Longwei LW-K3010D Switching DC Power Supply (Review)

This is the Longwei LW-K3010D Power Supply.

Hey, 3 year future me here: This thing still is truckin. I had to jerry rig the connectors cause they got corroded since they're cheap. For the price (still $65) you can't beat it imo... that is, if you don't mind dealing with the el'cheapo connecters.
Also this is by far my most disliked video I've made haha. I was still in high school and a free $65 tool was a big deal haha. Also, my jokes at the beginning 👌 💩

**Make sure you select the version with the correct plug for your country**

When i bought it, it came with alligator clips!

You should check the constant current as well in your review, since it is a power supply.

I got one from banggood here in Australia whilst is preforms its functions ok it has one thing that makes it non compliant to electrical standards, the metal case is not earthed so I would recommend that people open it up and fit an earth to the metal case here in Australia we use 240V as our general supply making it important.

Mine has just arrived complete with crocodile clips 🙂 Looks like they listened to you 🙂

Great video certainly proves how robust it is but just wondering did you calibrate the multimeter with a known precise voltage before you used it to measure the output of the PSU? If you didn't then the measurements will be worthless as you have no idea how accurate they were

[MattysWorkshop]

Thanks mate you have just answered my questions, I think I will be purchasing one myself, Cheers Matty 🇦🇺

Does the voltage spike when you switch it on or off?

[diyland]

Can you tell me what multimeter did you use? I sort of forgot it's brand. But I know that it's UL listed.

I'm looking for something to etch logos into steel, would this be good for that? Could you adjust it to whatever you wanted, like 12 volts, 2 amps.

[waelfathe]

got one today i notice that the current knob move freely and smothly however the voltage knob moves with little bit of friction? is that normal? thanks

My longwei came with alligator clips luckily.

[jamesrixon]

Video wasn’t that bad but fuck these comments were worth the read lol

[Berre]

Please fix that table, it is dancing all over the place.

[shnuk]

Did you ask them to send it to you for a review or they asked you to do a review?

[Lkabouter]

Sorry, this is no real review. Only testing of the display ?

[davidmcdougall]

I bought one of these. It lasted for about an hours use and worked up to specs but when I turned it on again all I could get was the display and no output and no control from the knobs. I suspect that there is a low voltage internal supply that feeds the circuit board and the electronics which seems to be OK but the switching section which provides the output has a vital component failure somewhere. Just about impossible to find without a circuit diagram. My suggestion - don't buy one! A waste of money~!!!! damanos

Why do you have so many dislikes? - I thought it was a pretty good video.. though i didn't buy this unit..

[thijs-p]

my current button does nothing please help

[GrizOnTheTrail]

I thought I was going to get a review and not a comedy routine. You would do much better with solid content, not reading the specs, and skip the BS. Didn't make it past the first minute.

Wow, this has to be in the running for the worst review on YouTube. I won't go into what's wrong with it, suffice to say I don't think there's anything right about it. And who the hell is a nortrical engineer. I wouldn't worry about telling them to go elsewhere to get info, I'm sure they cleared off right after you started. I can't say I'm surprised at the 800 subs, any surprise would be that you have any. You definitely give no reason for anyone to come back for more. Do you by chance watch other people's videos? They could teach you a lot, but somehow I doubt you're interested.
