Precise temperature control: adjustable 220400 degrees Celsius with a clearly marked knob for quick, repeatable setting. Ideal when jobs require exact heat levels. Fast heating and performance: 65W power output heats quickly and reaches the set temperature in seconds, reducing wait time and improving workflow. Lowvoltage, portable power options: builtin DC5.5*2.5 power jack accepts DC12V24V input. Can be powered directly from compatible lithium batteries or a laptop power supply for safe, onthego use. Visible status and safer operation: transparent housing lets you see the heating indicator light and easily confirm heating status at a glance. Easy to use and compatible: simple knob adjustment, standard DC power jack, and broad voltage range make it compatible with common mobile power sources and field setups. Key specifications Temperature range: 220400 degrees Celsius (adjustable) Power: 65W Power input: DC12V24V via DC5.5*2.5 jack Housing: transparent color for visible indicator light Practical applications Field repairs and mobile service: run from a lithium battery or laptop adapter for soldering and heat tasks where mains power is not available. Electronics assembly and rework: precise temperature control and fast heating reduce heat exposure to sensitive components during soldering or desoldering. Hobby and small craft projects: consistent, visible heating makes it easier to work on model electronics, jewelry, or small heatshrink tasks. What this delivers for you Accuracy: precisely set the temperature you need with a marked knob to avoid overheating components. Efficiency: power and rapid warmup minimize downtime. Portability and safety: lowvoltage input options let you work off batteries or adapters with reduced electrical risk compared with mainsonly tools. Confidence: transparent housing and indicator light provide an immediate visual check of operating status. Includes the listed specifications and functions as described: adjustable 220400 degrees Celsius, marked knob, 65W output, DC5.5*2.5 power jack, DC12V24V input, visible heating indicator through transparent housing.
