Is It Safe to Keep a Power Bank in the Car?
1 Answers
Keeping a power bank in the car is not safe, and it is not recommended to leave a power bank unattended in a car for an extended period. Power banks use lithium batteries, whose chemical properties are not absolutely stable. Whether due to thermal expansion and contraction, self-leakage of battery cells, or impacts and drops, there is a chance for issues to arise at any time. If it must be left in an unattended location, it is advisable to remove any flammable materials nearby or use a specialized explosion-proof and flame-retardant bag designed for lithium batteries. Mobile phones also contain lithium battery cells, and poor-quality or poorly designed waterproof phones carry certain risks. A power bank is a portable charger that integrates power supply and charging functions. It typically uses lithium battery cells as energy storage units, offering convenience and quick charging for digital devices such as smartphones and tablets anytime, anywhere.
