FNIRSI Soldering Iron Kit, DC/PD(96W/65W) Mini Digital Soldering Iron, 180-780℉ Fast Heating, 6 Soldering Tips, Digital OLED Screen Display, Auto Sleep (With Power Adapter)

I have not soldered in years because I kept buying those cheap irons. I recently bought an old keyboard with cracked solder joints. After a week of research I decided to purchase this kit. The item arrived and was obviously used from the discolored tip that came packaged with the iron. However the other items were new in the package. After READING THE INSTRUCTION MANUAL, I correctly assembled the iron.The 100w adapter and usb cable did not get hot even after 2 hours of repeated use. The iron itself is the size of a permanent marker(in my hands at least). I do not recommend using the sponge that comes with the little stand. Purchase a Hakko 599B and a tub of flux.Overall good quality, this entire review was typed on the repaired keyboard mentioned.

Buena calidad, como nos tiene acostumbrado la marca FNIRSI.

excellent, it get’s hot really fast and it has a really good apearence

Awesome little pen iron! I've used it multiple times with a USB battery pack to solder 12 gauge stranded cables with no issues. It feels solid, and very well made. The tip and heating elements are solid with no wiggle or play in them. I've owned many irons including my expensive Wellers, and this little iron is by far my favorite.

Works good is nice, thought it was battery operated though…

I usually keep my JB pyropen handy for field soldering, but someone had one of these at field day this year, fixing the dc jack on his SDR. That was my first time seeing a usb-powered soldering iron, and I was surprised it had the power needed. But it's not USB-A, it's USB-C, and has a useful power delivery.He just had it plugged into a USB power bank, and it worked well. Electronic temp adjustment, and fast heat-up. So I got one for myself. Comes with a variety of tips that are buil onto the heating end, so when you change tips you're also changing heater. This places the heater in better contact with the tip, and they warm up almost instantly. Like you turn it on, and within 2 seconds the rosin that was left on the tip is already smoking.There are a few different kits available, but this one comes with several tips/heaters. a chunky AC power adapter (that works great to charge phones too) as well as a hyper-flexible USB-C power cable. It can also be powered directly off 12 volts via the included barrel adapter, though I don't know how that affects the power output. Honestly, just the inclusion of that nice 65w USB A/C power adapter alone makes this kit a great value. Comes with a cover for the tip too so you can close it up and put it away immediately after use instead of having to wait for it to cool.The super-flexible cord is a nice plus, it gives me better fine control of the tip than any of my other irons that have stiffer cords on them. I also like the rubber grip on the end, it's very comfortable. I was a little concerned about what looked like proprietary heater/tip units so I looked around, and was satisfied to find several vendors selling replacement tips. I ended up buying a set of replacement tips to have as spares just in case.My set didn't come with a travel case though so I ended up packing it all in a small iPad mini box for now. That's the one thing I'd change - include a fitted travel case for it, since it's being sold as a field soldering iron.

I have two kits - my (now discontinued :( ) FX-951 with all the trimmings back when that was $400, and this. This thing with a good insulated 65w power supply and an RC battery are just about better than the Hakko. It's got some useful (if bizarrely accessed) settings, and responds well to the current it has available. Give it a 24V battery and you can do car lugs with this thing. I retrofitted some wood burning irons and it runs those too. I haven't managed to burn it out yet. What my Hakko has in precision, accessories, and workroom workability, this has in adaptability and tenacity.

First of all the unit that I have will only adjust to 20 volts, that might be different with a firmware update, but I don't have time for that. So at the max setting of 20 volts, it will draw more than 25 watts when it heats up (10sec). After it heats up no matter what tip or what you are trying to to solder, it will not draw over 25 watts continuously. This is a 25w soldering iron at the end of the day.
