- In this video, I present an overview of the ZK-5KX buck and boost converter. Its power is slightly more than 80 watts. It is very compact and has many features that are required from an LBP. I will clearly show you how to use the device and how to use its functions.
Shop on Aliexpress where I bought the ZK-5KX converter:
alii.pub/6i4v2a
There are also other versions of this converter
ZK-4KX --- 50 watts
Input voltage: 5.0-30V
Output voltage: 0.5-30V
Maximum current 4 A

Thanks for the excellent description of this device! The instructions on the Amazon page aren't very clear, your video showed it much better.
Thank you for watching. I'm glad I could help you.
On CZcams, It's one of the best videos on the subject 🙂
Thanks frend!
A masterpiece !! ⭐⭐⭐⭐⭐
Thank you
ótima explicação.
Obrigado!
Conteúdo sensacional
Muito obrigado
If you set playback speed to 2x it is still realy slow video :-D
Hi, I have a problem, the red DC LED always stays on even if I don't connect anything, how can I solve it?
Hello my friend, a question, how to charge a laptop batery with this device? I tried, I connect it to a 12v battery, then I regulate the voltage to 19.5 which is the same as my laptop charger, but my laptop does not charge and I don't know why it could be
Hello. It is very strange. If the laptop power supply has only two contacts (only + and -), then everything should work. This is, of course, if charging the laptop is simple.
Good job 👍👍👍
Thanks !
I plan to use this unit as battery charger. Does it have reverse current protection on its output in case input power source stops?
Or do we have to install a blocking diode on ZK-5KX output terminals to protect the unit?
Yes, you may need a diode. There is a resistor inside to discharge the capacitor at the output. It will drain the battery. But if you install a diode, the device will not be able to display the battery voltage.
Your timely reply is much appreciated!
Based on your response, I reviewed your authoritative video and noticed that you connected the buck boost unit with no input power (off state) to a Li Ion battery 14:37 with no destructive effects on the ZK 5KX.
That was the answer I was looking. Datasheets claim that the output end has anti-reverse current protection, no need for anti-backflow diode. And it's true 😉
As for the capacitor-discharge resistor draining the battery, it can be easily taken care of. Looking forward to more of your well illustrated videos. Subscribed to your channel 👌 Thank you!
Thank you!
I have got one of these units. The CC does not seem to be working as expected.Suppose I set the voltage to 5V and a max current of 100mA, if I short the output or put a sufficient load ,the output current stays at 60mA.Also the CC LED does not light up.Any suggestions ?? Everything else works as expected.
Yes, there is something wrong with him, but I can’t advise . I checked with myself. I also set it to 5 volts and a current of 100mA. During a short circuit, the current is 100mA and does not change.
@@Den_Electro_channel Yes I verified it, unit has problem.
I use CC on mine for battery charging- it works fine but can be adjusted once. If I adjust it more, then it will give out max current instead-and sometimes will shut down due to overpower. My solution is to switch whole powersupply off when I want other current. Maybe this clitch doesnt happen all the time but I've become used to switching it off when different batteries are connected.
hey man hope you can help me.. I've followed your video but my unit says 0vp on the output
parts need to be disassembled and tested. It's so hard to say what's broken in him
Sir, I use it for my 12v 15ah lithium ion battery charging..
There is a problem that after some time it got error message, may be because of constant current....what should I do
what is the name of the error?
@@Den_Electro_channel I don't know sir, may be it off, I don't know is it because of heat or Battery BMS?
@@arpitsingh5152 it's so hard to advise anything
Can it endure 5amps for long period of time?
I charge the battery for 15 hours. The current was 5 amps. But then he did not have a body.
Now in a small case it heats up more. But for a long time did not turn on.
What is the max imput watts? i want to use a solar panel
if the output is approximately 80W, then the input is approximately 120W.
@@Den_Electro_channel Excelent thank you, greetings from Guadalajara México
and greetings to you from Kazakhstan!
Bu cihazları neden anahtarlamalı yapmıyorlar güçlü bir mosfet ve fan yeterli olacaktır bu cihazlar çok hasas hemen çöp olabilir başarılar diliyorum
