Frequently Asked Questions
Q: How long does the USB soldering iron take to charge fully?
A: Charging time varies depending on the power adapter used, but with a standard 5V USB adapter and the included Type-C cable, the 600mAh battery typically charges in approximately 1–2 hours.
Q: Can I use this USB soldering iron for PCB and circuit board work?
A: Yes! The lower temperature gear (300–340°C) is ideal for precision soldering on PCBs and small SMD components, while the higher gears are suited for thicker wires and larger joints. The slim 16mm tip provides good control for detailed work.
Q: Does this soldering iron work while plugged in, or only on battery?
A: This cordless soldering iron is designed to be used on its built-in rechargeable battery. Charge it fully before use, and the auto-sleep feature helps maximize battery life during your session.
Q: Is replacement solder wire compatible with this iron?
A: Yes. The set includes solder wire to get you started, and standard rosin-core solder wire available at any electronics shop is fully compatible with this iron.
