Cordless Battery Soldering Iron with USB-C Charging and IPS Display

Description

The FNHS03 is a cordless soldering pencil designed for anyone who works away from the bench or needs to work without cables getting in the way.
The built-in 2600mAh battery is removable and replaceable, which extends the working life of the tool and lets you keep a charged spare cell in your bag during longer sessions. Charging is over a standard USB-C port, the same one used by modern smartphones, so no dedicated adapters are needed.

The tool supports two separate power modes: standalone battery or direct USB-C, switching from one to the other without any break. It reaches working temperature in just 7 seconds, cutting the dead time between one job and the next.

Thermal control is handled by a PID algorithm that keeps temperature swings under load to a minimum, so the iron stays stable even during long soldering runs on pads with high thermal mass. Adjustment is in steps of about 0.5°C, with 5 preset levels on a quick slider for changing thermal profile without stopping the work. The range covered runs from 100°C to 450°C, spanning everything from delicate soldering of sensitive components up to applications that call for higher temperatures.

The 0.96″ colour IPS display shows the set temperature, the actual temperature, the power mode and the battery state in real time. Auto-sleep and standby are configurable: the FNHS03 goes into rest mode after an idle period that can be set between 0.5 and 60 minutes, cutting consumption and preserving the tip. The silicone grip is ergonomic and works for both right-handed and left-handed use, with the button logic adapting automatically.

The tips supplied in the box are: a K type (knife blade), alongside an I (extra-sharp) and an IS (bent hook), all from the F210 series with a 2.10Ω core that gives a fast, even thermal response. The FNHS03 comes complete with a hard carry case and a USB cable for charging, making the kit self-contained and ready to use straight out of the box.

Typical applications include electronics repairs in the field, servicing boards in racks or in places where a corded iron would be awkward, lab teaching, maker prototyping and DIY work on consumer electronics. Real battery life, precise thermal management and portability together make the FNHS03 a versatile tool for the professional technician and the advanced enthusiast alike.

Heats up in 7 seconds, 100–450°C range and 5 quick-adjust levels

Removable, replaceable 2600mAh cylindrical battery, dual power mode — standalone or over USB-C — working temperature in 7 seconds and a 100–450°C temperature range. Precise 1°C adjustment with 5 preset levels, PID control and configurable auto-sleep to preserve the tip during breaks.

Five preset thermal profiles, switched on the fly without stopping the work

Rotary collar for instant selection between 5 preset temperature levels, so you can change thermal profile without interrupting the soldering.
Precise control with PID stabilisation and an IPS display showing the working temperature in real time.

---

Replaceable 2600mAh battery for soldering without interruptions

Removable 2600mAh Li-ion battery, replaceable in three simple steps: unscrew the cap, fit the new cell, screw it back. The dual power mode — standalone battery or over USB-C — keeps the iron working without breaking off the soldering session.

---

Programmable standby and sleep for energy saving and longer tip life

Sleep configurable from 0.5 to 60 minutes, standby from 1 to 60 minutes and sleep temperature adjustable between 100°C and 200°C to preserve the tip during breaks.
The on-screen menu allows full customisation of the power settings, including temperature calibration and reset to factory data.

---

PID control with a stable temperature curve up to 450°C and no swings

Advanced PID thermal control chip that removes temperature fluctuations under transient load, giving a stability curve clearly better than that of conventional tools. Ideal for precision soldering on semiconductors, SMD components and high-density circuits.

---

Portability with a protective cap, temperature step switching and updatable firmware

Safety cap so it can be carried in a bag or rucksack without risk, continuous-slider temperature adjustment for precise step switching, and firmware update support straight from the system menu, to keep the tool current over time.

---

Three power modes: standalone battery, USB-C power supply and power bank

Three working modes: fully cordless on battery for field work, powered over USB-C from a mains adapter for continuous bench use, or connected to a power bank for maximum portability without giving up continuous power.

---

Compact aluminium body with silicone grip for the best control and comfort

Silicone grip with an ergonomic design that keeps hold secure even during long working sessions.
The compact, balanced profile of the aluminium body reduces hand fatigue and gives precise control over the tip.

---

Interchangeable precision tips with quick fitting

Tip range with a 2.10Ω heating core and 6.6cm length, interchangeable without tools. Three geometries included: knife blade (7.7×2.7mm) for soldering on wide pads, extra-sharp (6.6×0.6mm) for fine components, bent hook (6.4×0.4mm) for SMD parts and connectors in tight spaces.
