Can Power Banks Be Left in the Car?

[Isaac]

Power banks should not be left in the car for extended periods. Here are the reasons why power banks should not be stored in vehicles: Battery: Power banks typically use lithium-ion batteries, which have relatively unstable chemical properties. Whether due to thermal expansion and contraction, self-discharge of battery cells, or impacts and drops, there is always a chance of issues arising at any time—though the probability is low, it's not worth the risk. High interior temperatures: Under direct sunlight, temperatures inside a closed vehicle can exceed 80°C, making battery explosions more likely in high heat. Health hazards: Prolonged storage of lithium-ion batteries can negatively impact human health.
