Buck Volt regulator is Handy Gadget for under $10, Step Down LED Driver product review.

*Please Read. (SPECS below) Here is my quick set up and usage tips. One of my Freego, China Segways runs on 72 volts and have no stock lights. The others run on 36v, but do have their own lights.
I needed something quick and inexpensive to convert ½ of the 72 v battery of 36 volts to run 12 v LED Lights.
This Drok LM 2596 Buck Volt Regulator tells input voltage, output current, has a USB Charger, and works perfect. I do not typically read reviews when I do a project, so not to be biased. My findings are strictly my own. Sometimes I will read reviews after I make mine. In this case I did, and found one fellow said the case does not have the legs cut right. Okay, there are no instructions and the case is a puzzle. Each piece which is precision cut will only fit one way. So turning inside out, upside down, until you get it takes some patience. All complain there are no instructions, which is true, but if a person was going to use this, he would easily figure out from the picture and the printing of how to make it work. Hopefully my video will give you an insight of what you can do with this neat gadget that costs under $10.
DROK® LM2596 DC Buck Volt Regulator 36V to 24V 12V 5V 3.3V 3V Converters Constant Voltage & Current 5-36V to 1.25-32V 5A 75W

1. Use as an ordinary buck module with over current protection capabilities;
2. Use as a battery charger;
3. Use it as a constant current LED driver module.
Note:
1. If the module can not be adjusted, the output voltage is always equal to the input voltage." When you encounter this problem, please counterclockwise rotation of the potentiometer 10 laps or more, then you can adjust the output voltage. Because the factory default output voltage is 17V.
2.Module output terminal string has a current sampling resistor, there will be 0-0.2V voltage drop after connected to the load, it is a normal phenomenon.
3..If its output is more than 3A/35W, please enhance heat dissipation!

I really enjoyed your video. For those that didn't know that the USB voltage was the same as the output voltage, when working with these little gems, buy yourself an inexpensive digital multi-meter and always check the input and output voltage before connecting devices. This little inverter works great for USB. I feed the USB to a 5 port device so I can charge multiple devices simultaneously. The 5 Volt D.C. output IS regulated to the voltage to which it is set.

[@MatthewRobertHenry]

This was so helpful, thank you!

[@freequest]

WoW thats a great find!

[@BOKI797]

Dave Really another Great Video Thanks ! Dave B.

[@Nqrgaard]

What can you do with the second potentiometer. I also have two on my regulator, but I can't figure out what the second one is for

[@dnunez1985]

what happends if you shortcircuit the output, and then power up the module? It still regulates on cc? for example, set current at 2 amp, when you short the output, it got to show 2 amp. If yo unplug and plugin the dc-dc converter, it still regulates at 2 amps?

[@DickGibson]

That is seriously kool Have to get me one

[@RideWithAnthony]

on the strip light if you were to set it to more than 12 volts could you damage them? and also is there a way to make sure to set it to 12 volts so it wont mess up you strip lights?

[@coyote20030]

Quick question, do you have to press a switch to get it to output, or will it remember it's last state? (I have a smaller version that requires a button press to output) Thanks, Dave

[@TheJigglicious]

Will this power supply safely down convert them voltage from 50 volts down to their selected output voltages?

[@F6Hawk]

So is the max output of the USB 600 mA? Or is that adjustable as well? I'd like something that can push 2.5~3 A.

[@pollydor07]

THANKS . BOUGHT 1 FROM AMAZON , BANGGOOD , EBAY , ALIEXPRESS .

Can someone tell me where I could get one of these with the plastic case as well???

[@connormouse]

I have the same unit. Connected a 12.8v DC Battery (lipro) to the input and the M7 diode fried. I've replaced the diode with a 1n4007. Any idea as to why the M7 fried as I understand the voltage was well within the input specs? Help!!!! Thanks

[@Jcelkhouri]

Hi, nice video. Can you run led strips at 12v and reduce the amps to dim?

[@need4drift]

Very nice regulator. Can i use this to power up a 11.1v fpv system with a 4s lipo?

[@yanrpopoff2804]

will this work on an rc truck? it can handle 11.2v but the only batteys i have are 7.4v 2s and 14v 4s my esc max it will handle is 11v? or will the amp draw kill the board

[@MrOOSTUOO]

Very nice!~

[@samrenzryanreyes9740]

Hi sir. How can it work in piezo? It is possible to work in piezo? Thank you for the reponse.

