Can Power Banks Be Left in the Car in Summer?
3 Answers
Power banks should not be left in the car during summer. Here are some key points regarding power bank explosions: 1. Causes: (1) Inferior or refurbished battery cells are highly prone to explosions. (2) Poor-quality circuit boards often fail to regulate properly. (3) Exposure to high-temperature environments. 2. Warning Signs: If a power bank shows signs of bulging, liquid leakage, or emits unusual odors, be cautious. While slight warmth during charging is normal, if it becomes too hot to touch, it is strongly recommended to stop charging immediately, place the power bank in a safe location, and carefully observe it before deciding whether to continue use.
During summer driving, I often worry about the safety of leaving items in the car. Power banks are made of lithium batteries, and with car temperatures soaring above 60°C in summer, they can easily overheat. Lithium batteries may swell under high temperatures and even catch fire or explode. I've read news reports where people suffered significant losses due to power banks catching fire in cars. Personally, I recommend not leaving power banks in the car, especially when parked in the sun. If you must carry one when going out, it's best to keep it in your bag or find a shady spot to store it. Regularly check your power bank for any signs of bulging, and replace old ones promptly. After adopting this habit, I feel much more at ease and recommend it to friends to stay cautious together.
Having driven for many years, parking in summer is a big problem - the car interior turns into an oven. Leaving power banks inside is extremely dangerous as lithium batteries can become uncontrollable when overheated. Once, a colleague left a power bank in the car all afternoon and found it too hot to touch when retrieved. Since then, I've been extra cautious - even parking under sunshades isn't enough as temperatures remain too high. For safety, I've developed the habit of taking power banks home after use, keeping only non-flammable items in the car. High temperatures can also shorten power bank lifespan. Short-term storage might be acceptable, but never leave them overnight or exposed for extended periods. Safety first - paying attention to these details can prevent major troubles.
