Item works as advertised. The trim screw allows you to adjust in millivolt increments. There is some noise, which is to be expected from a buck power supply. It's easily eliminated by a 47uf capacitor. The trim screw is located on the bottom, making it inaccessible after installation. Which, frankly, I prefer - set it and forget it. Some people took off a star because of this. C'mon people... use standoffs to mount it upside down, or drill a hole on the mounting plate. I paired this with a Bandc USB dual outlet socket to be able to charge my cell phone off my Ryobi One+ 18v Lipo batteries. Being a switching power supply means it won't waste power. (Some dissipation is bound to occur.)

Note the description says, "please ensure that the input voltage is higher than the output 3V", by which I assume they mean that the input voltage must be at least 3V higher than the output. Nonetheless, I'm using it to ensure that a "12 volt" battery system actually delivers 12 volts and not 13.8 volts, as some of my electronics are sensitive to over voltage. I would say the input voltage must be at least 2V higher than the output. So you can't use this to convert 13V to 12V. But you could use this to convert 14V to 12V.

The adjustment screw is on the bottom, and I can understand why some would ding this product for its placement. But I like it where it is, because it means that when I mount the device, no one can easily mess with the screw and change its setting. Frankly, if you need to make adjustments often enough that you would prefer the screw on top, then you probably want something like an adjustable power supply with a nice large knob and a voltage display.

I used this to direct wire my on board dash camera that needs 5VDC, (this is the same as USB powered devices) the original power cord was meant to be plugged into the cigarette lighter plug and was too short to conceal. I supplied 10-14 VDC and measured output at a steady 5.16 VDC. It is roughly about the size of a 9 volt battery. Bought two!

Used one of these regulators, an old Black and Decker inverter and a broken Ryobi inflator to make a portable 12V/110v 100w power source from a Ryobi 18v one plus system. This regulator is perfect for what I was trying to build, I had multiple large LED work lights for tailgating and a cabin that I used to run off a portable battery automotive jumper box. It worked great but when the battery was dead we were out of commission until I recharged the power supply. Now I can run the 3 large lights (two DC if I use a splitter and one AC) for about 1.5 hours, then pop in a new battery when it's dead. This device made it really easy to build and adjust, and it is encased in a moisture proof housing... It has been running flawlessly for a few months now without any hiccups. Absolutely perfect product. Thanks DROK!!!!

I am using this to allow me to use a 30 W solar panel to directly run a small solar water pump (12V) for a DIY water heater.

The little pump draws such a small load that if I connect it directly to the panel the voltage stays about 22 V in full sun, which is too much for the 12 V pump motor.

I connected this before to cap the panel voltage at 12 V. At full sun the setting of the variable voltage output screw gave me about 10.3 V (down from 22V) and about 1 and 1/4 turns clockwise got it to 12.0 V exactly for the output voltage.

At the sun goes down, the panel voltage drops and eventually (of course) the voltage output from this device drops below 12V. When the sun is enough to have the panel over 12 V, this caps the output at 12 V or below and the pump works perfectly.

I do not know how long it may last, but out of the box it performs perfectly.

Great little supply. With 12VDC input, I loaded the output @ 1.5A for 30 minutes. The case didn't get warm and the output didn't drift. The grounds of input/output are common. The aluminum case is isolated. The unit is smaller than it looks @ 1 3/8" long, 2" with tabs" (34mm / 50mm). The aluminum case is a C-shaped extrusion with the circuitry encased/potted in black silicone. There are no adjustments. Overall, VERY pleased.

Probably more for tinkering than for production (or long-term hobbyist) deployment. On my unit, you can easily get to the output power, but the adjustment seems to get out of whack when the power is cut and then turned back on. You have to re-tune it after that, which makes it unreliable to use when power is not guaranteed to be constant. I bought it for the waterproof aspect and that is very good as rain and puddles have no affected it.. There are other models with built-in voltage displays and those are probably worth the extra couple of dollars, but I have not seen one that was also waterproof.

A great little voltage regulator at a great price. My 1953 Ford F100 has a newer 12V electrical system & I used this voltage regulator to provide the correct voltage to original equipment 6V gauges. The trimmer potentiometer has a very fine adjustment, set voltage to 7.50V, and the regulator maintains that exact voltage with battery only input or the engine running/alternator voltage input. Perfect ! !
