This thing is absolutely incredible but sadly way too expensive for those that this would apeal to most
Why? Miniware stuff isn't cheap but it costs about as much as it has to. If you're short on budget, get any of the numerous panel mount modules, with 4kx being able to do a lot or things on the cheap.
@@SianaGearz Those most of the time have INSANE ripple and arent too accurate. I know the thing is quite cheap for what it is but it aims to be cheaper
The parameters of the module itself are very good, I was unable to register consistent noise and ripple with the Rigol 1054Z oscilloscope (they are so small). It is a combination of a dc-dc buck-boost following converter and an LDO regulator at the output. Rarely found in cheap power supplies.
Unfortunately, the device itself is too small for comfortable work, this is the main disadvantage. If only it could be controlled from a PC, would be much more useful.
Excellent answer. Jakiś czas temu robiłeś na swym kanale świetny test tego zasilacza. Fajne cacuszko. Pozdr.
I love the form factor. Desk space is real estate. PC Control would be awesome indeed.
Hopefully MiniWare will come out with the remaining modules they have been talking about!
i contacted them half a year ago about that and got no response.
these units are so old by now, i doubt they are still working on new modules
@@ChriFux The new P906 higher power unit just came out recently! So who knows what the future holds :)
I use the wireless feature! I install low voltage security systems. I remotely trigger the power supply to deliver voltage to a device im testing, which could be several rooms away. This allows me to test that a lock is installed properly without having to fuss with authentication to properly trigger the door unlocking. There are so many other uses I've been finding love this thing!
just a suggestion. When making measurements with the oscilloscope, always try to maximise the waveform on the display, both on the voltage axis and the time axis (you need at least 3/4 full periods to get accurate time measurements).
Yeah, most oscills only show a measurement of what is visible on screen. If the waveform is compressed, so will be the measurement.
Just another quick note from an old 'scope guy; never, never, never, use that so-called "ground lead" when looking at power supply noise... most decent probes come with a little 'spring thing' in their accessories, which slips over the ground part of the probe barrel...so, remove the hook part, which exposes the probe tip and probe barrel 'ground', slip the spring adapter over the barrel, leaving the sharp part sitting about parallel to the probe tip, and use that to connect to the 'ground' of the power supply, and the bare probe tip to the 'hot' side of the power supply.
The probe and ground lead, together, form a resonant circuit at about 80-125 MHz, depending on probe capacitance and 'ground lead' length
I reviewed this too about 6 months ago, it performs very well, only mine blew up on camera and released the magic smoke, I repaired it in the review and carried on LOL
This was a great review. I was hoping that you would include its efficiency.
I have this setup with the display and both the P905 and P906.
Two obvious issues are that they're not isolated, so not good for a bipolar supply unless you have two isolated power sources, and the 4mm spacing which is non-standard.
The display frankly is of little use to me: perhaps when {if} they have other modules that will change.
A matching battery would be most welcome.
The P905 isn't USB PD 2.0 compatible unlike the newer P906 which is.
The UIs on the power supplies and the separate display are awful, but the build quality of all devices is excellent.
My use case is a handy lightweight PSU on the go.
The marine service industry will love it as well as any remote tech.
I use a bit older 5a version in my repairshop every day. Typical use case - inject 12v to imitate battery if i have some macbook with no spare battery and i need to isolate power issue to charging issue.
Short search, temporary replacement of absent power input and of course amp oscilloscope is a real help in troubleshooting power sequence issues on pc laptops.
Nice, it's finally out and now even support USB c PD
Take my money ❤ love this
Nice review video
It's a very cool product in my mind but premium and kinda niche.
If it was a very high quality power delivery like a filter without your own AC adapter especially at the voltages that really matter like 1.2/3.3/4.2/5/9/12/18/20/24 I imagine it could be a decent piece of mobile kit but I guess at this point you could just lug around a AC PSU Filter good enough for it
Gorgeous Device

Would you be interested in doing a how to video on making a Portable Power Station with out put of smooth 220/240 volt AC with maybe about 1500 to 2000watt output load plus easy add on battery capacity. Maybe a solar top up unit to go with it. I note all units of this capacity are quite expensive. Cheers Ash PS. love your work.
Very smooth
Holy crap this thing is nice. I’m in love with it. I was thinking in designing one similar with ESP32 and Arduino.
I'm pretty sure that the Miniware box is using a DC/DC converter, followed by a 'slave' linear regulator...the DC/DC would be set up to give, maybe 500 mV of 'headroom', above the dropout voltage of the linear stage, so that you get a lot of the size and flexibility of the SMPS, but with a 'cleaned up' output ...
