Akkukuumailmapuhallin SDGJ-SDRFQ-DC 18V Solo

For professionals who need heat without the tether, the SDGJ-SDRFQ-DC cordless heat gun delivers a true 550°C maximum temperature from an 18V Li-ion battery platform. Unlike corded units that restrict movement or budget cordless models that struggle to reach soldering temperatures, this tool combines two-stage airflow up to 200 L/min with a fast 5–10 second heat-up, so you can shrink tubing, strip paint, or loosen adhesives anywhere on the job site.

Highlights

• Runs on SDGJ 18V Li-ion batteries (sold separately) for complete cordless freedom
• Two temperature settings: 50°C for delicate work, 550°C for heavy-duty tasks
• Two airflow settings: 100 L/min low, 200 L/min high
• Integrated LED light illuminates the work area in dark spaces
• Ergonomic soft-grip handle reduces fatigue during extended use
• Overload protection safeguards the motor and electronics
• Standard 35mm nozzle compatibility for a wide range of accessories

In daily use

The SDGJ-SDRFQ-DC feels balanced in hand, with the battery mounted low to keep the centre of gravity near the grip. Switching between low and high is a simple two-stage control, and the brushed motor delivers consistent airflow without the lag found on cheaper cordless heat guns. The LED light is a practical addition for working inside cabinets or under dashboards. Because it accepts standard 35mm nozzles, you can use deflectors, concentrators, and reflector nozzles from your existing kit.
