A look inside a portable soldering iron that uses a vapour style power supply.
After it was suggested, I bought one of these hybrid units that are based on the USB style soldering elements and common vapour power supplies. If you already carry a vapour power supply then it means that all you need for spontaneous soldering is one of the tubes with a single bit in it and some solder spiralled around it.
The unit heats very quickly and is quite handy for spontaneous wire removal from PCBs. That's why it appeared on my bench during another video.
To operate it you have to cycle the power button to keep it awake, and adjust the cycle time for thermal regulation based on feel. It's very easy to overheat the tip.
The unit has a lock which can either be enabled or disabled with 5 quick presses of the button. This makes it less likely to be turned on accidentally in a tool kit or pocket.
I've removed the aliexpress link because the seller started price gouging, and I don't tolerate that sh*t. Search for the following keywords instead:- usb portable soldering iron
You can also buy just the bits for your existing vapour power supply. Be careful with the power setting if your power supply can boost the voltage for higher wattage, as excess power may shorten the life of the bits dramatically.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
