...." Read more

    "All 4 of the regulators I received work well and adjusted easily...." Read more

    "I received a replacement and its output voltage could not be adjusted either. I have another that i bought a year ago and it works great...." Read more

    "...The input voltage varies greatly. 17-33 volts depending on how fast I pedal but the output remains a steady 14...." Read more

    16 customers mention16 positive0 negative

    Customers appreciate the value of the power converter. They say it is well worth the price.

    "...They work beautifully and it's DEFINITELY worth the cost not to have to worry about cobbling one together myself...." Read more

    "...That being said, the price on this is not unreasonable so it might be worth the risk if you're on a budget." Read more

    "...Other then that, this was well worth the price." Read more

    "The quality of the circuit board and components are worth the price, it actually had a printed solder post to install a fan if needed in addition to..." Read more

    11 customers mention8 positive3 negative

    Customers like the size of the power converter. They mention it's compact, easy to use, and reliable. Some say that it'll work in a +200°C test environment. Overall, most are satisfied with the size and functionality of the product.

    "Brilliant compact unit for lowering the voltage.It doesn't have to be just for a car...." Read more

    "who doesn't love nice control over voltage. The unit is small and nicely made, the adjustment pot doesn't have the resolution of a twenty turn pot,..." Read more

    "...an important thing to note is this is pretty small and you'll need some tiny flathead and phillips drivers to tighten the connector screws and..." Read more

    "This converter work just as it is supposed to, it is compact and doesnt put off much heat. I purchased 3 units...." Read more

    10 customers mention10 positive0 negative

    Customers are satisfied with the stability of the power converter. They mention that it holds stable voltage for the most part, regulates perfectly down to 12 volts dc, and holds the voltage well. Customers also appreciate the large and well-attached heat sinks.

    "...The wires are even held in place firmly by the screws and the voltage hasn't moved with all the jumps, bumpy off road riding etc...." Read more

    "...Voltage holds stable for the most part...." Read more

    "...17-33 volts depending on how fast I pedal but the output remains a steady 14. It is also nice that it has circuitry for a fan for long term usage...." Read more

    "held voltage well. took a good many turns to find the adjustment" Read more

    19 customers mention13 positive6 negative

    Customers are mixed about the heat sink. Some mention that it has good heat sinking, runs cool, and doesn't warm up very much. However, others say that one of the heatsinks got very hot and within a few minutes the magic smoke was there.

    "...I can say that the module hardly gets warm under these conditions. Good heat sinking and decent efficiency from the on-board switcher...." Read more

    "...It doesn't get hot or even warm at the bottom of my bike, probably because of the airflow and possibly the extra heat sink I added...." Read more

    "...the heatsink gets up to 140F so yes it is HOT. Im not using it to charge a battery but only to supply power" Read more

    "...Heating was minimal at 12V, 3A output...." Read more

    10 customers mention3 positive7 negative

    Customers are mixed about the current of the power converter. Some mention that it runs continuously all day and maintains output at 14, while others say that it does not supply anywhere near the rated current and generates a lot of noise. Some say that the power is a little dirty and the regulator was only taking in less than one volt.

    "...the starting battery off the generator 12 volt output the voltage gets to high and i dont want to burn the battery up...." Read more

    "...Almost no current was running through the input. I tested the output to see if anything was going through.. my multimeter marked zero...." Read more

    "...to a 100w solar panel (12v rated but output 19v) and it run continuously all day (so strong and powerful) until the sun went down where the fan just..." Read more

    "It arrived in working condition.However, it does not supply anywhere near the rated current, and generates a LOT of noise...." Read more

    Works great in harsh envioronments.
    I attached this at the bottom of my electric dirt bike to constantly power an 8 amp draw, It takes a beating at the bottom of my bike only attached with tie wraps and keeps functioning 100%. The wires are even held in place firmly by the screws and the voltage hasn't moved with all the jumps, bumpy off road riding etc.I needed to cover the top of it to prevent lots of dirt and water from spraying directly into the unit from my front tire, so I decided to thermal epoxy an extra heat sink I had laying around on top of the heat sinks already on the unit. I ordered artic alumina thermal adhesive to easily join them together.http://www.amazon.com/gp/product/B0009IQ1BU?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00The unit will get hot without airflow at higher amps, like 8+, like if sitting out on a table without good airflow. It doesn't get hot or even warm at the bottom of my bike, probably because of the airflow and possibly the extra heat sink I added.If you plan on really pushing this thing at high amps then I would epoxy on an extra heat sink like recommended in the description. But of course test it out first and see how hot it gets to see what you will need.
