Reviews FNIRSI DPS-150
Authentic Feedback Analysis:
⭐ 5.0/5 | B***r: A good and convenient power supply. Thank you.
⭐ 5.0/5 | 今***也: I was able to purchase it cheaper than on Amazon. The packaging was solid and there were no dents. This is definitely better than a large regulated power supply! The operation is simple and can be done intuitively even without a manual. It’s a shame that the manual is not available in Japanese. I am satisfied with the product.
⭐ 5.0/5 | AliExpress Shopper: Beautiful, delivered fast, everything okay, FNIRSI is a guarantee.
⭐ 5.0/5 | r***n: Good equipment, no issues for now.
⭐ 4.0/5 | V***n: Good product, +-0.3 V is the voltage variation, very functional.
⭐ 2.0/5 | A***h: Could have been a nice little power supply, if the designers did not have the bad idea to put a DC connector to which practically NO POWER ADAPTER CONNECTS ! This is due to the THICK pin inside and makes the device pretty useless. At that price they could have added at least an adapter!
⭐ 5.0/5 | C***o: It fulfills what was promised, arrived within the estimated time and was well packaged.
⭐ 5.0/5 | R***l: Everything delivered perfectly, like all FNIRSI products, good material and quality. I have several of them and they are perfect. Seller and store recommended for anyone who wants a good product.
⭐ 5.0/5 | S***n: It’s great! At first it’s a bit complicated to configure but once you get the hang of the buttons it’s very simple and fast.
⭐ 5.0/5 | C***a: Everything arrived perfect… The best purchase I have ever made.
⭐ 5.0/5 | C***e: Everything was very well packaged and in perfect condition. The package arrived sooner than expected.
⭐ 5.0/5 | C***o: Excellent versatile and reliable power supply. I tested the FNIRSI DPS-150 with an LED, a lithium battery (for charging) and a 5V DC motor, and it worked perfectly in all cases. I was surprised by its precision and ease of use. It is a very versatile and reliable power supply for electronic projects. I definitely recommend it.
⭐ 5.0/5 | s***r: Excellent, it works perfectly for me and the good thing is that you can even carry it with a portable battery. Because it is so small.
⭐ 5.0/5 | AliExpress Shopper: excellent product (for its product range). Convenient price and fast delivery.
⭐ 5.0/5 | AliExpress Shopper: Excellent, works exactly like advertised.
⭐ 5.0/5 | AliExpress Shopper: Feels really nice and it seems to be quite accurate. I was able to drive a 25W DC Motor with it no problem.
⭐ 5.0/5 | K***s: Great power supply. Voltage and current measurement is accurate to the last digit. Constant current mode works fine. The form factor and ease of use is excellent. The user interface is top notch and very intuitive.
⭐ 5.0/5 | 9***r: Great stuff. I got output 117V with QC adaptor. LCD quality is just OK. We use to OLED phone’s screens 😂
⭐ 5.0/5 | R***h: High Quality Power supply. This gadget is so cool. I can connect it to my PC and use a desktop interface to control the current and voltage output and also the signal generator. Fast shipping to canada.
⭐ 5.0/5 | P***m: it seems, very good power supply.
⭐ 5.0/5 | AliExpress Shopper: Item is received in good order. Looks well-delivered and ok but have yet to test it. Will put it through some functional tests later and update. Thanks.
⭐ 4.0/5 | A***r: Item will not work with PD usb connection. Tried multiple cables and PD power supplies. Otherwise works as designed and I look forward to using it on future endeavors.
⭐ 4.0/5 | AliExpress Shopper: It’s good.
⭐ 5.0/5 | u***r: The power supply is smaller than expected, very portable and with good finishes. It seems to work well although I haven’t done many tests yet other than seeing if it turned on and a bit of the menus.
⭐ 5.0/5 | M***n: The power supply arrived in perfect condition, ideal for electronics work 10/10.
⭐ 4.0/5 | AliExpress Shopper: nice small and handy device.
⭐ 5.0/5 | L***z: arrived well, still untested.
⭐ 4.0/5 | AliExpress Shopper: Arrived in perfect condition, everything works correctly.
⭐ 5.0/5 | AliExpress Shopper: Manual only in English or Chinese.
⭐ 5.0/5 | k***e: very good product arrived in excellent condition and ahead of schedule very well packed.
⭐ 5.0/5 | AliExpress Shopper: Very good product, it fulfills everything promised, it is very easy to use, compact and portable.
⭐ 5.0/5 | A***z: Very good product, just as described.
⭐ 5.0/5 | M***i: Overall, I ordered a soldering iron and a laboratory power supply. However, only the soldering iron arrived, but despite everything, the comment is positive because contact with the seller was immediate, everything was explained and I received a refund. I recommend.
⭐ 5.0/5 | M***r: ok.
⭐ 5.0/5 | P***k: Ok.
⭐ 5.0/5 | N***u: ok.
⭐ 5.0/5 | E***s: Ok, but a bit overpriced.
⭐ 4.0/5 | AliExpress Shopper: One thing which I didn’t like in this Voltage Regulator is the On/Off button. It’s surface is the same as surrounding surface, even no any gap around the button , and when you try to operate it on blind, you didn’t know where is it. As pros, the regulator keep stable very current.
