FNIRSI® HS-03 Cordless Soldering Iron, 18650 Removable Battery, USB-C, 212–842℉

Fnirsi HS-03 Cordless Soldering Iron

This is a great cordless battery soldering iron. Very quick to heat up, accurate display of live tip temperature, and see its temperature recovery. In most cases, I only ever need to solder a couple of joints. This is the perfect compact tool for the job. So much better than gas burner type compact irons, where you had no idea and no control of the temperature.

Great soldering irons and tools! <3

I needed a portable and compact soldering iron with fine and lasting tips. First sceptical I ordered the USB-C iron and the new! 18650 (great choice!) battery powered one and they are great! Keep coming up with more awesome products! :)

FNIRSI® HS-03 Cordless Soldering Iron - 5 Stars!

I picked up the HS-03 as a second iron to complement my bench Weller soldering station — something convenient for quick jobs, delicate work, and tasks that need to happen away from the bench. It's exceeded my expectations on every front. Build & Design The rechargeable, swappable 18650 battery is a real win. It's easy to pop out and replace, holds plenty of charge for a session, and recharges quickly over USB-C. In hand, the balance is excellent — it genuinely has a professional feel, not the cheap or top-heavy feel I half-expected from a cordless iron. Performance Heat-up is essentially instant. The digital temperature display means I always know exactly what I'm working with, and the fine tip is precise enough for delicate work. All three included tips performed equally well — no weak link in the kit. Standout Features A few things really stood out: Instant heat-up and the digital display Easy-reach temperature buttons positioned right where my hand is already holding the iron — adjustable on the fly without breaking my grip A dialed-in temperature range rather than fixed presets, so I can fine-tune exactly where I want to be Overall build quality and the included case/accessories — everything feels well thought out and well put together Gripes Honestly, none. I've used it for a range of quick projects and haven't hit a limitation yet. Verdict: 5/5 This has become my go-to iron for quick work. It's good enough that I'm now looking seriously at your other products — the DPS-150 Mini DC Adjustable Programmable Power Supply is on my radar next.
