the unit itself is fantastic, heats up in less than 15 seconds, onboard digital temperature precision is fantastic. my only issue so far has been that the power supply connection is faulty. i first noticed sometimes when i picked up the unit to start using it the temperature seemed to have dropped rapidly and was unable to solder until i put the cable in a better position. i have tested the cable on other devices with the same DC port and power requirements and their power flickers on and off with the slightest movement of the cable connection. i tried the unit with an alternate power supply i have and the issue stopped happening. so in troubleshooting i have found that the unit is great but the power cable needs replacing with a quality one (which i fortunately already have but many people probably don't).

I love how versatile this iron is! There's a bunch of tips available and you can power it from almost anything. I have an Anker 65w GaN Prime wall charger, a Goal Zero battery bank, and I even found an adapter that lets me use my laptop charger (Dell has a 7.4mm barrel connector and the iron needs a 5.5mm x 2.5mm barrel connector). The included cords are all soft silicone for heat resistance. I travel with tools alot, so being able to use my laptop charger (which I always have to carry anyway) is really nice as I can save weight and space not having to carry a dedicated power supply. It's ultra compact and lightweight compared to the butane iron I've been using. I no longer have to decide whether to take the butane one or not. This one is so small I can always take it. It's also superior to a butane iron in that you can have it in checked luggage. It's much better for the smaller detailed soldering that I often find myself doing. Butane irons can certainly dump a lot of heat into your work, but that's not always what you want. I will say, the thermal mass is not as good as a full size iron or even a butane iron. It can sometimes take a bit to get the solder to reflow. But, it's good enough to get the job done in a pinch. Using the DC barrel jack with a laptop power supply or the included one definitely yields better performance than USB-C, but I found running it off USB-C to be perfectly usable. Running it off my Goal Zero battery bank, it drew about 52w when heating. It draws >1w when idle. With the Sherpa 100AC at a full charge (≈95Wh capacity) you could work for several hours.

This guy can work wherever you need it! I am a field service engineer and often need to solder something in the area where the power outlet is far away. This soldering iron can be used with a power bank in the pocket. I got a 30000 mAh power bank and I am really independent from power outlets now.
It comes with one tip, and this tip is too small. Different tip sizes are available though and well as many accessories. However, when I got everything I need, it was costly...
What is really missed is a holder for iron and all accessories which would allow to work without table or flat surface around. I would love to get something like a holster where I could put the hot iron while I do not need it. The provided soldering stand is not suitable and actually does not hold the iron reliably. Also, I could have a magnet to be attached to a steel surfaces.
Bottom line - it is great but costly solution if you need to work with electronics and electric far away from power outlets.

Saw this little iron on several YouTube reviews and just had to have one. I can't stand to wait for an iron to heat up when I need it. This unit certainly fixed that problem. Great little iron but prefer to use my Handskit T 12 to this and it was less than half the price.

I also have the original version, T100. I love these irons so small wire work and component soldering. My only real beef is the stiff power cable that I wish was silicone instead of semi soft plastic. I love both my T100 and T101 and I would recommend them to anyone doing component soldering.
