Mark, Was thinking your example needed external power supply. In any case, I’ve been thinking of a new iron for the shop, but maybe instead I’ll use th money for a van portable one.

Standard Chinese product, where there seems to be one reference design sold under a bunch of different brands. They all use TS tips. The differentiators are typically what is bundled with the unit. I can vouch for the one I bought, but I did also buy a beefier tip to go with it. > > The butane iron I referenced is the only one I've ever owned and have never run out of fuel in the middle of use. > > > -MB > >> On Fri, Apr 3, 2020 at 1:02 PM Alistair Bell <albell@shaw.ca> wrote: >> I was thinking more along the lines of this >> >> https://www.amazon.com/YKEY-Programmable-Pocket-size-Soldering-Acceleration/dp/B071K5FNGT/ref=sr_1_9?crid=366871RDEB5JY&dchild=1&keywords=usb+soldering+iron&qid=1585944038&sprefix=Usb+solder%2Caps%2C215&sr=8-9 >> >> Or similar. >> >> My one butane iron never lasted long.
