Looks interesting, especially USB-C input. There's a TS80 (and TS80P) which does Qualcomm Quick Charge (and the P for USB-PD) USB-C input, but the Pinecil's flexibility of both seems better. The TS80s also uses different tip form factors, so I would need entirely new tips compared to this.
The TS80P also supports Quick Charge in addition to USB-PD, although QC3 limits you to around 18W (versus 30W for USB-PD).
I wonder how the ergonomics on the production Pinecil will end up. I never ended up liking the TS100s feel for soldering, which made the TS80 my go-to iron. The wide tip availability is great, but I'd rather take a limited tip selection and better ergonomics.
I love the idea of using my lab power supply to power my soldering iron. I will gladly take back the space of my soldering station, it's separate power plug and wires, etc. Plus I'll be able to see current draw in real time.
I do this with my TS100 right now, when I'm gonna be running it for long enough that the Ryobi battery, which serves as its steady base, would not have a good time.
The TS100 can show you the input voltage and duty cycle, I wonder if there's firmware that calculates watts...
