People often leave their smartphones, power banks, Bluetooth earphones, or other gadgets inside when parking their cars. Many consider this a normal habit, but doing so can prove extremely dangerous. When a car is parked in the sun for long periods, its internal temperature can reach 60 to 70 degrees Celsius. This temperature damages the devices. Let's explore why leaving battery-powered electronic devices inside can be dangerous.

High temperatures can cause battery explosions.
When a car is parked, its AC is off. However, due to sunlight, the internal temperature can reach 60 to 70 degrees Celsius. This high temperature is very dangerous for the devices inside. Most electronic devices, such as smartphones and power banks, are designed to withstand temperatures of only 45 to 50 degrees Celsius. Temperatures above this level can trigger thermal runaway in the batteries of these devices, meaning the battery can overheat and explode. In many cases, this explosion can even ignite the car seat, dashboard, or other items inside.

Not only heat, but extreme cold is also harmful to electronic devices. Extremely cold temperatures slow down the battery's chemical reactions, reducing charging capacity and potentially causing permanent damage. Therefore, leaving devices inside the car in the cold is not advisable.

Take these precautions:
Remove all electronic gadgets before parking the car for a long time.

If devices must be kept in the car, keep them in a heat-resistant bag or case.
Never leave gadgets on the dashboard or a sunny seat.
Open the windows slightly to cool the cabin.
