A power supply that needs a power supply? More like a very fancy variable buck converter.
That's what I thought. If it was boost/buck it might be more worth while.
A regulable power supply that takes your fixed voltage power supply and regulates the output power to your particular needs
@@franukito No, it's not a power supply. It's a device that can regulate the output of a power supply. I'm not saying it's not a nice unit, it's just not a power supply. That's the thing that plugs into the mains and it's not included.
@@Ni5eisemantics.
It is a variable bench power supply that requires a fixed power supply. This is a step up from those bulky and heavy bench power supply that takes in AC directly from a beefy power cord. The footprint of this is extremely small and way lighter/portable. Any person who owned a conventional bench power supply will definitely understand this.
Looks nicely portable. Don’t EVER believe what the specs are on the box of a chinese company’s product though! Haha!
5A rated components for smaller electronics have become pretty cheap so there’s not much reason to believe, given the fairly premium construction, that they’ve taken the absolute shittiest route on the internal components. Most of the claims can also be tested by the average hobbyist/enthusiasts (or really anyone with a multimeter but, honestly, who else is buying DC power supplies?)
This was tested by EEVBlog recently. The item is on the premium side and the price is reasonable enough for you to not get crappy specs.
never trust Chinese on Chinese products
haha
He tests the outputs in the video
このビデオ面白かった。ありがとうございます。
A great explanation and tear down. Thank you, I really enjoyed it 🙂
I just received my DP-100 and it's a great little device.
20V from a USB-C is fine for my needs as I rarely need more than 15V.
Very impressive. TNX!
Hi thanks for the very excellent review It looks impressively built Expecially for the silly price Kind regards gino
Looks like some good engineering. The only thing missing is the ability to connect to an app or PC for some measurement monitoring and automatic graphs😊
scroll down in the description
i like the thin 65w voltme usbc charger. i always have with me for my laptop. both fit in my pocket theyre so small. only 15usd on sale sometimes
It looks nice. If it was a bit longer & had terminals on the front i would be in.
What socket is used for the external dc power supply, if i want to get output voltage of the device about 28V?
So basically it is a buck converter with a fancy voltmeter ammeter
This is a very neat device
Manual says 4mm negative is not tied to ground. Does this mean TWO of these could be used to create a dual rail (positive and negative) by tying the negative of one to the positive of the other? I.e. Like a dual output power supply. Thanks.
Which software/service did you use for the English translation?
Exactly what i wanted to know
Something I don't quite understand is the input voltage range: up to 32V. From what I know (but please correct me if I missed anything), you can only get up to 20V from USB-C PD. So how can you get over 20V? And thus, if the internal regulator is only a buck converter, you can't possibly get more than about 18V at the output (assuming that they have 2V drop out, from their figures).
Enlighten me, as I probably missed something.
because you can also provide the input power from bare wire,
you probably missed watching the video
The device is nothing more than a simple DC-DC buck converter, therefore it can't output a higher voltage than the input provides.
The USB-C is only 20V - so if you want more you have to use a hiigher voltage supply. Nice though, thinking about one even though I have a dual channel large 240V one.
⚠..yeah but not PD3.1, only PD3.0 because the max. output is only 100W & PD3.1 negotiates all the way up to 240W (48V @ 5A). Oh well.. maybe next version. 🙂 Still it's a nice little power supply. Was very surprised to see how tiny it is. 😮😎
Any software control????

I got a same one, bought it like $30, it is good, but I rarely use it.
That ossiloscope is huge just like Drake's

little spendy for what it is. more or less a PD trigger attached to an adjustable power supply.
Portable, yes. But you can buy a good proper 30V 5A power supply for the same or less money.
That's not the point of this device lol
@@Mom19 What? The titles is "DC Power Supply" and otherthan the portability, it sucks. Can't you even read. lol.
@@tianalucas4969 because this is a variable "power supply". If you buy a regular 30V 5A PSU it won't be controllable, can't adjust current limiting or other factors. Yes I can read. But those 2 things have entirely different purposes.
@@Mom19 I'm also talking about "variable power supply". You can easily find even a 30,10 Sugon,RF4 or something under $50 in here.
@@tianalucas4969 which are not only more expensive but also bigger without support for PD input (very useful for power banks on the go) so yeah... While yes they are "better" from a technical standpoint, those aren't comparable in terms of function and goal of each product. This here is a fancy buck converter and is useful but a bit pricey. But I've also seen it going for quite a bit cheaper too. You can't really compare a delivery truck with a smart fortwo. Different use cases, different specifications, different products.
Excellent video. G7VFY
