IS THIS $2 Aliexpress Power Supply REALLY Laboratory Grade?

[@Hacktuber]

Dont forget to support the channel,please give a like,share and subscribe,thank you

[@wakeupcanadians]

no link to were to buy

[@sjsobol1]

Got to put a scope and a bigger load on it to really see if it is really laboratory grade.

[@Hacktuber]

Its a budget price psu,worth the money👍

[@Zerpentsa6598]

Silly billy. Lab grade at $15? What do you want to use it for? Spectroscopy? Yeah, $20 spectroscope. 😂

[@billyminefee3667]

I use this in a bench power supply, I made from an old computer power supply. works great.

[@Hacktuber]

Sounds like a good project👍

[@lohikarhu734]

I did a similar thing... I brought out the voltages of the PC supply to binding posts, and set them up so that I can put connections between voltages... 3.3 to 12, 5 to 12, and disconnected from output ground from the chassis ground, so that I can put two PC supplies in one box, and have+/-12, +/-5, 24V, 10V, and use two of the programmable supplies, in the same box, so that I have two independently adjustable supplies, to use as +/- supplies, separate sources, in series or parallel... So, I have fixed voltages of 12 V @ 16 A, +5 @ 20 A, +24 @ 8 A, and 2x adjustable supplies @4 A.

[@TheDradge]

I can't see this for any less than $6.31 on Aliexpress. Definitely not $2.

[@Pinball475]

Agree. On the video it shows it was a Choice "Welcome" deal.

[@philgray1023]

One of these videos was for a US$1.00 Bluetooth module. I bought 5 at A$0.94, that is US$0.56 each! They are brilliant. 3 days later they were A$1.12, so they went up 15%. Was that because I did a good review, because the Australian dollar went down or the Yuan went up? Special deals for new sign ups. Lots of variables here.

[@spehropefhany]

Thanks for the review. Some laboratories are worse than others- I had to solder in the bathroom of a US hotel because the lighting was too dim everywhere else (more like lavatory grade work). BTW, it's not a potentiometer- it's a (mechanical) rotary encoder with a switch.

[@Hacktuber]

You are correct,its not a pot,its a rotary encoder

[@RadioHist]

I have two of these in service. Use a 20 Volt Lithium battery (pack for power tools) to deliver up to 2.5 Amps to a tungsten load that must not go over 7 Volts. Works great and does not generate much RFI at all in the Medium Wave broadcast band.... I paid $14 each from a US supplier. I was happy to pay that...

[@Hacktuber]

Glad it's working great for you!👍

[@Zerpentsa6598]

Trump should slap 500% tariffs?😂

[@roeloftooms]

As this thing is advertised as a buck/boost converter you did not show the boost capabilities. On the 12v supplied voltage, can you still go up to 30 volt? And how is the current limit at that voltage.

[@y2ksw1]

I have 2 buck/boost devices, one to charge a 12V battery, one to feed my PC and screen at exactly 12V. Perfect solution for independent powering tools.

[@Hacktuber]

That seems like clever solution,good for you👍

[@neddy1287]

I like these buck convertors that have the ability to adjust and set voltage and amps

[@Hacktuber]

These days you can find some cheap and useful electronics

[@neddy1287]

@@Hacktuber Yeah these ones in the video I do be looking for. I have a similar one but it way bigger but I have to manage the screw pot for current limiting manually but everything else I can set the voltage and go

[@DonnyHooterHoot]

I use one of these to provide 1.4 VDC filament voltage on a tube radio. Cool!

[@Hacktuber]

Nice, that's a clever use of it!

[@JustMe-s6s4m]

These come in 2 versions. 4KX is 35 Watts, 5KX is 80 Watts. Cheapest I can find right now is about 7 dollars for the 35 Watt version and about 10 for the 80 Watt version.

[@dgedi78]

same, he just googled the article and it's a "welcome price"

[@paolopetrozzi2213]

watt or W, not Watt

[@twr4641]

also always be patient and wait for their „specials“ at regular intervals. For example, today are higher prices than tomorrow when they start their „black Friday“

[@Luke-san]

I also have this and a couple of other ones feg SK120 ... . I seriously like this one. Cheap, not a ton of useless options that you forget about after you tried them and it just works. Also an LCD which is visible outside, The only thing I can't understand is why that they don't make a cheap plastic housing for it. Not everyone has a 3D printer and the metal ones costs like 3 or 4 times the price of the module. At the input I use a XT60 connector which I can connect to my solar panels or the Powertools battery which btw I also charge with this module. Perfect quick portable powersupply with a large voltage and currect range. Only downside, but not a lot is the efficiency but that is just to have a negative point.

[@Hacktuber]

Very well explained sir,for the money the gadget worth every cent,its small portable and can handle 4amps which is enough for many experiments

[@mariebaxter473]

Regarding the housing , lots of people will add this to an existing transformer housing or project as a finishing part , so would not really want a housing that gets tossed into landfill.

