Solder anywhere with a swappable 18650 cell, USB-C backup power and a 7-second heat-up. Built for quick fixes and fine work away from the bench.

## Pricing

- **Price:** $112.00 (inc GST) — $101.82 AUD, exc GST

## Availability & dispatch

- Available with a lead time — expect dispatch between Oct 19 and Nov 03.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE11103:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/CE11103:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

A pocket-sized, battery-powered pen iron for jobs where setting up the bench station is overkill: a header that needs re-seating, a lifted wire on a robot, or a repair out in the field. It heats to working temperature in about 7 seconds and holds it there with PID control.

Most portable irons need a power bank on a cable or a butane refill. The HS-03 Plus has a removable 2600mAh 18650 lithium-ion cell inside the handle, so it's truly cordless. When the cell runs low, plug into any USB-C source and keep soldering, or swap in a fresh cell. Because the battery can be replaced, a tired cell doesn't mean a dead tool.

At 10W maximum, it's designed for precision work: small through-hole joints, SMD parts, tinning wires and touch-ups. The F210-series tips use a low-resistance 2.1Ω heater core for quick thermal response on small parts. For large ground planes or heavy-gauge wire, a higher-power iron such as the [FNIRSI HS-02A (100W)](https://core-electronics.com.au/hs-02a-100w-smart-soldering-iron-with-tool-box.html) is a better fit.

### Features

- Work anywhere with true cordless operation, powered by a removable 2600mAh 18650 cell
- Never stall on a flat battery: switch to corded USB-C power and keep working
- Start soldering in about 7 seconds with rapid heat-up
- Get consistent joints on sensitive parts thanks to PID temperature control that limits drift under load
- Cover delicate SMD work through to higher-temperature jobs with a 100–450°C range
- Jump between common settings using five quick-select temperature presets, with fine adjustment in 1°F steps
- Extend tip life and save battery with configurable auto-sleep (0.5–60 min) and standby (1–60 min)
- Check temperature, power status and mode at a glance on the 0.96" colour display
- Comfortable for either hand, with left- and right-hand modes that remap the buttons
- Light (about 134 g) with a silicone grip, so longer handheld sessions are less tiring
- Ready for most jobs with three tips included: knife (K), extra-fine (I) and bent fine (IS)