[@Nqrgaard]

Hi How can I add a potentiometer to a buck boost converter (voltage regulator), so i have the possibility to set a min. 6 volt and max 12 volt and use the extra potentiometer to dimm the LED light from 6 (off) to 12 volt (full brightness). It is for video work, so i don't want flickering of the light

[@mepanousispanousis6784]

I need a adjustable current limiter/regulator . Ex . I want to change a battery but i want to be sure that the voltage will never go over 14 volts and the current will never be more than 0.5A for as long as it is hooked .Can this module do this ?

[@yelectric1893]

Hmm. Could this be used with a power mosfet to add switching to the output ? Could it be switched at 50 kHz or 1 mhz?

[@subsonicreviews1835]

Hi NightFlyyer, very helpful video, but this unit states it can charge Lipo and Life batteries . But how do you charge lipo without the balancing plug??? All lipos and life have to plugs. A balancing plug and the main plug

[@lasseelectronics8914]

Hi, I like your video and appreciated it very much. Thank you for your time making it, so others can learn. I have a question, form the figure you showed in the film, is it correct, that I can set the Amps too? because I need to compress 14,8V into 5V but, I need around 3 Amps - is it correct, that I can set it like that? Do you know the maximum Amp it can produce? 5? 10? thank you very much in advance, sincerely Lasse

[@UTKZ1]

Can somebody tell me where to get the transparent plastic box?

[@cmj20002]

I have the same module with a blue display and I have noticed that if you push and hold the right button the display will flash and you can adjust it up or down. Any idea as to what that adjustment is for. Perhaps accuracy of the volt meter in it?

[@frenchfry5675]

That is for setting the incoming voltage as far as I can tell. The pots dial the voltage available up or down.

[@LearnerCB246]

I have watch your video several time andI still cannot adjust the ouput to 6V and 4ah.

[@chrislapointe7861]

Can we powered it with more than 5amp

[@InfinityVision]

Can someone help? I have this Drok model. www.droking.com/75W-Power-Supply-Module-USB-Charger-DC-6-32V-to-1.25-32V-5A-Buck-Converter-Adjustable-Voltage-Regulator-DC-12V-24V-Adapter-Driver-Module-Dual-Display-Digital-Meter I use it to charge batteries and I can’t figure out what the current adjustment is used for. Doesn't the unit alter the current amps automatically based on the input voltage and lowered output voltage? Is this supposed to act like a cut-off switch you set when a voltage is reached on the charged battery?

[@francistembo650]

Would you be able to remember the maximum output current for the USB output?

[@NightFlyyer]

As it says in the specs :08, it is 5 amp Max. Thanks.

[@victorkustov]

Коротко и ясно. Спасибо.

[@locouk]

Can it work the other way, feed 12 volts in and step it up to 24 volts?

[@NightFlyyer]

Green Silver No.

[@hassnbasem2403]

Hello,Who can help me... I have this same device and the main 5-pole transistor has failed (burst) ... What is its name and number? To do a replacement, thank you

[@johnrugani9832]

How many amps can this handle? I'm looking to take 16.8 volts down to 12-13 volts but i need something that can handle 40 amps Do you know of anything?

[@NightFlyyer]

Not sure about that, but if you check Drokss website they may be able to help. www.droking.com

[@johnrugani9832]

NightFlyyer Thank You for your input, I will give that a try

[@WVRetreat]

As the input voltage goes down, so does the output voltage, right? This requires you readjust the voltage screw manually. The are some voltage regulators that will maintain constant voltage.

[@derrickharris3716]

Dave I notice when you had that battery plugged into the usb and you said it was charging, well it wasn't charging cause the blue light wasn't on only the green light was on. when the green light is in a solid state that means the battery is full and when the blue light is on without the green light being on, that means it's charging. Sorry not trying to be a a hole, just wanted to point that out. I have one.

[@kevinlivingston9563]

Derrick Harris yeah I noticed he said 0.6a/600ma but it was actually 0.06 which is only 60ma. so it maybe wasn’t high enough current to charge the battery?

