PINECIL Smart Mini Portable Soldering Iron Review

By PINE64 · Updated 2026-09-15

9.0 / 10 · our score

A tiny, open-firmware smart iron that draws its power over USB-C instead of carrying a battery. Plug it into a strong USB-C charger or power bank and it heats fast, with proper temperature control in a pen you can drop in a pocket.

Our verdict

The Pinecil is the best portable iron for people who already live on USB-C. It is not cordless in the battery sense, but paired with a capable power bank it goes anywhere a battery iron does, and with a good charger at a desk it heats and recovers far better than its size suggests. Budget for a strong USB-C power source, because a weak one is the difference between a great iron and a sluggish one.
