DC Converter 24V to 12V 5A 60W, Voltage Converter Step Up DC Power Adapter Waterproof Heavy Duty Transformer for Car Truck Vehicle Boat Motor Solar System

Works great stepping down my 20v dewalt batteries to 12 v.

Works great, as advertised.

This was a perfect component for my son's school robotic project where we had to reduce our voltage so that we could run a motor component that required a smaller voltage than the main battery. It was very stable and worked well without any issues.

This review is ONLY for the 24V to 12V, 60W version of this product. I bought this product to convert the output of a 20V (nominal, it actually goes down to 16V) cordless power tool battery to regulated 12VDC for powering a pair of 12V LED fog lights that I planned to mount on my snowblower as 'headlights'. My application was going to run at just under 30W, so THIS product's 60W rating meant that I would hardly be stressing it. I found that the output voltage could have been adjusted a bit more accurately; it put out 11.5V instead of 12V, but this is not user-adjustable, and was not critical anyway. My only complain with this product is the poor conceived mounting scheme. The 'base' of the converter has two mounting tabs, each with a "U" shaped slot, which is sized to fit a #8 screw (or similar metric size). The problem is, that right above each slot are two protruding shapes where the wiring comes out. I was not able to get the screw heads past these protuberances, so I tried coming up from underneath, which then required me fit a #8 nut on the flange, but two reinforcing gussets prevented those nuts from fitting (but a typical #8 screw head WOULD fit between the gussets). Perhaps a small pop-rivet might have worked but I don't think the come in sizes that are small enough. I ended up using much smaller size screws and nuts, along with flat washers, a bit kludgy.

Used this for a nilight setup copied from a YouTube video. Works great and there isn’t any power surges or anything out of the ordinary. Would use again should the need arise.

Got this to add a 12V 5A output jack to my 3D printer with an inbuilt 24V power supply. Driving an added 12V enclosure fan and 12V Sonic Pad (a small tablet computer) off of it. I estimated I needed about 3A, and this would give me that with room to spare. Wired this up with ferrules straight off the power supply to a case mounted barrel plug port, and been working great.

So I bought one of these to power a screen for my 3d printer. The power supply was 24v, the screen was 12v. The first one did not work. Upon testing it with a meter, it only reported 5v. I sent it back and got another one. With this one I used some quick twist caps to test it, again it only gave me 5v. Unfortunately, I don't have another 24v source to test it with. But that source runs my printer just fine, and it has been tested with two other dc to dc converters. One is a 5v for the raspberry pi. The other is actually a 12v that I've been using temporarily to power the screen. I wanted to replace it because that converter is quite large. It's also a 20amp for a 3amp screen. Maybe for some weird reason my psu just isn't compatible with this converter? I have no idea why that could even happen. But for reference, that unit is an LRS-350-24. I don't think the part was mislabeled, their 8-40v to 5v converters look entirely different. So, all I really know is that two of them did not work for me. I didn't take another chance with a third. I'm just going to buy a different brand.

I used this for my ice fishing electronics. You can buy an adaptor for your 18-20v drill battery. This will drop the voltage to 12v to run most common fishing electronics. One less battery to be lugging around on the ice is nice. This supplied enough power to run my garmin striker 4, charge my phone and run all my shanty lights without even getting the least bit warm.
