HGLRC RC1 is an affordable soldering pen suitable for occasional repairs and field soldering. The RC1 soldering pen is powered via a USB-C connector through a power bank supporting fast charging (PD, QC) or directly from a 3-6S Lipo battery. All soldering pen data is displayed on a small 0.91" OLED display. A nice feature is the integrated beeper that alerts you to changes in the soldering iron's status. The temperature is adjustable in the range of 50-500°C. A microprocessor with an intelligent algorithm takes care of maintaining the desired temperature. The soldering pen has a low voltage alarm. This protects the power supply battery from over-discharge. With a power output of up to 60W(depends on the supply voltage), the heating is very fast. The soldering pen comes in a handy C210 tipped case.
