I did not realize just how compact these little converters are. When I received it I was happily surprised. My intention was to use this to power a string of RGB LED's and an ESP32 board running Wled for our 5th Wheel Camper under belly lighting. The camper runs off 12v DC, so a conversion to 5 volt needed to happen. I could run an AC wall wart but then I could only run the lighting when we were on shore power, or the generator was running. Running off the batteries with this adapter I can run it all the time no issues.Being compact was a definite bonus from this unit. It is 1.5 x 3 x .6" This lets the box I have to install it in be smaller and easier to hide. It also makes adding on units or hiding them inside projects simple enough. I have a lot of 12V supplies around that I can now use for my 5v lighting.I ended up connecting this to the ESP32 and 3 strings of 50 RGB WS2811 12mm LED's. It had no issue at all. I ran a power injection to the end and it lit the led's with no fade or shadowing at all, even at 100% brightness on pure white. I did not have a change to test the over/under current/voltage features. Will try to do so in the future. I also haven't thrown a scope on it to see how clean of a conversion it really is. Will do so soon an report back.So it does exactly what it says it will do and works perfectly.

I've tested the dkplnt 50W DC 12V/24V to 5V 10A Buck Converter under a range of loads and conditions.Performance & Efficiency:In terms of raw performance, this converter delivers as promised. It reaches peak efficiencies up to 94% under light loads (1-2A output) and maintains around 90% under heavy loads (10A).Parasitic current draw measured at about 5 mA on 12V input and 4 mA on 24V.Input/Output Consistency:Across various scenarios—from light to heavy draw—the output voltage remained near the 5V target, showing minimal sag even under a full 10A load. It performed reliably with both 12V and 24V input sources, providing stable output for demanding electronics.Ripple & Noise:Ripple stayed modest at ~50 mV @ 180 kHz under moderate to heavy loads (>2 amps) but was slightly higher at lower loads (120–150 mV) with different lower frequencies depending on load which is fine.Thermal Behavior & Safety Features:Because the converter is compact and lightweight, it tends to run quite warm under continuous heavy loads. Mounting it to a heatsink or ensuring adequate ventilation is recommended to prevent overheating. Additionally, there appears to be a built-in overvoltage protection mechanism: if the output exceeds ~6V, the converter shuts down and does not restart until input power is cycled. This is a useful safety feature, though it might surprise users who are unaware of it.Conclusion:For $9.99, this is a high-efficiency, versatile buck converter well-suited to a wide range of low-voltage applications. Just be mindful of heat dissipation under high loads, and the output cutoff feature above 6V. It's an excellent value for hobbyists and professionals alike who need reliable 5V power.

I have a USB-powered LED strip that I am going to use on the music desk of my virtual pipe organ, to replace the antiquated fluorescent lamp and ballast. I ran across this converter and it's perfect for my needs.Shown in the photo is one (of two) of the 12 vdc, 50 amp power supplies in the organ console, powering the converter which in turn is powering the LED strip via a USB-C power-only connector. I certainly don't have a need for 10 amps at 5 volts but it's good to know that I will have no problem adding other 5 volt components in the future if the need arises.This will of course, be protected by an appropriately sized fuse once it's permanently installed; this setup was just to verify that it worked.In case anyone is curious, the organ console has 100 amps of 12 volts dc available because there are well over 200 solenoids which control the stop knobs and coupler tabs, and worst case, half of them must be energized simultaneously. For any of you that might be organists, this would occur if every stop knob is drawn and every coupler tab is engaged, and the general cancel piston is pressed. Hardly a normal registration, but nevertheless it still must work without blowing any fuses or overtaxing the power supplies.

First let's just say that this is not a perfect bug converter. It's good, but not great. However, at $9.99 when it was ordered, it's a very good deal.As another reviewer had done some testing in anticipation of use to power a Raspberry Pi in a 3D printer, and that is the same plan for this one, some preliminary testing needed to be done. That other reviewer had found that the power supply was not stiff and the output voltage dropped fairly linearly under load.A half ohm, 50 watt load resistor was used in combination with a lab bench supply set at 24.00VDC to load test this converter. Unfortunately, the resistor was inaccurate, and only 0.75 ohms, not 0.50. As a result it was only possible to load the buck converter to 7.6 amps.No-load voltage was 5.112 measured on a calibrated Fluke meter and, under load, it dropped to 5.000 volts at 7.6A. That's only a tenth of a volt drop at 7.6 amps, which is quite acceptable.The bench supply never exceeded 39 watts so the claim of 95% efficiency in spec sheets that were obtained, seems correct. There wasn't a huge drop off as the other reviewer experienced in their setup. It's possible that their bench supply was not perfectly controlled, but it's also equally possible that the voltage converter they tested was defective in some way.This one meets expectations and should have no problem powering the Raspberry Pi as planned. At a future point, should a true 0.5 ohm power resistor be obtained for a retest, updated information will be provided for 10 amp, 50 watt full load.
