How the points were given
Each iron is scored on performance, build, value, safety and warranty, with the weights published on our How We Pick page. The Beizkna and Fanttik listings state auto-sleep features, so they carry the safety points here, and none of the listings states a UL, ETL or CSA listing. The Beizkna listing gives a clear warranty term.

Buying guide: the best cordless soldering iron with heat settings
Heat settings
A knob with marked levels works when you solder the same joints often: the Fanttik tail knob gives 6 levels from 390 to 840 F. A display with fine steps suits varied work: the Beizkna adjusts in 5 C steps from 392 to 932 F with an LED display and plus and minus buttons. The Berkling flame slider sets heat by eye with no stated range, and the Milwaukee listing states no heat setting at all, so check the listing before you buy. Soldering follows diagnosis: our diagnostics and electrical hub covers the meters that find the fault first.
Battery and runtime
The Beizkna and the Fanttik run up to 60 minutes at the top temperature in wireless mode, on 3200 mAh and 2600 mAh, and switch to 16 W wired mode over USB-C when the battery runs low. The Berkling skips the battery entirely and runs up to 90 minutes on a butane fill, refueling in about 20 seconds. The Milwaukee is tool-only, so it needs an M12 battery and charger you already own.
Tips and kit contents
C210 tips fit the Beizkna and the Fanttik: the Fanttik includes 4 and the Beizkna 3, plus a desoldering pump, 20g lead-free solder wire, tweezers, a USB-C cable, a tool box, 2 sponges, a stand and a base in its 14-piece kit. The Berkling includes 2 1.6mm conical tips and a mini wrench for hot tip removal. The Milwaukee listing states no tips, so check what you already own before the first joint. Heat shrink tubing also needs hot air, so see the best cordless heat gun for heat shrink for the hot-air part of the job.
Cordless or corded
Cordless wins when the car sits away from the bench: the Beizkna and the Fanttik work wireless and switch to wired mode over USB-C. Butane wins furthest from power: the Berkling needs no outlet and no charged battery. If you already own M12 batteries, the Milwaukee tool-only iron adds no new charger to the shelf.
Use rated jack stands on solid ground, wear eye protection with power and air tools, keep fuel-burning equipment out of a closed garage, and follow the manual for every tool. Read our Safety Disclaimer.
Garage Fit Check
- Check the heat range against your joints: the Beizkna reaches 932 F and the Fanttik 840 F, while the Berkling lists no range and the Milwaukee lists none either.
- Count the runtime: the electric irons run up to 60 minutes at the top temperature, the Berkling up to 90 minutes per fill.
- Store the butane iron away from heat and use it in a ventilated space: it carries an open flame.
- Confirm the Milwaukee battery: it is tool-only, so an M12 battery and charger must already be on your shelf.
- Keep the kit together: the Beizkna tool box holds the iron, tips, pump, solder wire, tweezers, cable, sponges, stand and base.
FAQ: garage tools
What heat setting should I use for wiring?
Match the iron to the joint: the Beizkna adjusts in 5 C steps from 392 to 932 F with an LED display, while the Fanttik gives 6 levels from 390 to 840 F on a tail knob. The Berkling sets heat with a flame slider and lists no range.
How long does a cordless soldering iron run on a charge?
The Beizkna and the Fanttik each list up to 60 minutes at the top temperature in wireless mode. The Berkling lists up to 90 minutes per butane fill, and the Milwaukee listing states no runtime.
Do I need a kit or just the iron?
The Beizkna 14-piece kit includes the iron, 3 tips, a desoldering pump, 20g lead-free solder wire, tweezers, a USB-C cable, a tool box, 2 sponges, a stand and a base. The Milwaukee is tool-only, so the battery and charger come from your own M12 kit.
Can a butane soldering iron replace a battery iron?
The Berkling works as an iron, a mini heat gun and a micro torch, refuels in about 20 seconds and runs up to 90 minutes per fill. It lists no temperature range, so you set heat with the flame slider rather than a display.
What tips come with these irons?
The Fanttik includes 4 C210 tips and the Beizkna 3 C210 tips. The Berkling includes 2 1.6mm conical tips and a mini wrench, and the Milwaukee listing states no tips.
