Pinecil soldering iron
By: jarkmanA great cheap tiny soldering iron. It'll run off USB-C (if it can give it 20V) or from DC into a barrel jack. I usuually run it from the mains adapter below, but I also have a USB power bank that can run it.
In a custom 3d printed case by Drew Batchelor
With a nice bendy silicone USC-C cable
And a UGREEN CD216 GaN charger, which can do the 20V 3A that will keep the Pinecil happy.
