DP100 PD-Power Supply 100Watt [0-30.00V / 0-5.000A) [∼50$]
DaneLaw:
Has anybody tried this small power supply that resamples the Miniware MDP series quite a lot. .?
It's tiny, at around 10cm in length 1½cm high, and 6cm deep, but looks quite feature-rich, with 4mm banana jacks fitted with corresponding red/blue ring lights when power is active, TypeC with fastcharge protocols like PD3, USB-A for peripherals like mouse-control, also seems to have a PC interface.
It could be a good fit with these modern high-wattage PD3.0 and PD3.1 power banks as a small mobile solution.
In transit and should arrive in the next week - A small switching alternative to the two bulky old linear Korad PSUs I got, which are cumbersome to pull out, and set up with PC control.

PC software that seems to have english support.. :-+
A look inside (+4.10min)

Hi,
Any chance you tried it?
I'm looking to order one too.
There is a review video (Japanese / subtitle available). It seems very good for the price.

They first arrived today, and its orders from Singles Day nov-purchase in one of Aliexpress's so-called "fast combined-shipment" where they will try to bundle it with numerous of your other orders from those weeks, but December month is a heavy shipping month, and the delay is likely down to our local PostNord that will gladly let your China parcel linger locally for weeks' before they will deliver it.
So I haven't actually tried it to any real extent, only a brief visual look today on one of them... its very Tiny..
The possible add-on "100W TypeC" cable comes in a separate box and the embedded chip in the cable reads it as "20V / 5A - USB3.2 gen2"
Overall it's a nice 100W 150cm TypeC-to-TypeC silicone cable with good lock-indents.
The black & red casing also looks pretty good with a riffled ingrowed surface-texture, though it has quite a fabrication smell to it, so it's on the balcony sprayed with some Rodalon so hopefully the smell will be a saga.
The incl. 4mm banana to crocodile clips are goldplated in both ends with silicone wires.(16awg 200 degrees rated)
Here at first glance, the DP100 unit looks good - and seems to match the description, the knurled metal roller, sadly aint clickable so you validate/enter with the front buttons.
The incl. manual does cover English, foldable with one side CN and the other ENG.(10 pages)

// with the price in mind, it looks like a nice unit (sofar) but also precuriously cheap, so still waiting to see where the cat is buried
(vers. 1.4_1.4)

Nice shoots! Thanks

I think the price is reasonable. I know it is generally cheap, but the RD60xx serise has more features and prooved performance with arround 64-112$ based on PSU and case selection.
DaneLaw:
The RuiDeng units, It's another fish, nobody would pursue Atomics DP100 or Miniware MDP-series, for PSU purposes, if size benefits weren't critical, then you would go with a full fledge bench PSU, if mobility & size weren't a crucial factor.
Sure' you can get a Ruideng control PSU panel for relatively small funds, but its two very different-sized products in build and design, the DP100 its tiny, to the point that many would see that tinyness as a con, if the tiny size wasn't something they needed.
Here in my taxed northern region, RuiDengs RDxxxx products are from. 130USD for what looks to be a barebone RD6012 frontboard (no wifi) and up, incl. enclosure-backcase it's 170 to 180USD and then you can add a PSU.. https://aliexpress.com/item/1005003472332331.html?
Already have two linear Korads-P units http://tinyurl.com/28upwfre and they are bulky as, (just like linear PSUs tend to be for the linear benefits) and certainly not mobile, and it's the small form factor in fx DP100 that is so easy to just pull out on your desk or outside, and attach with a high wattage power bank, that appeals to me, not least to running high powered 9mm laser diodes, as im fascinated by light, and particularly coherent wavelengths, where many of the high power lazing diodes nowadays are quite resistant to switching PSUs.
DP100 48 USD (incl. 25% EU-VAT and delivery) but it is a sale price (BF/SD sale) where Aliexpress eats a good chunk of the price & takes it down a nudge http://tinyurl.com/mupskyju
Been very close to take the plunge on the Miniware variant since it came out "MDP-X" fx 905 but the more I looked into it, the more limited it seemed hence the choices Miniware had gone with, though Miniware did try to counter some of the shortcomings with later revisions, not least protocols.
The fanless MDP P905 (90W) which in the standalone version costs around (160USD) though P905 discontinued now, for a beefier variant P906 (220USD / Eleshop) which is now also holding a tiny hysteric fan (not dat creazy about that) likely a must in such a small form factor, being able to reach 10A.
I'm not familiar with other alternatives, then the Miniware MDP PXXX variant and then the DP100 from Punctual Atomic, all other units seem to be in another adj. PSU category, also RuiDeng units.
So far I do like the protocol approach in the DP100, as you have quite big control over the power delivery/PD and Qualcomm protocols when supplying power.
PD (to a type C PD socket) you can cycle at will in the DP100 menu, 9v, 12v, 15v, 20v, and your power bank or PSU will adjust accordingly on the fly.
Qualcomm quick charge (when using power from a standard USB-A port) you can cycle between 9v and 12v.
Tried with an Anker737 power bank (PowerCore24). it got 2x TypeC (PD3.1) and 1 USB-A (QC support).. the 2 TypeC sockets would cycle 9v, 15v, 20v (this 737model PB doesn't support 12v PD) and running it from the USB-A port would let me choose between 9v and 12v (QC)
You can always just supply ordinary non-protocol power, to get above 20v, as the unit doesn't support PD3.1 which opens up for fx 28v/5A (140W) DP100 got PD3.0 as far as I can tell, that maxes out at 5A 20v (100w)
The Anker737 power bank supports PD3.1 and 140watt of each of the 2x TypeC sockets, so I attached a PD3.1 28V 5A decoy/trigger cable, so the power bank triggers 28v-power delivery out (PD), and that works fine, gives you 28v input on the DP100, - the DP100 is solely buck'ed, so your max will be around 1v lower than your input.
If you dont wanna rely on protocols, you can obviously also do that, fx from a barrel DC, as it comes with a DC-barrel to TypeC adapter that does seem quite beefy hence the metal in the small cable part, likely rated for the 100W.

Tested to see if it overshooted and to what extent...tested when turning the device on & off, and tested when turning the output on & off..
could look like there is some when turning the output off (peaks with +0.4v from 15v output, a brief spike to 15.4v before dropping), and when turning the DP100 on manually with the left button, the same spikes with around +0.4v to 0.400mv before centering. (not the actual output, solely the device on) but there are quite many variables, as you can also set it to turn on aut when connecting the power bank (was using the 737 Powercore24)...
Will try to hook one of these on the input from the power bank to see what it gets in.
