Quick Verdict
The Pinecil V2 is still the best all‑around portable soldering iron for most people thanks to its USB‑C PD performance, ergonomics, and price.
But the TS101 closes the gap hard — it’s the modern successor to the TS100, now with USB‑C PD, a better screen, and improved power handling.

Power & Portability
This is where the TS101 finally catches up to the Pinecil.
Pinecil V2

- Also supports DC barrel
- Extremely flexible for field repairs
TS101
- USB‑C PD (20V recommended)
- Also supports DC barrel
- More stable at high temps
- Slightly better power regulation
Both are now equally portable — the TS101 no longer suffers from the TS100’s DC‑only limitation.
Firmware & Customization
Both run IronOS, giving you:
- Custom presets
- Motion wake
- Sleep timers
- Detailed tuning
- Open‑source updates
The TS101’s larger screen makes the menus easier to navigate, but functionality is nearly identical.
