Review: Great power supply, cheap - Good output regulation, worked well for my application. I'd recommend individual downstream filtering (inductor & cap) if you are powering multiple devices where one or more is logic and another is noisy like servos, etc. But, I recommend this for ANY supply, so there's that :) BTW, I have *no idea* why desertcart asked me to rate this supply's "Warmth, Sheerness & Thickness"... There is just no accounting for some things lol
Review: Super Reliable - First bought this back in November of 2020 to step down 12V to 5V for a dash cam in a TC vehicle. After heavy use and extreme temperature changes every season, it's still in-service today (3/31/25). Highly recommend. I'm now purchasing another for a project using mostly 12V, it will step down to 5V to power some Arduino-controlled relays.

### ⭐⭐⭐⭐⭐ Hasn't failed me yet near max load, and with abuse!
*by B***. on 4 March 2021*

I must say I am quite impressed with these things. They are very efficient (little to no heat) and have a very stable voltage even with variable and high current. I have the 5v 15A version and am pulling ~13 A from it max right now with no voltage drops from the regulator. And although its only been a few months, I am very impressed. I have given these things more than enough reason to go out on me in this short time, yet they not only continue to work, seemingly unharmed, but even saved everything downstream from them. So what did I do? I used the same type of cable for both my 5v and 20v runs. I....managed to mistakenly plug in 1 end of a 5v light strand into the 20v wire, while the other end was plugged into the 5v. Thus feeding my lights and this regulator's 5v line with 20v. Only the short 1m strip of light between the 20v v+ and 5v+ was harmed, the other 20 meters which were connected to it in the other direction were fine, and didn't even react to the mistake (the 1m I killed went full white due to overvolt). Actually, the last 5 lights of that 1m still work fine (color changing and all), so I think the regulator managed to successfully sink the voltage down to near the 5.24V it normally operates at. I probably hurt their lifetime, but this thing and 100$ worth of lights that should have been instantly fried are still working like a champ! (And I really deserved to have everything fried. I plugged in my miss-wired devices 3 times trying to diagnose the issue. And the last time I removed the fuse I had on the 20v+ and let it run for 5 seconds) If you do notice a voltage drop, ensure it is not due to incorrect wire size by measuring voltage at the regulator. If the regulator is not supplying a steady voltage, you may need to check your power source. Even if your psu is rated for a higher voltage and current than you should need, it might not actually provides both at the same time. If your 20v supply drops to 6v when pulling high current there isn't anything this thing can do. And to any other amateurs considering using multiple of these to power a long light strip, be sure not to connect VCC of your lights to multiple regulators/power supplies. You can plug everything in like normal, but cut the VCC half way between the 2 regulators or power supplies. This will ensure each regulator is actually powering the lights their intended to, and ensures that the some devices will power off if a power supply or regulator dies instead of overworking other power sources. And, additionally, largely reduces the risk from an accidental overvolt.
