Same thing. Runs off an external power supply and heats up to 400C. 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.
