DC Voltage Regulator Buck Converter DC 12V/24V To DC 5V 3A 15W Step Down Reducer

The die-cast aluminum alloy case feels incredibly durable. It's fully sealed, so I have no worries about it in a dusty or wet environment.

Used this on a 48 volt Electric Gator, (like a golf cart) to step down the 48 volts to 12 and run an actuator to tip the dump box (factory was a manual dump). so far so good, working as it should, output is 12ish volts which is good.

This is working well to regulate power to a mini-pc installed in my RV. I found the PC is too sensitive to handle 13-14V or ripple from the RV house batteries, so this solves that and it's been stable since I installed it!

I used this to step down a 20V Craftsman drill battery to 12V for some LED's I am running on a mini bike. Super easy to use if you know how to wire low voltage, if you do not, then just youtube it, there are plenty videos. I did not experience any issues with the polarity being reversed or incorrect.

I added this to my VW camper van so the mouse/rodent blocker would continue to function when I stored it with the battery tender attached. They are designed to only function when the battery voltage drops (vehicle not running). With the battery tender the voltage does not drop and the rodent scarecrow stops working.
This fixes that issue.
Very pleased.

I asked to connect a 48v 15amp battery to power some 12v turn signals and it worked perfectly, it didn't blow any LEDs and it continues to work perfectly.

I got a free ego back pack blower, too heavy for me, but 2x 48vdc 5ah li batteries & 2x chargers. Wanted to make a portable power kit, flexible for making 12vdc from 48vdc and also120vac from the 48vdc or plug in to my car 12vdc. This review is for 3 items: Cllena DC 40V-90V to 12V Converter Voltage Regulator Reducer, 12V/24V Fixed Thread Cigarette Lighter Socket & 300W Power Inverter 12v to 110v, Car Plug in Adapter with PD 27w USB-C and QC 18w USB-A, Car Converter to Outlet Plug, Red. I like the way it all turned out.

I am using this between a 100W solar panel that puts out 17-18V in full sun, and this regulator puts out a nice 12.6-12.8V that I then run to a 12V vehicle fan to exhaust heat out of my shop when it is sunny out. In the photo, you can see the regulator sharing the solar input with a charge controller. I went with this regulator so I could run the fan from the solar with no batteries attached.