I'm glad you said something, it would have been an awkward review otherwise.
miniware: no more free goodies for the kangaroo
This looks great, but that price is crazy considering it doesn't actually even come with a power adapter
For those with a teensy tiny workbench , or those with excess cash and a gadget addiction.
lol ill take the meanwell driver lol i have a couple of them but im using them with my grow lights lol
I guess most people have a USBC power bank of a power supply they can use on it
I have like 10 Milwaukee batterys
So part of the cost is something you have allredy for a huge percentage of people
Simplify it and it should be an affordable and popular item
First thought: I want it!
After looking at the price: Never mind...
I hate that 'fur' of switching noise these kinds of switching supplies always seem to have. Another spec that would have been 'interesting' to verify is how many peaked harmonics of hash are present in the RF realm which can quickly become a right pain in the pahtotee at the lab bench for near field....
What kind of power brick are you buying for $100? It doesn't appear to even be a USB-C supply based on the barrel jack, so I'm a little confused.
You supply it either with a USB C adapter or through the barrel jack.
The USB C is power limited to 100W as per the USB PD 2.0 spec. The barrel jack will go up is 4.2 to 30V, up to 14A.
that was just a random power supply to signify a good power supply. You will need a high quality power supply like the MeanWell shown
I have one of these and the USB C never worked properly - I dont think it was correctly implemented.
The DC barrel input works fine though
this could be useful for 5v rails on high end amigas, all pc powersupplies have weak 5v rails as they are designed around 12v hungry modern pc stuff and amgas are very demanding on the 5v rails.
I wish it would have the function to Log the values
Great power source for a bomb with the remote. LOL
Since USB PD is fully capable of adjusting voltage and provides oved 120W of power, I would be fully satisfied by a simple miniature controller for my 120W phone brick.
Those power supplies are not very...good in any way. High ripple bad controllability but if it fits it sits
If the power supply were plus minus, it would be truly useful
This psu is for Makho, next question
wow awsome product i bet it cost an arm and a leg tho lol i really do like this power supply lol man i hope im sill alive in 10 years i can only guess what its going to be like with teck in 10 years lol and much cheaper
Just looked on AMZ - make sure sitting down before checking, and thats with out the display
Agree 50 bucks would be okay, 300 bucks(the real price the ask) not okay.
Realistically, a "good power supply" for this is an old laptop power supply - I found a very tiny 90w unit which is about the same size as the miniware.
Of course, the price is unreasonably high. I hope the Chinese will make a cheap analogue.
Hmm, this is exactly what I need if I ever revive my atomic clock.
These days it's all about efficiency!
Great device ... but the price i way to high :/
Harga sepaketnya Rp 3.500.000
I'll stick with a boring, bench top power supply I think.
I'm always curious about those enclosers they used for those niche market products like this, I bet this encloser was designed for something else and they repurpose it for this power supply, maybe it was designed for a media player or so, but I don't think they design it for this power supply, the cost of tooling would be too high.
Edit/ Just look up the price, that price is way higher than I thought, so maybe I'm wrong on this one. I thought it was a 50 bucks product. The price on amazon EU is 289 euro send form China, so you must pay import cost.
In China, it is $80
I agree with your final assessment, but your methodology for measuring ripple leads to erroneous measurements.
1) Maximise the waveform on the display, as other viewers have commented.
2) Your probing technique is not great. This leads to higher measurements. If i may suggest "EEVblog #594 - How To Measure Power Supply Ripple & Noise". Its a great introduction to improve your future ripple measurements.
Schade das man sich so an diverse Firmen verkaufen kann..... Dein Kanal fing mal so gut an.
.??
Bruh
Tech for the sake of tech! Waste of money
if only it went up to 60v
The Ripple measurement isnt exactly...good. Should use an actual power analyzer or for cheap a differential measurement
I love boring bench top power supplies.
lol i was wondering how you powered these things lol man i wish i had your life even tho i loved everything i been threw and i loved prison and didnt want to leave lol but yeah ive been to jail over 10 times and yep im a good person slash kid but you can go to jail when your poor and homeless so yeah such is life lol but yeah i love stuff like this even tho im a felon
I appreciate your review, but I never understood people who, when a feature is something they would not use, immediately have a bad and sarcastic opinion about it.
Please always assume that there are people who needs those features. Many of them only dreamed about those...
People on the go, people living in a van, a boat, people who have to repair stuff in the field, etc etc... are all love these features, so please stop being like this...
gimmick...
lol ill wait another 5 years and then all this stuff will be affordable lol so yeah i bet this wont even cost more then 20 dollars in 5 years so yeah everyone save your money and wait till it gets cheaper in like 4 years from now and really it will be hallf the price by 2 years from now lol so just wait till it gets cheaper or someone comes out with better for the same price lol
Overpriced crap.
450 NZD? 😬