[@SteffenBoserup]

The 3d printer was not invented, when I were learning about electronic - I used expensive boxes, which I got from electronic stores, and often I just sourced an retired plastic lunchbox, and modified it to suit the purpose - a hot glue gun and a dremmel are nice tools to have...

[@Zerpentsa6598]

They do sell one complete with black housing.

[@Luke-san]

@@Zerpentsa6598 yeah I know. Price is more than double that way.

[@christopherperry8693]

Good value, even at the higher price, adding a small fan to the heat sink helps at higher amps/volts. Rotary controller gets "sloppy" over time.

[@Hacktuber]

I need to test that rotary pot👍

[@andytraiger4079]

Need to monitor the DC voltage with a scope and have the power supply powering an audio amp or something high current and switching. Then you zoom in on the DC level and see if there is ripple.

[@DustinWatts]

It is a nice power supply for the money, but setting voltage and current takes a lot of turns :) Or did you find a course adjustment?

[@Hacktuber]

When program button on left side is pressed you can choose which decimal to set

[@DustinWatts]

@@Hacktuber Ow ok... that is nice!

[@DustinWatts]

@@Hacktuber Ow that is handy! Nice!

[@KA9DSL]

I'm using one on my coffee table. It works great!

[@Hacktuber]

I dont want people to think that I sell these with affiliate, ,search by name

[@Edmorbus]

@@Hacktuber thanks

[@toycoma98]

You put the red wire in the (-) output.

[@lohikarhu734]

Well, the version that I have seems to do the current setting quite accurately, but the current output reading seems impossible to get calibrated. Voltage is off a bit, but seems easier to calibrate. I actually hate the interface, I really prefer to set the values with potentiometers, with digital readout of the settings.

[@Hacktuber]

Good info,thx

[@PF-gi9vv]

Be careful when charging your batteries with these; for some reason, they don’t respond well. Even though I set the voltage, it somehow overshot the target by almost a volt. This can destroy lithium batteries or even cause an explosion or fire.

[@mariebaxter473]

As they dont have voltage cut off and sensing , not sure they are good enough for lipo chargers ?prob okay for lead acid ? Ive found the B6 imax has all setting and cutoffs i need for lipo charging and should add well onto this unit .

[@PF-gi9vv]

@@mariebaxter473 you might be right, i would keep a close eye on it still 👍

[@frenchcreekvalley]

I thought it said that it is a Buck/Boost converter. Why wouldn't it go higher than 12 volts? Also, we should NOT call this thing a "Power Supply".

[@Zerpentsa6598]

Because you NEED to supply power to it.

[@richardlynneweisgerber2552]

What's funny is the ferrules you put on the wires sticking into it are what I was about to say everyone needs. Where did you find yours?

Good point👍

[@jantepas7511]

Thanks for sharing your knowledge.

[@Hacktuber]

My pleasure!

[@gartnl]

The short answer: no! Whatever you try, the Amp meter sucks big time. Calibration does not help. Ripple is a disaster. HF rejection non-excistent. It is a toy that allows for quick access to a wide voltage range, but no more than that.

[@cosmefulanito5933]

1:17 Not a potenciometer.

[@Hacktuber]

My mistake,its rotary encoder😉

[@vendettasnares]

Why would I ever again need voltage regulator if I have this so cheaply.

[@riscy00]

Not listed, hard to find and lot of misdirection for that price. It now $6 minimum. It just other item goes to junk bin

[@Hacktuber]

Look on ebay or amazon

[@drinkintea1572]

i want to use these modules for a custom voltage injector tool (with a pc power supply) could it work tho?

Yes if you hook up with psu will work

urs is ZH-4KX = 4amp .... there is ZH-5KX = 5amp with a fan

Buy that with fan its better

You forgot to check if current measure is accurate.

[@Hacktuber]

Good point! I will test that in a future video.

[@Electro_JK]

What's the maximum output load?

4A but its good to add small cooling fan if you use high current all the time

Lab means workplace, so technically.....

[@martinesproduction]

Sorry, but this is another clickbait from you. Such mini power converter is minimum 8 USD on AliExpress. In addition, you cannot call such devices power supply, as they need a power supply and they only regulate voltage and current after being DC power supplied by another device.

[@Hacktuber]

Thanks for your feedback, I'll keep that in mind for future videos!

ok the $2 is one time price for new aliexpress account not existing, some cheaper module are PWM not DC/DC and starting price for existing aliexpress account start from around 5-6 USD with free shipping if you lucky. The ebay is $13. It used to be popular in aliexpress but now hard to find as they don't make them anymore. In general, the Aliexpress seems to be increasing the prices for cheap China craps. I have been grabbing many cheap things before Trump's policy imposed Tariffs and barriers which shut down or limits this trade route. The regulator device is a cheap copy or clone from the original manufacturer, which means inferior quality. I know I saw issues in various products from Chian crap, but hey, I still buy them because it's fun!. I expect during 2025, China is ready to move away from the USA and impose a policy to kick out US business in China once Trump implements harsh measures. They still have a market in another country. That is the way business works at the international level.
