Doesn’t seem to output up to 30v but..
With PD or 13v input it would only put out what the source was. Assumedly it doesn’t have a buck or voltage increase circuit.That said still 5 star usefulness. I don’t need beyond 14v typing. Very accurate with no load. .5 amp load, it may have dropped but also have been my load was RF based.It’s literally the size of 2 cell phones on top of each other. Very usefull and portable kit

AWESOME DC POWER SUPPLY W/PC SOFTWARE
This little DC power supply is awesome to use with your PC. I can use a USB-C 20 V 6.5 amp laptop charger to power it and it is great for fault. Finding on laptop motherboards. I use it for my YouTube videos. That way I can display everything on my screen. Definitely worth it. You can even use an additional DC power supply to power it over 20 V if needed. If you have a DC power supply already and want to be able to have that data on your PC for recording. This is also a great little additional tool.

Tiny power supply really works!
I was looking for an ultra small, usable power supply for my field work and found this. It really does help gat it claims, and pumped 4A at 19V with ease. For an hour. I was waiting for something to get hot or fry, but it didnât. Nice accurate controls and many configurable options. One thing to know is that you do need the optional wall plug to get the higher voltages. I didnât understand that at first. Otherwise, it will reference the highest voltage you supply it and will reduce from there. Itâs really small and well made. I own many of their products and this did not disappoint. The DPOX180H is so good, I bought too!

Nice and compact, but could be easier to use.
I have a couple of benchtop DC supplies, but I’m always looking for better options. This seemed like a handy little supply, and its ability to graph voltage/current output seemed like it could be a real boon.I’ve been a little busy lately, so I haven’t had a ton of time to spare for my electronics hobby, but I have played with this a bit, and I have some thoughts.Frankly, I don’t find it that intuitive to use; you have to remember the right key combinations to switch between graphing/setting modes. It does have a nice dedicated output on/off button (that lights up when the output is on), but accessing memory settings or changing configuration requires you to look up the right keys in the manual. I also find the selector wheel a bit hard to turn, making it a little finicky to adjust voltage/current. Also, there seem to be some glitches in the display firmware (see picture- the decimal point has disappeared), causing some ambiguity in the readout.Still, I do like the graphing abilities and the portability of it, and you can run it off a USB-PD connection, so I think it has a place in my portable toolkit. I haven’t tried the computer interface, since I tend to work on a Mac or linux, but that could be really handy for some (and probably take care of the user interface issues).So, overall it seems like a decent but somewhat flawed product that could use a bit more polish

Extremely accurate voltage for low power bench testing
> FNIRSI DPS-150 DC Power Supply Variable, 30V 5A Adjustable DC CNC Power Supply with 4-Digit IPS Display (~$70)The Good:+ The output voltage is spot on. My meter measured a 3/1000th volt drop, easily accounted for by resistance in my probe wires. Honestly, I can’t believe how accurate the voltage is (unloaded).+ Can be adjusted any time, with an output enable/disable switch.+ Uses PD over USB-C.+ Excellent screen is bright and informative.+ UI is quite usable, despite having to push buttons.+ Tiny. Smaller than most cellphones (but probably thicker).+ Can lock settings.The Bad:- I prefer turning independent knobs for each function, but the UI works well enough with buttons and a single shuttle knob. It may take longer if you need to adjust something.- Voltage is limited by what it can negotiate (minus a trivial 0.2v to power the unit). (It talks to my 45W USB-C supply properly and can deliver up to about 20v.)Overall, this is a really great item for a portable or small bench.

Only requests 5v on my PD 3.1 charger and 12v on my older PD charger.
This will let you down if your plan is to power it with PD3.1. I have to use the barrel DC jack to get it to use more than 12v. I’m not sure if they messed up the firmware, or if the hardware itself has a PD protocol problem. I can say for sure that my PD 3.1 charger will output 20v with other PD devices, so, it’s not the charger.

Cool idea, poor execution
I love the idea of this thing – but the firmware and UX are pretty bad. I really wish these companies would release a basic open source interface and API – with all the hardware work done, plenty of hobbyists would have a field day making custom firmware.

Very nice little PSU. Until you have one and try it out you won’t realise how useful it is. Very accurate readouts. If you ever lose a USB charger or indeed any charger up to 30V DC/5A this is a great emergency replacement…….if you have it! I power it from an old 19v laptop PSU (5.5mm/2.5 barrel plug required) and also if I need to, a PD-type fast charger PSU via USB C
