Great little unit, fully charged it before first use. Some of these welders need to charge up for your first weld to get a good weld not this one put the cart in and start welding right away. I found for my welding purposes setting 03 is perfect, this works great on old carts that are less tan and more brown that other welders will not work with or one you’ve spaced out on and found later. Heat up is great I’m in about 2 weeks on first charge. I weld daily and only one bar has gone out on the digital power meter pretty cool design maybe get three weeks or more on a charge. Charging is a breeze. So nice I bought it twice. Weld away fellow welders.

This is the first cordless soldering iron I have used so if some of what I have to say may be par for the course for such devices and not special or unique to this product.This iron is only 9/16" in diameter. The iron with the conical tip installed measures 6 3/4" long. With the conical tip installed it weighs only 1.6oz (46g) with the cap, 1.4oz (39g) without the cap. It really feels like a marker pen in hand.The iron has two visible indicators. One is a display that shows the current battery charge and the heat setting. The other is a blue light ring around the power button.To avoid accidental turn on, 5 quick presses of the power button are needed to turn on the iron. When the iron is on, the blue ring flashes and subsequent button presses will also generate flashes. Triple clicks cycle the iron through 3 heat ranges. The current heat range will be displayed.Holding down the power button heats the tip to the range that has been set. This takes no more than a handful of seconds and the iron is usable. Letting go the button will start the cooling process.Double-clicking the power button keeps the iron heated without having to press the button to activate the heating. In this mode the blue ring stays on with a breathing pattern. The heat range is set to 3.0, basically equivalent to the 03 range. I prefer to use the iron in this mode for a longer solder task so that I don't need to keep the power button held down.The battery life is kind of impressive. The iron can be charged from a basic 5W USB charger or from a high wattage USB-C charger. The iron is charged through the USB-C port on the end of the iron. The iron can be used while charging as long as there are at least two bars of battery life displayed.With the battery fully charged I used the iron to solder a mechanical keyboard PCB, a small project that requires making approximately 130 solder joints. This didn't take too long but when I was done the battery indicator still had 2 bars. I might have been able to work through two PCBs at this rate before recharging.When the iron is unattended for 10 minutes it will put itself to sleep.5 clicks of the power button also turns the iron off. Pressing the power button once after power is shut off will not activate the blue ring. That's a surefire way to verify that the iron is indeed off.I have used only the conical tip so far. The other angled tip will be useful for tasks in the future.The iron also comes with an accessory pouch, a USB charge cable, a thin fold out metal stand and a small sponge. I don't need the sponge as I have my own tip cleaning method already but the lightweight stand is useful. To avoid heating up the stand itself, I set only the body of the iron onto it, not any part of the iron's hot metal.Overall I am very satisfied with this cordless soldering iron. I have been using a Weller solder station for years, and while such a station may feature greater heat range adjustment and can keep going for hours, it is not at all portable nor really convenient. For smaller jobs like a keyboard I will happily use this cordless iron and keep the solder station for heavier duty work.

This small portable soldering iron is my first soldering iron ever. I’ve needed and wanted one of my own for years but could never decide on getting one that was corded or one that is battery operated. The reason for my delay is that I used to sell high-end consumer electronics years ago and part of the training for that was to know the differences between corded power and battery power. one of the biggest differences is quarter power utilizes a lot of the power from the wall, so therefore it doesn’t have to limit how it uses that power. While on battery power, the unit has to be efficient with the limited power the batteries providing. But that was years ago now what we have is batteries that are both powerful and efficient and so therefore the power is really just limited to the design. This pen is super powerful once I powered it on it took seconds before I smelled that familiar smell of hot iron Not a minute but seconds maybe 30 seconds and it smelled ready to go. It has a nice display to tell you your battery power and your setting.This soldering pen while really useful and really strong still isn’t the same as using a corded one you have limits due the battery and size on the size of job that you can do. Well, you won’t be able to probably do all day work at your workbench on large jobs with this. You should still be able to get by doing spot repairs on the go and even doing some small and moderate size builds maybe a guitar pedal or even your Arduino or raspberry pi unit that you’re trying to build. I am building a raspberry pi unit or two and this is perfectly sized for the job.This pen gets hot, so be very careful and use the included stand that folds to hold the pin up while it’s either not in use or cooling after you’re done because it will take several minutes for it to cool. Read the instructions even though they are translated from probably Chinese very poorly in English if you’ve use a soldering iron before you’ll at least get the gist of what is being conveyed to you and the instructions. if you’ve never used a soldering iron before then read the instructions and know that this device does get hot and you can’t just let it burn dry. You have to be using it or switch it off otherwise you can ruin the probe with the dry burn. The power switch is something to get used to, but I get why it takes five clicks to turn this on and off, safety. This device is safer than my stun pen that I have. That has a slide switch that can slide with the lightest of touches and is ready to fire in my pocket by accident, while the 5-click switch will make it harder for small children, pets, and your pockets to activate by accident. That makes this safer than my taser pen to carry.The pen is super portable. It comes with a little tote bag that requires taking the probes off and storing them in the cap as like they were shipped, which I'm not a fan of because it could allow lint to get into the conductive end where the probes screw in. But I found a great solution with an aluminum box that wasn't being used that my chainsaw chain came in and it is a perfect fit and more secure. If you did need to travel light and don’t have space for putting it in the tin like I did, pictured, then the pen can travel with a probe attached and in a pocket but it doesn’t have a pocket clip on it.
