Precise temperature control: marked adjustment knob lets you set temperatures between 220–400 °C for accurate work on different materials and solder types. Fast heating and performance: 65 W output reaches the set temperature in seconds, reducing wait time and improving workflow. Wide lowvoltage power compatibility: DC5.5*2.5 power jack accepts DC 12–24 V input, so you can power the tool from a lithium battery pack, laptop power supply, or other compatible DC sources. Visible heating status: transparent housing reveals the heating indicator light, so you can confirm when the unit is active at a glance and monitor operation without guesswork. Practical and safe for portable use: lowvoltage DC operation enables safer field use and convenient connection to common external power supplies. How this solves common problems Eliminates long warmup times with 65 W rapid heating, so you can start work faster. Avoids compatibility issues with fixed AConly tools by supporting DC12–24 V sources. Reduces uncertainty during operation by providing a clear visual heating indicator through the transparent body.
