FNIRSIHS-02B 100W Portable Corded Soldering Iron Kit, 2S Fast Heating, 212-842℉, Pre-set 3 Groups Temperature, 3 210 Soldering Tips, Smart Digital Soldering Iron Pen for Electronics Precision Repair

If you're in the market for a small soldering iron, Look no further. Get this. having owned multiple soldering irons, both electric and butane powered, from established home improvement brands and hobbyist stores, I was extremely surprised that this small soldering pen easily best them all In every way. Size and form factor, rate of heat Maximum temperature, precision, ease of use and presets, and included accessories. The device looks and feels well made and solid, powered by a 100W USB-C power supply that also fast charges my phone and can do so while powering the iron thanks to the (2) USB-C and (1) USB-A 3.1 power output ports. The carrying case is small yet holds the soldering iron, with room for all three included iron tips, straight point, angled and flat blade, one in the iron and the other two in their protective hard sleeves, the iron tip itself is protected with a cap that twists on, nearly eliminating the possibility of the cap falling off on its own with a hot tip exposed to damage or potential burns. The USB-C cable included is solidly made with a silicone jacket and is extremely flexible with quality feeling metal connectors. A small iron stand and thin piece of sponge are also included in the case. The tips push straight into the unit and are securely held in place no need to twist or tighten anything. Upon sensing the presence of a tip the iron temp can be set manually, or to any one of three preset temperatures, which you can select in the settings, to have easy access to your most frequently used temperatures for the type of work you do. The screen is bright and easy to read, and silicone grip near the tip of the iron makes it comfortable to hold to solder precise joints. With other soldering irons I sometimes ran into issues of the tip not heating up enough but that has never been the case here. I always have enough heat to melt any gauge solder exactly where I want it for perfect connections in my electronics and metal connections. For everything except the largest of soldering jobs, this is the only one you'll need. Highly recommended.

So far it heats up quickly and seems to do what is described. It alludes to be wireless but it is NOT WIRELESS…which is why I bought it. But it can be used for really tiny soldering jobs. I wish the were more tips sold separately, but I don’t see any.

This soldering iron has been the single greatest soldering iron I have owned. I am able to quickly tin the wires and projects I have with ease. No joke, it heats in seconds. That is amazing and works well with the small soldering projects. I can keep this in my go-bag for on the go projects or helping others with small soldering projects. Love it. This model has made me love soldering all over again.

This is the best portable electric soldering iron I've found! An absolute must for field work and on vehicles and such. It does require using a portable USB-C power pack, but that's not a big deal and the included flexible silicone USB-C cables are great. I've tested this with soldering fairly heavy gauge wire using lead-free solder and had no problem with it. The tips aren't my favorite, but they are versatile so I'll just get used to them.

The media could not be loaded. Unit is very nicely made for sure, but despite the "quality control" badge in the box, the one I received did not work (it wouldn't heat up correctly). Seems like if anyone was actually testing these soldering irons, it would have been easy to catch this in a few seconds.Okay first off: make sure you understand this iron is *corded*, not cordless. That means you must always have a USB cable plugged into it for power. There is no internal battery to charge up. You wanna use it, you plug it into the USB cable and power brick and keep it plugged in while in use. Having the big USB cable plugged in the back is kinda of annoying frankly.My soldering iron showed up and everything seemed to be working okay when I plugged it in initially - but I quickly realized something was not right. The iron should heat up in 2 seconds, but that clearly was not happening. Also, I noticed the little "heating up progress bar" across the bottom of the screen just keep jumping back and forth clear to the left (it never moved up to indicate the iron was getting hot and reaching its set temp).I went into all the menus and even reset the device, but nothing would make it heat up correctly. The tip did get a tiny bit warm but not nearly up to the temps on the screen. The little progress bar never really got rolling. During temp changing, it popped up, but as soon as the device picked its temp, the temp progress bar showed the device was not heating up. I tried the included 100W power supply as well as other USB-C power supplies I had here but nothing made any difference.The unit arrived with firmware version 1.4 on it, so I thought maybe it needed an update. At the company website it showed there was a version 1.6 so I decided to try installing that. I downloaded the firmware and mounted the iron on my iMac... so far so good.. dragged the .bin file to the device and the tiny screen said "Updating Firmware!" - but sadly it never finished or rebooted. I made a few attempts and each time the unit recognized I had asked it to update the firmware, but never any completion to the update.Unfortunately, the company's website does not give you any means to download previous versions of the firmware (thanks a lot) - so no way to roll things back to version 1.4. I attempted to install the firmware for the HS-02A pen on this one (mine is the HS-02B pen), but that just served to brick the device once and for all. Awesome. This time the iron just rebooted with a bunch of Chinese writing on the screen.. and that's was that. No more mounting the device, no more nothing.So yeah, not real impressed. As mentioned in my video, the little quality control card included with the device was not signed by anyone (despite showing a "passed" emblem which appeared to be printed on the card itself - not added later). I think it's pretty bogus to just toss in a quality control indicator not signed by a human. I sincerely doubt anyone tested this soldering iron before tossing it in a box.Not sure if I'll give this soldering iron another try, but just for wasting my evening I will give it a 1-star review.

This device is my little partner for my first foray into soldering. I wanted something that is easy to understand and operate, while being safe and minimalistic. It heats up almost instantly, and the interface is legible and easy to understand. The ergonomics feel pretty close to perfect for me with the weight being distributed pretty evenly from end to end. Overall, the construction is lightweight while maintaining a premium feel. So far I've used it to find my technique and could see myself buying a second device from FNIRSI if they decide to make another iteration in the future. I highly recommend this product.
