Will a Power Bank Explode in the Car During Summer?
2 Answers
There is a possibility of explosion or spontaneous combustion under high temperatures. This is because most power banks contain lithium batteries, which are highly prone to explosion when exposed to direct sunlight in a confined car environment where temperatures can exceed 80 degrees Celsius. Below is relevant information about power banks: Introduction to Power Banks: A power bank is a device that can directly charge mobile devices and has its own energy storage unit. The main types of power banks on the market today are multifunctional, most of which come with standard USB outputs. They can generally meet the charging needs of various common mobile devices such as smartphones, MP3 players, MP4 players, PDAs, PSPs, Bluetooth headsets, and digital cameras. Essentially, a power bank is a convenient and portable large-capacity power source. It is a portable device that integrates energy storage, voltage boosting, and charging management. Functions of Power Banks: A power bank can charge mobile devices directly via an AC power source through its built-in charging plug and also has its own energy storage unit. It is essentially a hybrid of a charger and a backup battery, simplifying the setup by eliminating the need for an additional charging plug compared to a traditional backup power source.
Keeping power banks in the car during summer does pose an explosion risk, and I know this very well because a friend of mine did exactly that last summer, nearly causing a car fire. High temperatures can destabilize the chemical components inside lithium batteries. When the car interior heats up to over 60°C—like an oven—the battery may swell, leak, or even smoke and explode. I never leave electronic devices like phones or cameras in the car when parked under the sun in summer. My advice: don’t cut corners—take the power bank out and store it in your bag or bring it home. If removal isn’t possible, place it in a shaded spot like under the floor mat to avoid direct sunlight. This isn’t overreacting; safety comes first, especially as temperatures rise before the rainy season. Staying vigilant prevents accidents. Also, power bank quality matters—cheap off-brand products are more prone to issues, so invest in reputable brands. Saving small money isn’t worth risking bigger losses.
