I've found that this USB powered soldering iron is a great tool for electronics. Gets hot very quickly, and obviously very portable and convenient.

WOW! Never knew one existed. Thanks, I need one.
They're cheap too. This is the one I got, at about US$12:
But I see on eBay direct from China they can be half that (probably no package). After I bought it, I bought another. And I also bought "bronze" steel wire tip cleaner, which works a treat, and some flux paste, and some electrical-purpose-solder.
That would probably be much better at doing office computer repairs than my heavy duty pistol grip, two stage trigger, reliable for the last 50+yrs tool that is better for those 10gauge wire.
USB is 5v and 2.5 amp and would be great for delicate work and a smaller guage of solder could be used with precision spotting.
I have a 12v model that has a wall plug adapter that plugs into end of the iron for those delicate spot soldering jobs.
USB is the next stage of power because it is becoming more available and handier than carring a 12v battery around for power.
Yes. I'm not sure how/why 12V has/is becoming obsolete - I was going to post on another thread re Parani BT's, noting that the mains adaptors are 9V (i.e. 12V) but 12V portable power is not that easy these days, without a car battery. I think it is related to Lithium based batteries where the individual cells are multiples of around 1.5V, so why stack 8 or more of them to get to around 12V, when you can get the "equivalent" equipment running on 5V (like the low end of Parani's) or less. These days, all sorts of gizzmos run and charge off USB power. Note that the USB soldering iron was running from the laptop, so for example, one can do emergency field repairs from the laptop.
Richard, I hope it helps put all those scattered parts back together?ÿ ?
I use a USB soldering iron to shape and cut 3D prints. ?ÿ
USB was established as 5v because that is what was the baseline power of motherboards at the time. ?ÿThe standard rechargeable cells at the time were 1.2v, so, there was imeadiate disconnect. ?ÿ12v was just a ten cell battery. ?ÿLithium has two cell main standards, the more popular 3.7 and a less popular 3.2 volts per cell. ?ÿAt least you can buy all kinds of regulators now. ?ÿHigher voltage in a circuit lets you run less amperage to achieve the same work (watts)
