Low-temperature environments have a significant impact on the storage and use of electronic cigarettes. Targeted measures need to be taken to ensure the performance and safety of the equipment. The following are the specific precautions and analyses:
The performance changes of e-liquid
Increased viscosity: Low temperatures cause the viscosity of e-liquid to rise and its fluidity to deteriorate, which may lead to a decrease in atomization efficiency, a reduction in smoke volume, and even the occurrence of a "burnt core" phenomenon (the e-liquid fails to timely wet the heating wire).
The taste becomes milder: Low temperatures may inhibit the evaporation of essences in e-liquid, resulting in a weakened taste and aroma.
Battery performance declines
Capacity attenuation: The capacity of lithium batteries will significantly decrease at low temperatures (such as below 0℃), and the battery life will be shortened.
Increased internal resistance: Low temperatures cause an increase in battery internal resistance and a decrease in discharge efficiency, which may lead to the device being unable to start normally or insufficient power supply.
Risk of condensate water
Condensate accumulation: In low-temperature environments, e-liquid vapor may condense inside the equipment due to temperature differences, forming liquid, which can lead to leakage or corrosion of the circuit.
Physical structure risk
Material embrittlement: Extreme low temperatures (such as below -20℃) may cause plastic, rubber and other components to become brittle, increasing the risk of cracking or damage.
Temperature control
Suitable storage temperature: It is recommended to store e-cigarettes in an environment ranging from 5℃ to 25℃, avoiding temperatures close to the freezing point (0℃) or lower.
Avoid extreme low temperatures: If you need to carry the e-cigarette outdoors in cold weather, you can put it in your personal pocket or insulated bag to maintain the temperature with your body temperature.
Battery management
Maintain battery power: Before long-term storage, charge the battery to 40% to 60% to avoid being fully charged (100%) or undercharged (0%), in order to reduce the damage to the battery caused by low temperatures.
Regular power replenishment: If the storage period exceeds one month, check the battery level every 30 days and recharge it to 40% to 60%.
Smoke bomb protection
Sealed storage: Unused e-cartridges should be kept sealed to prevent cold air from entering and causing the e-liquid to condense.
Vertical storage: After opening, it is recommended to place the e-liquid cartridges vertically to prevent the e-liquid from seeping into the airways due to gravity and aggravating condensation problems.
Moisture-proof and condension-proof
Dry environment: Add food-grade desiccants (such as silica gel bags) to the storage container to absorb excess moisture and reduce the formation of condensate.
Avoid sudden temperature changes: When entering a room from a low-temperature environment, do not use the e-cigarette immediately. Wait for the device temperature to rise back to room temperature to prevent the accumulation of condensation water.
Temperature recovery
Natural warming: After taking the e-cigarette out of the low-temperature environment, leave it at room temperature for at least 30 minutes until the internal temperature rises before using it again.
Avoid heating: Do not forcibly heat with devices such as hair dryers or microwave ovens, as this may cause the battery to overheat or damage the device.
Inspect the equipment
Visual inspection: Confirm that the cartridges and the main unit have no leakage, cracks or deformations.
Functional test: After installing the cartridges, take a small puff first and observe whether the amount of smoke and the taste are normal.
Cleaning and maintenance
Clean the condensate: Use a cotton swab or tissue paper to wipe the interface of the cigarette cartridge, the airway and the interior of the main unit to remove the condensate.
Replace the e-liquid cartridge: If you notice an abnormal taste of the e-liquid or a significant reduction in the amount of smoke, it is recommended to replace the cartridge with a new one.
Outdoor use in winter
Reduce exposure time: Try to minimize the exposure time of e-cigarettes in low-temperature environments and immediately return them to a warm container after use.
Select low-temperature resistant equipment: Some e-cigarette products are optimized for low-temperature environments (such as using low-temperature resistant batteries or sealed designs), and can be given priority consideration.
Long-distance transportation
Insulated packaging: Wrap the e-cigarette in an insulated box or foam box, and place a heat pack inside (direct contact with the device should be avoided).
Temperature monitoring: During transportation, it is advisable to choose constant-temperature carriages as much as possible to avoid prolonged exposure to low-temperature environments.
Avoid freezing: If the inside of an e-cigarette is frozen, do not force its use. Wait until it is completely thawed before checking the device.
Regular maintenance: Low-temperature environments may accelerate equipment aging. It is recommended to conduct a comprehensive cleaning and inspection every three months.
Follow the manufacturer's guide: Different brands of e-cigarettes have varying degrees of tolerance to low temperatures. Please refer to the storage and usage suggestions in the official manual.
The core principles for storing e-cigarettes in low-temperature environments are to avoid extreme low temperatures, maintain moderate battery power, and prevent the accumulation of condensation water. Through reasonable preservation measures and preparatory work before use, the service life of the equipment can be effectively prolonged, ensuring the user experience and safety.
