This soldering iron works very well. It's easy to use.

It seems if you spend much time making stuff there is always a point where it is inconvenient to drag stuff back to the bench to solder something. The Hakko is an excellent utility tool for making a few solder connections. It heats quickly and holds its heat well. Battery life meets specifications and the price is very reasonable.

I grabbed one of these when the first batch appeared, right before leaving town for an extended business trip. So glad I did. It heats up quickly, offers two temp settings (determined by battery type used), and is not nearly as awkward to handle as I had feared it would be due to the weight of the batteries. And I just finished soldering up a board whilst sitting on the beach. Re-read that last sentence, and then pick up one of these.

This iron is awesome... very easy to handle, not too much weight or too little. The tip is the perfect size.

The Hakko FX-901 Cordless Soldering Iron is a great tool. It sits beside my Hakko FX-951 Soldering Station so if I only need to solder one joint I use it instead. It is well balanced and the included T11-B cone tip is just the right size. I can't say enough good about it.

I dig this wire free lil animal. perfect for the price you can't go wrong. my only bitch would be the fact it only has two tip options. thoughts and prayers!

I purchased this as a better alternative that butane portables. So far, so good - very nice iron in a neat little package. Have not used it long enough to drain a battery set or anywhere other than the benchtop. But, it's looks like it's going to be a pretty good portable.

Very nice and fine tip - I wonder if it will provide ample heat for joining fatter gages perhaps with a little breeze. It is an on-off scenario - heat-up is fairly quick, but not "instantaneous".

Given a charging port and batteries, it actually probably could be a nice light-duty bench solution.

I've only used this a few times so far so I may run into difficulties down the line, but so far I've been able to solder with both leaded and lead-free solder without issue. The run time on one set of batteries is better than I expected, and the temperature is much better too (both as advertised :P).

I'm very happy with this soldering iron so far, and hope that it lasts for some time. I love that it has replaceable tips because my last soldering iron's tip broke and it wasn't replaceable, but it was a cheap iron anyway. I would definitely recommend this to a friend if I had one that needed a small portable soldering iron in the future.

Una de las mejores herramientas que he usado.

I'm pleased with this purchase, but item description says: "Wide selection of tips available" I can't find any on this site... Tried to google it and found two types each for $20+shipping, At this price i would prefer to just buy second one :)

Pros: Heats up quickly and can power tip for a fair while. Easy to use and get in akward angles Con: I find the tip too pointy for electronic boards pads - a bit wider would be great.

All in all, great product

I bought this soldering iron so I could carry it in my backpack to the middle school where I teach engineering and robotics. I was expecting it to be a poor substitute for a "real" soldering station, useful just for quick fixes to student projects. Instead, it turned out to be awesome! My students and I were able to easily solder all of the headers onto a set of Arduino shields, and still had plenty of battery life left. It heats up extremely quickly, much faster than my soldering station. If it didn't use batteries, I would switch to using it for all of my soldering needs. But it works fantastic as a portable, cordless soldering solution.

I was skeptical - a soldering iron powered by AA batteries - right. But this thing is impressive. I assembled a small sound-activated kit over the weekend - about a two hour job powering off and on as needed. Checked the batteries afterwards and still showed 5.9 volts. The heat-up time was very good, just a few seconds. This beats the heck out of my portable butane soldering iron.

I recently used this to solder some breakaway headers to protoboard, which it handles fine. I also tried soldering a 22awg solid ground wire to several other wires, all sinked against the protoboard and it bogged down, which is understandable for ~5W. The real value of this iron is that it takes up very little space, can be set on top of other things on a crowded workspace (!!), and uses common batteries. The cap is some sort of ceramic, so the iron can be capped while still hot. This also forces the switch off.

Note: I used Eneloop AA NiMH from Amazon, ~$20 including a charger, and the iron was plenty hot enough for small gauge wire using lead free solder. Heat up time = 30-40 secs

I have not had a chance to use it in any practical manner yet besides putting batteries and tinning the iron but overall it performed well and the tip looks like its pretty good quality. I just really like the fact that the batteries are replaceable. I paid over 3 times this much for a cordless rechargeable and when the batteries went up (because the charger was simply a transformer with a diode) I was out of luck. It was quite involved to remove the batteries and replace them. So far I think this is a really good value for the price.

Heats faster than I expected. Not too heavy.

I should have taken the advice that beginners should start with the cheapest solder iron available and leaded not lead-free solder. It appears that this iron does not get hot enough to work with lead-free in a reasonable time frame. And you can just about forget about re-working anything, unless perhaps you can get a flux pen. I have been unable to find out where to get one locally. I am a complete beginner, so I don't really know how it is supposed to go, but it seems to take 10 times longer for each joint than the tutorials say. I have tried alkaline as well as rechargeable batteries. I have done one small project and am half through another, but it is painfully slow with any kind of battery, and they don't last very long. Seems the red light stays on even if the batteries are not giving the iron not enough power to solder any more. Description should have warned about unsuitability for lead-free, imho. Might be more acceptable for leaded.

works very well and is very useful when you want to solder only one or two thing.

No cords so you don't have to worry about that. Though you will need to buy specific batteries for it. It also struggles with RoHS soldering with high heat-sinking items if using rechargeable Ni-MH. But all around with leaded solder handles well. Did a little SMD soldering with it and it worked well. Took it to work and did soldering there with it for a bit worked decently under stress even with using RoHS solder. In the end I do want maybe a custom bat-pack for it that gives it the juice to handle for longer periods and handle RoHS better.

I’ve been using mine for quite some time now and it is awesome, can’t praise this piece of kit enough!

Very handy

Not a high professional tool but it does it's job perfectly. No wires around and warms up in just a few seconds from switch-on. My preferred solder when I need the soldering work done without wait time. Not adapt for long soldering sessions because the batteries are drained quickly. Very useful if one need to do the work out-door and not in the lab.

Just what I needed!

I use expensive irons at work and this is no match for them. But it does work well for a battery powered unit. My only complaint is it gets bogged down when soldering to a large ground plane or other thermally large part. Overall an excellent addition to the toolkit!

I've discovered in my 67 years that a devise often works best if it is removed from the marketing package first. Having not been at home since the soldering iron's delivery, I have failed in executing the first step in using the devise. However, within a few days, I intend to remove the soldering iron from the packaging. Then use it when soldering some connections on my outdoor G-scale model train layout. That was the purpose for which I purchased the "cordless" soldering iron. Stay tuned for the rest of the story.

I put off this purchase for a long time, since I already have soldering irons. Now that I have this one, I spend more time tinkering with electronics projects, just because I don't have to clear space, get out the temperature controlled iron, and pack it all up when I'm done (after waiting a long time for it to cool down). Now I just flip the switch, do a little soldering, and turn it off.

It heats up quickly, melts solder quickly, cools off quickly, and is just a really handy addition to my tool set.
