Summer heat: Impact on performance and safety


Hot weather: A challenge for vapers
Lithium-ion batteries in particular are sensitive to high outdoor temperatures, which can shorten their lifespan and affect their performance. Overheating is a serious issue, as it can cause batteries to drain faster and, in the worst case, go into thermal runaway. This can lead to fires or even explosions. To avoid these risks, never store vape devices in direct sunlight — especially not in parked cars, where temperatures can quickly reach dangerous levels.
Store your gear somewhere cool and shaded, and consider using insulated bags for an extra layer of protection. Regularly checking the condition of your batteries is just as important. Dents, swelling, heat build-up or discolouration are warning signs that need immediate attention. Take extra care when charging your devices; they should never be charged in a hot environment if you want to keep risks to a minimum.
How high temperatures can change e-liquid quality


Heat can change the properties of e-liquids.
High temperatures can make e-liquids thinner, which can lead to leaks and negatively affect your vaping experience. This change in consistency can reduce vaporisation efficiency and leave you with a less satisfying vape.
Chemical reactions such as oxidation, which speeds up at higher temperatures, can also affect the flavour and quality of your e-liquid.
To minimise these effects, it’s a good idea to use e-liquids with a higher vegetable glycerine (VG) content in summer, as they are less prone to thinning in the heat. Cool, dark storage helps preserve the quality of your liquid. If you’re planning to spend time outdoors, carry your liquids in a cooler bag and avoid filling your tanks completely, so there’s room for thermal expansion.
High temperatures: How to vape safely and enjoyably


Safety precautions in direct sunlight
To keep your vape experience at its best in high temperatures, a few small device adjustments may be needed. Lowering the wattage, for example, can help prevent your device from overheating and stop the liquid from burning.
Regular cleaning and maintenance of your kit also help prevent technical issues and keep the flavour clean and enjoyable.
When vaping in direct sunlight, take extra safety precautions to avoid damage to the casing and make sure no fire hazards arise. It’s just as important to always transport your batteries separately in dedicated battery cases to prevent short circuits and other accidents.
Vaping in the sun: Risks and precautions


Is direct sunlight dangerous?
Direct sunlight can seriously affect the electronic components of your e-cigarette and cause damage that stops it working properly. Batteries and e-liquids can undergo chemical changes due to UV rays, putting not only performance but also the safety of your device at risk.
To keep your vape experience safe, avoid using your device during the midday heat or leaving it in direct sunlight.
Protective measures, such as covering the device when it isn’t in use or storing it in a sheltered area, can help minimise exposure. Regularly inspect your kit for external damage and adjust how you handle your device during summer to keep vaping safely in the long run.
Common mistakes: Vaping in blazing sun


1) Charging or storing batteries in the car
A common mistake is charging or storing e-cigarette batteries in a parked car. Strong sunlight can heat up the car dramatically, which can cause the batteries to overheat. This overheating can significantly shorten battery life and may also trigger dangerous chemical reactions, including fires or explosions. To avoid this, always charge and store your devices in a cool, shaded place.
2) Direct sunlight on the device
Many vapers don’t realise how damaging direct sunlight can be for their devices. Direct sun can affect not only the batteries, but also the e-liquids. E-liquids can become thinner and start to leak. To avoid damage, keep your vape device in the shade or in a protective pouch.
3) Storing e-liquids incorrectly
E-liquids should always be stored in a cool, dark place to preserve their quality. One mistake people often make is keeping liquids in places exposed to direct sunlight. This can alter the flavourings and reduce overall quality. The ideal spot is a cupboard or drawer that is not exposed to the sun.
4) Using liquids that are too thin
In summer, many people keep using the same e-liquids they use in winter. At high temperatures, however, it can help to use e-liquids with a higher VG content, as they are less likely to leak. Check the composition of your liquid and adjust it if needed.
5) Poor battery care
Batteries are the heart of every e-cigarette. Many vapers carry on without regularly checking the condition of their batteries. Watch out for signs such as swelling or excessive heat build-up. Symptoms like these can point to an imminent danger and call for immediate action.
Expert tips: Vaping in the summer sun


Tip 1: Choose the right storage spot for your vape device
To prevent your vape device and e-liquids from being damaged by the blazing summer sun, always store them in a cool, dark place. For example, the interior of a car parked in the sun can quickly reach temperatures that negatively affect battery chemistry and e-liquid quality. Drawers or cupboards in air-conditioned rooms are ideal, or at least rooms protected from direct sunlight.
Tip 2: Use e-liquids with a higher VG content
In summer, it’s wise to use e-liquids with a higher vegetable glycerine (VG) content. VG is thicker than propylene glycol (PG) and is less likely to become too thin at high temperatures. This minimises the risk of leaks in your device and makes for a more enjoyable vaping experience, even when it’s hot outside.
Tip 3: Adjust your vape device’s wattage
At higher temperatures, your liquid can become thinner, which may make it burn faster. To avoid this, reduce the wattage of your vape device accordingly. This helps prevent overheating and keeps the liquid vaporising consistently.
Tip 4: Don’t charge in the sun
Charge your e-cigarette in a cool, dry environment — not in blazing sun or in a hot car. High temperatures can severely reduce your battery’s lifespan and, in the worst case, create safety risks.
Glossary: Key terms


This term describes a dangerous chemical reaction inside a lithium-ion battery triggered by extreme overheating. The temperature inside the battery rises uncontrollably, which can cause it to ignite on its own. This situation is particularly risky when vaping in blazing sun, as high ambient temperatures increase the likelihood of thermal runaway.
A short circuit occurs when the electrical contacts of a battery become connected due to faulty insulation or loose metal objects. This can happen especially at high outdoor temperatures, when components of the e-cigarette expand and affect its build. A short circuit can lead to overheating and, in the worst case, fires or explosions.
High temperatures can cause e-liquids to become thinner and leak from your e-cigarette tank. That can mean both a messy experience and wasted liquid. Simple habits, such as reducing the fill level, can help avoid this issue.
High temperatures can affect vapour production because thinner liquid may not vaporise as effectively. This can result in less vapour and a different vaping experience.
Wattage determines how much power is used to vaporise the liquid. At high temperatures, setting the wattage too high can cause the liquid to overheat and burn, negatively affecting the flavour and potentially releasing harmful substances. Adjusting the wattage is essential for vaping safely and enjoyably.
