Solder anywhere with the FNIRSI HS-03 Cordless Soldering Iron. Featuring a 2600mAh rechargeable battery and Type-C fast heating up to 450°C (842°F), it provides ultra-portable precision welding.
Traditional soldering stations trap electrical engineers and hobbyists at a fixed workshop bench, making roadside automotive fixes or remote field repairs on RC drones completely impossible. This smart, battery-powered heating tool resolves that constraint by delivering complete corded and cordless operational flexibility. Whether you are working off-grid with an internal power cell or plugged directly into a portable power bank, this lightweight device ensures instant thermal recovery without dragging bulky leads or cords along.
Versatile Hybrid Power Architecture: Operates seamlessly in standalone cordless mode powered by its internal accumulator cell, or works continuously while plugged into a Type-C wall adapter or external power bank.
Intelligent Rapid Thermal Output: Features a multi-level adjustable temperature range spanning from 100°C to 450°C (212°F to 842°F), delivering quick thermal response times to match diverse delicate electrical connections or heavier gauge wire solder requirements.
Integrated IPS HD Color Interface: Outfitted with a bright 0.96-inch / 2.44 cm IPS color screen that serves real-time temperature updates and power status metrics directly to the operator, preventing cold joints or overheating issues.
High-Capacity Replaceable Energy Cell: Equipped with a high-drain 2600mAh 18650 lithium-ion battery to extend remote operating windows while supporting swift field swaps to minimize tool downtime.
Ultra-Lightweight Ergonomic Pen Grip: Weighing approximately 61 g / 2.15 oz, the streamlined design replicates the balance of a standard writing instrument, dramatically reducing wrist fatigue during intricate micro-soldering tasks.
