FNIRSI DPS-150 DC Power Supply Variable, 0-30V 0-5A Adjustable DC CNC Power Supply with 4-Digit IPS Display, <20mV Power Ripple, PD/QC/DC Input, PC Programmable Regulated Switching Power Supply

Transitioning from electro-hobbyist to doing repairs for organizations and individuals, I desired to level up to a polished, easy to use PSU with all available limits / protections, in the most compact design available for my mobile repair kit. This PSU is larger than the dinky versions I'd previously used, but with wonderfully polished feel, design and interface. GREAT screen display, easy to learn, and great banana jack ports, with collar to unscrew and apply C connectors. Chose to get the bundle with 100W PD block and the 'feel porn' perfect soft bendy high wattage C cable. I have those same cables from the Fnirsi HS-02A irons. The PSU functions seem to work great. Intention is to make small adapters for most power interfaces I come across, and simply apply to other end of banana jack cables already on hand. Eager to use this PSU for prototyping in the field as well. From my very positive experience with their customer service, I trust their warrantee support Fnirsi DOES charge a bit of a premium for their polished products, but in my experience they have earned that. This same bundle (with 100W adapter and cord) was available on AliExpress at only $5 less during the Amazon Black Friday period I got it, so I feel this is definitely a worthwhile gadget for a serious hobbyists kit when discounted on Amazon.

This is a convenient little power supply if you have a crowded workbench. The power leads are good quality and a bit bigger than needed, I ended up swapping them with the ones on my main bench power supply. Voltage output is accurate and the display is clear and easy to read. Once you have it set up, the enable button is easy to use and it's easy to switch from one stored setting to another. The initial setup was a bit confusing, but I eventually got things set. The display stays on when it is plugged into USB C; you can use the tiny PD-PS switch as a main on/off. The 100W power brick failed after 3 weeks; Fnirsi reached out and offered a refund, so in case you do have problems, customer service is good.

This is a fantastic little power supply for the price. The small form factor is incredibly convenient, and the IPS display is a huge plus—it's bright, clear, and easy to read. I've found the voltage and current adjustments to be very precise, and the programmable features are a nice touch for more complex projects. The multiple input options (PD/QC/DC) make it super versatile for use in different settings. My only real complaints are minor. The fan can be a bit noisy under heavy load, but it's not a dealbreaker. Also, while the manual is decent, some of the more advanced features could use a bit more detailed explanation. Overall, it's a powerful and accurate tool that's perfect for hobbyists and professionals alike, as long as you can live with a couple of small trade-offs. It's an easy 4-star product for me.

Extremely handy and makes my life easier with figuring out power requirements before I waste money damaging sensitive electronics bits on DIY builds. Great build quality as it feels sturdy in hand, not to heavy not to lightweight. The cable connections feel secure. It tells me what the wattage is going into the device and I can very easily dial in amperage and voltage. The price for the money is actually very good. This is my first time using something like this but I wish I had it a lot earlier when I first started building. This allowed me to figure out the power requirements for some led filaments without melting them down. The size is extremely portable so I can work out in the field with it. The voltage is limited to smaller builds below 32v and you can’t work with AC with it which is kind of a bummer, but I am new to using these devices and I will definitely need a bigger one but this is a great starting point

This is an amazing tool! easy to use, lightweight, great functionality, voltage range is what you need for pretty much all your hobbies needs, quiet, charges fast and great value for the money. Recommended!

So far this power supply has been great. Controls are easy to use once you live with it for a while and the presets for different outputs is super handy. BUT, and this is a big BUT, this is not a step-up power supply, only a step down. This means that it will only output as much as you put into it. So if you power it off of USB, you'll only ever get 5V output. In the majority of cases this is fine, but I was really hoping to be able to use this as a lightweight mobile test rig for low draw 12V testing of relays, solenoids and other small devices using my existing USB power banks. This just means I need ANOTHER power bank that supports 12V+ output, which is easy enough to find, but not from reputable brands like Anker or Ugreen so hopefully I can find one that lasts.

A mini benchtop power supply that I'm using for working with projects and development boards at my desk for when it's not practical to have things at my workbench with my full sized bench power supply. It works better than I'd hoped. The unit is well built with an aluminum case. The screen is bright enough to easily use outdoors where I tested using it with a USB-C power pack. I've tested the voltage outputs and they are very accurate. Here are the outputs that I set and tested with no load: 0.25V = 0.248V 1.00V = 1.000V 1.20V = 1.199V 2.50V = 2.506V 5.00V = 5.017V 9.00V = 9.025V 12.00V = 11.99V 15.00V = 15.00V 19.00V = 19.00V Under somewhat heavy loads there is drop, but that's to be expected. It does a great job for what it is and is perfect for portable devel boards. The screen can flip up, but that's one thing I would prefer it didn't have and instead have a flatter profile, but I'm sure that's a useful feature for some. For those not clear, this unit is USB-C powered, so you can use a high current USB-C wall adapter or a portable power pack, though you're not likely to get as much current out of the power pack.

I bought this for my daughter that's in school. Out of the box the unit was fine and worked better than anticipated. Very nice form factor and easily packable. It powered all of her electronics that she needed it to. That being said, after about 2 months, the unit started having sporadic issues and the power output was drastically reduced. Still worked ... kindof ... but after the return window was over and couldn't return it for another one. As much as I liked it the first two months, I can't say this is worth it as it's still $50ish and should of lasted longer than 2 months.
