RF4 RF-S810 USB-C Intelligent Portable Soldering Iron (75W - QC/PD)

Description

The RF4 RF-S810 intelligent portable soldering iron is a high-performance precision equipment specially developed for mobile repair technicians, micro-soldering experts and field service engineers. Designed in an ultra-compact pen-type format, this autonomous tool advantageously replaces bulky soldering stations for all routine operations of solder rework, charging connector replacement, FPC ribbon cable interventions or motherboard (PCB) wiring.

On the electromechanical side, the RF4 RF-S810 integrates an intelligent microcontroller board exploiting Power Delivery (PD 3.0) and Quick Charge (QC 3.0) fast charging protocols via a USB-C port. Capable of developing a maximum thermal power of 75W under a 20V voltage, it embeds a low-inertia integrated resistance heating cartridge. This architecture allows reaching the set temperature (300°C) in less than 5 seconds from a cold start. The body of the device houses a high-definition digital screen displaying real-time temperature, applied input voltage and the adjustable setpoint from 100°C to 450°C. A PID regulation algorithm maintains constant thermal stability, even during contact with heat-sink-heavy ground planes.

The chassis is entirely machined from aerospace-grade aluminum alloy with an anodized coating resistant to scratches and flux splashes. Its gripping area incorporates reinforced thermal insulation to maintain a comfortable hand temperature during prolonged use. The RF-S810 features advanced safety functions, notably a motion detector managing automatic entry into sleep mode (Sleep Mode) and automatic safety cutoff in case of prolonged inactivity, thereby considerably extending the lifespan of the tip against oxidation.

Workshop Tip & Usage

To exploit the full 75W power of the RF4 RF-S810 and guarantee instant temperature rise, make sure to connect the device to a USB-C wall charger or an external power bank certified Power Delivery (PD) delivering a minimum of 65W to 100W (i.e. 20V / 3.25A to 3.75A). Using a standard 5V USB-A adapter (5W/10W) will throttle the heating or trigger an insufficient power supply error. To preserve the tinning of the heating tip, systematically apply a drop of fresh solder before putting the iron down and clean the tip using brass wool rather than a wet sponge, in order to avoid repeated thermal shocks.
