Review: Polished, compact and user friendly serious hobbyist must have - 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 desertcart Black Friday period I got it, so I feel this is definitely a worthwhile gadget for a serious hobbyists kit when discounted on desertcart.
Review: Nice power supply, really convenient, good customer service - 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.

### ⭐⭐⭐⭐⭐ Great little power supply!
*by L***M on January 19, 2026*

Don’t let its compact design fool you - this little device is great! I use it to test different handheld game consoles, full size consoles and retro toys - none of which typically need more than 12V, so it’s perfect for that application. The screen looks amazing and the information it provides is useful. I really like FNIRSI tools and this is one of my favorites and most used. I love how small it is - it doesn’t get in the way on the bench like larger units do and it performs way above expectation. It is also very simple to use. Personally, I think this is all the power supply any electronics hobbyist really needs.