[@PcandTech]

So i have Ac/Dc Psu witch gives 19v i could use this to turn it down to 12v ,but could it handle a lipo charger

[@NightFlyyer]

Hobbyandtech As long as you aren't charging more than 4.5 Amps according to the specs, or you'll need better cooling and a bigger heat sink. Good Question. Thanks.

[@PcandTech]

Awesome , would have to give it a test , for the price cant go wrong thanks

[@chrislapointe7861]

Hello guys, can I connect a 12v 9Amp battery to the input of this module?

[@HumbertoYi0878]

TheGamerBoy 12 volt battery is fine. Those 9 amps your referring to is probably the max draw the battery can handle, or more likely the amp hours. Amps aren’t pushed, they are pulled.

[@JoseGonzalez-ru3mt]

I bought the same unit at DX and I thought the usb output was always going to be a regulated 5v output regardless of what output you choose to have by adjusting it with the volt potentiometer. I set my output voltage to 9v and checked out of curiosity how many volts was coming out of the usb port. I was shocked to find out 9 volts were coming out on the usb port. Then I raised it to 12v and the same thing happen. So dont use the usb port for charging your cell phone unless you have it set to 5v on the output meter. In other words the usb port will output what ever voltage you select to be the output on the meter. It's not separate from the reading you get on the output.

[@pistiberez]

Yes ,USB ruined my tablet with 20V.

[@NightFlyyer]

I don't know. I never ran a cell phone with it. If it is working, I suppose it is fine, but mine burned up when my house burned down on 911 2016 and I don't have another to check. Sorry.

[@Jack-jl2vf]

@@NightFlyyer Sorry to hear that about your house, but it looks like it is working the way it is supposed to, so I am monitoring it carefully before I put it to use, I am using the phone as a scrolling sign board .

[@prakashspex]

I thought you adjust the voltage with the front right nob? why are you adjusting it with the screw? THX

[@NightFlyyer]

There are no knobs. At the beginning of the video, I show what each control does. There are 2 push button switches on the front. Pushing the one on the right changes readings. Push it to select voltage, then use the potentiometer screw on top left to adjust voltage. Push the button again and it changes reading to amps. Then use the right potentiometer screw to adjust amps.

[@prakashspex]

@@NightFlyyer Thank you for responding. I misunderstood. Where can I find a device like this, that has an adjustment KNOB, instead of a screw? Any information would be greatly appreciated, thank you so much

[@NightFlyyer]

@@prakashspex unlikely. A knob would be too easy to bump and so this keeps things stable.

[@prakashspex]

@@NightFlyyer could a knob be installed, I use it for a different application,thx

[@NightFlyyer]

@@prakashspex Not easy. You would have to find a larger potentiometer of the same value with a knob like a volume control and mount it externally. Good luck.

[@edgdeal76]

I have something similar. I connected it backwards and blew something inside. It's a step down box. 60v to 12.

[@NightFlyyer]

Yes backwards hookups are not good. What runs on 60 volts?

[@edgdeal76]

I have a 52v battery for an ebike. I'm pretty sure I blew something when I accidentally reversed the polarity into the step down box on. Would u happen to have an idea of what I may have blown? I'd like to repair it myself. I'm trying to learn about these things

[@NightFlyyer]

@@edgdeal76 Usually there is a diode to prevent wrong polarity hook ups. If you have too much voltage, the diode is always the thing that blows. It works like a 1 way fuse. Or, there may be an actual fuse that blew. Good luck.

Hi guys! I buy this module. it was great, but I wonder how it can display the voltage ? And how does it connect it? Thank you...!

[@zaprodk]

Wow, 6V USB - that's a shocker - I'm not sure that most equipment likes that!

[@NightFlyyer]

***** I can turn it down with the screw and also the amps.. 6v seems fine and I've been using it to charge my cell phone and charge batteries. So far so good.

[@zaprodk]

***** Eeeek! - You are a brave man! The most old-ish electronics can handle 5.5V MAXIMUM so putting 6V into a new device that runs 3.3V, 2.5V & 1.8V internally is indeed brave!

[@NightFlyyer]

***** I didn't buy it for the USB anyway, just to turn down my v to 12v. I used it for this demo just to prove to myself that it worked and it seems just like my Receivers for RC, all contain voltage regulators. Many wall wart USB chargers Ive seen put out more than 6 v. Thanks for the concern, for it may be justified, I dont know longevity yet, just a simple convertor cheap. LOL.