⭐ 5.0/5 | N***o: Excellent.
⭐ 5.0/5 | AliExpress Shopper: excellent product, good quality, functional and very useful.
⭐ 5.0/5 | R***h: Perfect for small hobby projects. Tested with a USB PD power supply (max. 20V output voltage).
⭐ 5.0/5 | D***r: Perfect, runs 100%. Very qualitative, high quality and super function.
⭐ 4.0/5 | F***n: Pretty good power supply. Stable and very decent precision, and solid state. Overall nice build quality. The UI controls take some time to get used to, and I expect to still have surprises in store after a few days usage. Buttons and connectors on four sides is a minus. Use of non-safety banana-plug connectors a very big minus. It feels like they first thought about how many inputs/buttons they could fit, and after attempted to use them all in the software. Sanded down data on the various chips on the PCB makes it un-repairable. Wanted to replace the banana-connectors, but found no space to fit the safety types (green in the picture), so a chunky adaptor is needed. It’s still a useful item, but with a few changes it would have been a sensational item.
⭐ 4.0/5 | W***r: PRO: Good Quality, works great, portable design and small in size CON: No firmware files to download, power connector and cable does not fit into the case — this would be great if it would be possible (see pictures).
⭐ 5.0/5 | AliExpress Shopper: very good product, I recommend its purchase.
⭐ 3.0/5 | AliExpress Shopper: Quality of materials is very good, but over voltage is with too long delay, sometime over 4 amps is device restarted. adapter is only to 20V, therefore you neef buy other adapter for 32V if you need use full potential. New firmware with fixing the problem is missing. I see the biggest disadvantage of this product in the fact that the manufacturer supplies an unsuitable adapter. The device can work with 32 volts, but the adapter only works up to 20 volts. It’s completely useless to buy this if you want to use the full potential of this product. You’d better buy a product without an adapter, which you can later purchase elsewhere with the required parameters and 32 volts. I dont recommended this adapter, it is poor qality. Photo is from screen which appaear after restart and change maximum power to 65W.
⭐ 5.0/5 | A***r: Quick delivery and great price. Nicely packed.
⭐ 4.0/5 | J***c: It looks robust and of good quality, a very good product, I recommend it.
⭐ 5.0/5 | AliExpress Shopper: Super part, really great.
⭐ 5.0/5 | h***m: SUPER!!!
⭐ 5.0/5 | AliExpress Shopper: Husband very satisfied.
⭐ 5.0/5 | p***r: thank you Item as described very good equipment.
⭐ 5.0/5 | M***r: The parcel is perfectly packed. With power banks you can use. I am recommend.
⭐ 5.0/5 | G***r: The portable DC power supply looks to be well made. Powered on fine with the provided USB C cable and power brick. I haven’t tested it yet and will provide more details once I have.
⭐ 4.0/5 | V***i: The USB adapter is just not working as expected, it drops the voltage and the DPS-150 keeps rebooting randomly. The shop was willing to handle the case correctly, I got a refund for that item.
⭐ 5.0/5 | M***z: all good thanks to the seller.
⭐ 5.0/5 | AliExpress Shopper: Everything excellent, its PC software did not work, it kept freezing, I thought the software was poorly made but it turned out that the cable that came in the box was damaged, I put another cable and it worked perfectly.
⭐ 4.0/5 | J***z: All ok.
⭐ 5.0/5 | g***r: very nice power supply, practical for charging batteries or others.
⭐ 5.0/5 | 9***r: Goods arrived well packed. I cannot yet evaluate the usability of the product.
⭐ 5.0/5 | AliExpress Shopper: works great.
⭐ 5.0/5 | AliExpress Shopper: overall very well made, but the hole for the DC connector is shifted, which may prevent its use. From the back of the liftable display, its ribbon cable is visible, although it is not clear why it was made visible. The display seems to want to be touch-sensitive, but everything is implemented with buttons. The wires are thick, yet soft, and the alligator clips are strong — there will be good contact.
⭐ 5.0/5 | AliExpress Shopper: Cool voltage and current regulator!!
⭐ 5.0/5 | AliExpress Shopper: We must give credit to Fnirsi, they make excellent packaging, some of the best, both for the product itself and for transport. The DC converter itself is also good, I consider it a very successful and well-thought-out device, I recommend the DPS-150 and the seller.
⭐ 5.0/5 | AliExpress Shopper: The package arrived very quickly, everything works.
⭐ 5.0/5 | O***o: Simply a top product!
⭐ 5.0/5 | AliExpress Shopper: It’s compact and portable, can be used with a mobile battery, and is very convenient for various uses such as microcontroller experiments, testing 12V car equipment, DIY, and home appliance repairs. The only drawback is that it’s quite expensive on Amazon, but I was able to buy it for about 40% off on AliExpress, so it’s perfect.
⭐ 5.0/5 | m***a: Compact and good, doesn’t take up much space. Now for durability.
⭐ 5.0/5 | T***i: The manual is in English, but I could mostly use it without looking. I measured with a tester, and both voltage and current output accuracy seem high.
