When choosing an electronic cigarette with intelligent temperature control function, factors such as temperature control technology, material compatibility, safety performance and user experience should be comprehensively considered. The following is the specific purchasing guide:
Resistance temperature detection (TCR technology)
Principle: Based on the characteristic that the resistance of metals changes with temperature, the temperature of the heating wire is calculated in real time by preset temperature coefficient (TCR).
Advantages: No temperature sensor is required. The temperature is directly estimated based on the change in resistance, with a fast response speed.
Compatible materials: Supports common heating wire materials such as nickel, titanium, and 316 stainless steel. Some high-end hosts support custom TCR.
Temperature sensor monitoring
Principle: Place the sensor near the heating wire to directly sense the air temperature.
Advantages: More accurate measurement and reduced resistance estimation error.
Applicable scenarios: Scenarios with extremely high requirements for temperature control, such as high-power atomization.
Temperature control range and accuracy
Range: The temperature control range of mainstream equipment is 100-300℃. It is recommended to choose equipment that supports 200-235℃ (in compliance with the new national standard requirements to avoid the generation of harmful substances at high temperatures).
Accuracy: Prioritize the selection of equipment with a temperature control error of ≤±5℃ to ensure temperature stability.
The compatibility of heating wire materials
Nickel (Ni200) : It has a high TCR value and a fast temperature control response, but it is prone to oxidation and needs to be replaced regularly.
Titanium (Ti) : It has strong corrosion resistance, stable temperature control and is suitable for long-term use.
316 stainless steel: It has good comprehensive performance. Its temperature control accuracy is slightly lower than that of nickel and titanium, but it has a longer service life.
Host chip support
Supported materials: Prioritize equipment that supports nickel, titanium, and 316 stainless steel. Some high-end hosts support custom TCR.
Chip performance: Select devices equipped with high-performance chips (such as the DNA series) to ensure the accuracy of the temperature control algorithm.
Safety protection function
Overcharge protection: Prevents battery overcharging and extends battery life.
Short-circuit protection: To prevent equipment damage or safety accidents caused by short circuits.
Overheat protection: Automatically reduces power when the temperature exceeds the set range to prevent dry burning or oil explosion.
User experience optimization
Convenience of operation: Choose devices that support one-click temperature control switching or APP adjustment to simplify the operation process.
Battery life: It is preferred to choose devices with a battery capacity of ≥1200mAh. Fast charging function is even better.
Taste consistency: Devices with precise temperature control can ensure the stability of the smoke taste and prevent taste changes caused by temperature fluctuations.
Brand and Certification
Legitimate brands: Choose well-known brands such as Relx, Ejiate, and JOUZ to ensure product quality and after-sales service.
Compliance certification: Give priority to choosing equipment that has passed the new national standard (GB/T 41721-2024) certification to avoid purchasing "three-no" products.
Actual measurement verification
Temperature control accuracy: After receiving it, verify the temperature control accuracy through actual measurement, such as using an infrared thermometer to measure the actual temperature of the heating wire.
Smoke texture: Test the consistency of smoke density and texture by using e-liquids with different VG ratios.
Long-term cost considerations
Atomization core lifespan: Select equipment with an atomization core lifespan of ≥2 weeks to reduce consumable costs.
Battery durability: Prioritize batteries that support over 1,000 charge and discharge cycles to extend the service life of the equipment.
Yijiate PEAK
Temperature control technology: Dual-frequency temperature control chip, supporting three levels of adjustment of 12/15/18W.
Performance highlights: When the 0.6Ω core is paired with 15W, the uniformity of nicotine release exceeds that of competing products by 37%. When combined with 80%VG e-liquid, the fruit flavor restoration rate reaches 99%.
Battery life: With a 1200mAh battery, it can be used continuously for two days when fully charged.
JOUZ 12
Temperature control technology: "chip-level" precise temperature control, supporting mainstream cigarette cartridge specifications.
Performance highlights: It can be used continuously with 12 cartrpers, and the taste consistency is high.
Design advantages: Minimalist square and round design, convenient operation.
SPACEMAN SP40000
Temperature control technology: Equipped with a 3D curved digital screen, it supports 4 levels of ice temperature and nicotine adjustment.
Performance highlights: 40,000 suction cycles, meeting the requirements for long-term use.
Intelligence: Supports APP control, allowing for customization of smoke volume and taste parameters.
