You can use the Pinecil to solder a new wire onto itself!

Yeah, one of those tiny barrel jacks. But it doesn’t come with an AC adapter, so you have to find one that matches.

The Pinecil is nice for small projects and accurate work because of its size. It heats up in just a few seconds, and fits nicely in the hand. It’s USB powered, so you need a USB-C PD power source to run it, ideally with a long enough cable that it won’t get in your way.

If I had a need for frequent soldering, I would get one of the high-power models with a small pen, or at least one with a better cable. I like the Pinecil a lot, it’s really good at what I need out of it, but I think it needs some work before it becomes a good professional tool.
