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. Probably better ones now and that’s a good option.
