Will a Power Bank Explode If Left in the Car During Summer?
1 Answers
Leaving a power bank in the car during summer poses a risk of explosion. When parked in an open space for an extended period under direct sunlight, the temperature inside the car can rise sharply, making it unsafe if there are flammable or explosive items inside. During summer, the following items should never be left in the car: 1. Lighters: Ordinary lighters primarily contain liquid butane, which is highly flammable and explosive. High concentrations of butane can explode at just 20°C under normal conditions. If the ambient temperature exceeds 55°C, the lighter's volume will expand. When outdoor temperatures are above 30°C, the interior of a sun-exposed car can reach 60-70°C. 2. Perfume: Perfume bottles are often tightly sealed, making them prone to expansion under high temperatures, creating a hazard. Additionally, the glass bottle can focus sunlight entering the car into a single point, potentially causing a fire. 3. Transparent glass bottles: Any transparent object like glass can reflect sunlight, and if it focuses the light onto a single point, it can generate high temperatures and combustion. 4. Sealed canned liquids or beverages: Carbonated drinks already contain gas, and slight shaking can cause the bottle to expand. Combined with thermal expansion, they are more likely to burst. 5. Power banks: As stated in their instructions, power banks should not be used in high temperatures, as this can be dangerous. 6. Electronic devices: Devices like smartphones contain delicate circuit boards that can be easily damaged by prolonged exposure to high temperatures inside a car. Batteries are even more hazardous, as they may swell or even explode in high temperatures. Therefore, electronic devices should never be placed on the top of the dashboard under direct sunlight or on the storage shelf between the rear seats and windows. 7. Reading glasses: Reading glasses act as convex lenses, focusing light. If exposed to direct sunlight for an extended period, the focal point can rapidly increase in temperature. If placed on a flammable anti-slip mat, this can lead to situations where the mat or car nearly catches fire.
