Precautions for the first use of e-cigarettes

When using an e-cigarette for the first time, it is essential to strictly follow the device’s characteristics and safety regulations to avoid damage to the device or a poor user experience due to improper operation. The following are the core precautions and practical operation suggestions, covering key links such as equipment activation, e-liquid compatibility, and safety protection:

First, equipment activation and initialization

First charging

Avoid overcharging: Use the original charger and charge for the first time until the indicator light goes off or it shows full charge (usually 2-3 hours). Avoid charging overnight to prevent battery aging.

Risks of charging and using simultaneously: Do not suction during charging. Some devices may trigger protection mechanisms due to voltage fluctuations, and even cause the battery to overheat.

Pretreatment of atomization core

Moisture-proof dry burning: After injecting oil into the atomization core, let it stand for 5 to 10 minutes to ensure that the oil guiding cotton is completely saturated. If you are in a hurry to use it, you can gently shake the device to make the e-liquid penetrate quickly, but be careful not to shake it violently to avoid oil leakage.

First empty suction: After installing the atomizing core, do not press the power button and empty suction 3 to 5 times to help the e-liquid initially moisten the heating wire and reduce the initial burnt smell.

Parameter debugging

Power setting: Start from the lowest recommended power level of the equipment (for example, a 0.5Ω atomizing core is suggested to be adjusted from 20W), and increase by 2-3W in each level until the smoke is full and free of burnt smell.

Air intake volume adaptation: Adjust the air intake hole according to the type of e-liquid – for high VG e-liquid (large smoke), open the air intake larger; for high PG e-liquid (mouth suction), close the air intake smaller to enhance the throat-hitting sensation.

Second, the selection of e-liquid and the standards for oiling

Principle of e-liquid compatibility

VG/PG ratio:

Large smoke equipment: Select VG 70% or above e-liquid to ensure dense smoke.

For small smoke/mouth suction equipment: Select VG 50% or less e-liquid to avoid poor oil flow.

Nicotine concentration: Beginners are advised to start with 3-6mg/ml and gradually get used to the throats to avoid dizziness or choking caused by high concentrations.

Details of oil injection operation

Oil injection volume control:

Top oil injection atomizer: Fill up to 1/2 to 2/3 of the observation window to prevent overflow.

Bottom oil injection atomizer: After oil injection, let it stand for 1 minute before closing the oil injection hole to prevent oil leakage caused by pressure difference.

Avoid mixed oil: Before changing the e-liquid, empty the old oil and suck it until there is no residual smell. Mixing e-liquids of different flavors can easily lead to cross-contamination of flavors.

Third, safe use and health protection

Operational safety

Prevent scalding: Do not cover the air intake hole with your fingers when inhaling. Do not inhale more than 5 holes continuously to prevent the atomizer core from overheating.

Prevent oil leakage: When placing the equipment flat, make sure the pipe tip is facing upwards. For long-distance transportation, it is recommended to use a sealed storage box.

Health management

Inhalation rhythm: Each puff should be spaced at least 10 seconds apart to avoid palpitations or dizziness caused by excessive nicotine intake.

Environmentally sensitive groups: Pregnant women, asthma patients and minors are prohibited from using. Second-hand smoke may still contain harmful substances such as nicotine.

Emergency response

Oil leakage response: If the e-liquid seeps into the equipment, immediately turn off the power supply, use a paper towel to absorb the surface liquid, and let it dry for 24 hours before using it again.

Burnt smell treatment: If a burnt smell appears, stop using it immediately, replace the atomization core and clean the equipment. Continuing to use it may damage the mainboard.

Fourth, equipment maintenance and storage

Daily cleaning

Disinfection of cigarette butts: Wipe cigarette butts with alcohol cotton pads every week to prevent bacterial growth.

Condensate cleaning: After daily suction, gently wipe the inside of the cigarette nozzle with a paper towel to prevent condensate from flowing back and corroding the circuit.

Long-term storage

Battery control: When not in use for a long time, charge the device to about 50% and store it. Recharge it once a month to prevent the battery from being over-discharged.

Environmental requirements: Store in a cool and dry place (15-25℃), avoiding direct sunlight or high-temperature environments that may cause the e-liquid to deteriorate.

Fifth, Common Misunderstandings and Tips for Avoiding Pitfalls

Mistake 1: Ignoring the instruction manual

Risk: The operation logic of devices from different brands varies greatly (for example, some devices require pressing the power button five times to turn on). Blind operation may cause the device to lock up.

Suggestion: Read the manual carefully before use, with emphasis on marking key steps such as charging, oiling, and power adjustment.

Misconception 2: Over-reliance on high power

Consequence: Blindly increasing the power in pursuit of a large amount of smoke can easily lead to the atomization core burning and the decomposition of e-liquid, generating harmful substances.

Principle: The standard should be “moderate smoke and pure taste”, rather than merely pursuing visual effects.

Mistake Three: Ignoring the wear and tear of accessories

Hidden danger: Continuing to use deformed or aged atomizing cores and sealing rings may cause oil leakage, short circuit or even explosion.

Action: Regularly inspect the condition of the accessories. Replace them immediately if cracks, deformations or oil leaks are found.

Key summary: When using an e-cigarette for the first time, the priority should be “safety – adaptation – maintenance”. By operating in a standardized manner, the lifespan of the device can be extended, and through gradual debugging, the most suitable parameter combination for oneself can be found. In case of any abnormal situation (such as strange smell, leakage, or overheating of the equipment), stop using it immediately and contact after-sales service. Do not disassemble or repair it by yourself.
