Key benefits Fast, reliable heating: 1.65W output reaches the set temperature in seconds, reducing wait time and improving workflow. Precise temperature control: 220400 degrees Celsius adjustable range with a clearly marked knob lets you set and repeat the exact temperature you need. Instant status feedback: transparent housing lets you see the heating indicator light at a glance, so you always know when the device is active. Flexible power options: DC5.5*2.5 power jack accepts DC12V24V lowvoltage input so you can use common lithium batteries or a laptop power supply for safe, portable operation. How this solves problems Eliminates long preheat delays so you can complete timesensitive repairs and tasks faster. Reduces the risk of overheating components by providing an accurate, repeatable temperature range. Improves safety and convenience with visible indicator light and lowvoltage power input. Enables work away from fixed power sources by supporting battery or laptop power supplies. Main features Power: 1.65W power output for fast heating performance. Temperature range: 220400 degrees Celsius, adjustable via a marked control knob for straightforward, precise setting. Visibility: transparent color housing exposes the heating indicator light for easy status checks. Power input: DC5.5*2.5 power jack compatible with DC12V24V supplies; can be powered directly by lithium battery packs or laptop power supplies. Compatibility and performance notes Works with standard DC5.5*2.5 adapters and 12V–24V lowvoltage sources commonly used in portable electronics and field kits. Lowvoltage operation increases safety for mobile and onsite use while maintaining rapid heatup performance. Marked knob simplifies temperature selection and repeatability across projects. Typical applications Onsite electronics and troubleshooting where quick heatup and portable power are required. DIY and prototyping work that benefits from accurate temperature control and immediate visual confirmation of heating status. Field service, hobbyist soldering, or smallscale assembly tasks using battery packs or laptop power supplies for power. What to expect Fast warmup and stable temperature control between 220 and 400 degrees Celsius. Clear visual feedback through the transparent housing and indicator light. Simple, safe power hookup via a DC5.5*2.5 jack using DC12V24V sources such as lithium battery packs or laptop power supplies.
