9-20V working voltage range for broad compatibility with common power sources. OLED display provides clear, intuitive status information at a glance. Type-C interface supports PD and QC fast charging and works with power banks and other USB-C power sources. Power output is adjustable from 18 to 100 W with fine-tuned voltage/current control. Intelligent temperature control delivers fast heating (2-5 seconds), precise temperature regulation, quick return to set temperature, and an optional sleep mode. Note: slight color variance in appearance may occur but does not affect performance. Use scenarios: - Field work: connect to a PD-enabled charger or power bank to power heating tasks or a compatible tool on site. - Desktop repair or prototyping: use the 18-100 W adjustable output to match tool needs while monitoring status on the OLED. - Portable projects: rely on USB-C PD sources for operation anywhere, with automatic sleep mode to save energy when idle.
