Batteries should not be exposed to sunlight under any circumstances, especially nickel-metal hydride and lithium batteries, as they are sealed and packaged. High temperatures will cause internal pressure to increase, which may lead to an explosion, even if it does not. explode, the internal electrodes will be deformed and the battery will be damaged. Other unsealed batteries will also cause the internal electrolyte to evaporate when exposed to sunlight, causing battery damage and failure. Therefore, the batteries have a reasonable usage temperature range and exposure to sunlight is not good.
It could explode.
General power banks are lithium batteries, which can reach temperatures above 80 degrees when exposed to sunlight in a closed environment in a car. However, the bAtteries are prone to explode at high temperatures, resulting in economic losses. The description of the power bank also mentions that it cannot be used at high temperatures otherwise it would be dangerous. If you want to use a power bank in summer, it is best to remove the power bank and other battery cells from the car when you get out of the car.
When using a car in summer, it is recommended not to place lighters, bottled water, carbonated drinks, power bank and other electronic products, toilet water, plastic accessories and toys in the car. prepare for proactive prevention. For example, apply a sunscreen film to prevent direct sunlight from entering the car. Check if there are any flammable objects left in the car, especially under the seats, in the spaces betweenthe armrest boxes and in the storage spaces. grooves of interior door panels, etc., and eliminate potential safety hazards one by one.
