Safety standards: K+A42:K61C, ETL, CE, PSE 3C.

Rated power: DC 5V 2A /24W.

Appearance size/weight: 209.7*31.9*35mm/171g.

Battery specifications: single 21700 8C power battery, capacity 4000mAh (with high and low voltage protection).

Heating element: heating film.

Aluminum plate size: length 75*width 7.9mm.

NTC: R: 100KΩ±5%, B=3950.

Power on/off function: long press the power button for 2 seconds to turn on/3 seconds to turn off. Press the power button for 1S in the power-on state, and the 3 temperature gears can be switched cyclically (170℃-190℃-210℃ Celsius). In this cycle, the corresponding gear light will flash when switching gears.

Temperature gear: Celsius: 1st gear - 170℃; 2nd gear - 190℃; 3rd gear - 210℃, the actual maximum stable temperature is 195-215℃, the actual temperature of each gear meets the requirements of the set gear, and the temperature error range is +5℃ ~ -15℃.

Display mode: 3 LED lights represent 3 gears respectively, the color is white, the gear indicator flashing time: after the gear temperature is selected, it flashes continuously (the flashing frequency is 1 flash per second) and it is always on after reaching the specified temperature (about 90 seconds).

Heating speed: when the machine is turned on and adjusted to the highest gear, the surface temperature of the clamped aluminum plate is greater than 170℃ in 3 minutes, and the actual maximum stable temperature is 195-215℃; the actual temperature of each gear meets the requirements of the set gear, and the temperature error range is +5℃ ~ -15℃.

Low battery display: after the battery reaches 10%, it will become 3 white lights that flash continuously (the flashing frequency is 2 flashes per second) until it automatically shuts down.

Charging protection: When the charging protection voltage reaches 4.2V, the three white lights are always on and charging stops.

Charging time: Charging current: 2A, full charge time is about 3 hours.

Charging display: When the charging signal is detected in any state, the charging mode is immediately entered; the three lights are displayed in a marquee form from bottom to top (circular marquee) until the battery power is full and the white light is always on.

Automatic shutdown function: The timing starts after the machine is turned on, and the machine automatically stops working after 20 minutes (±3 minutes). The timing will not be restarted after the temperature gear is changed during operation.

Normal working environment temperature: -10~50 degrees Celsius.
