Can Power Banks Be Left in the Car During Summer?

Power banks should not be left in the car during summer. Most regions in China experience high temperatures in summer, and power banks can explode when exposed to extreme heat. Under direct sunlight or in a closed car where temperatures can exceed 80°C, power banks are highly prone to explosion. Additional information is as follows: 1. Avoid engine overheating: When driving in hot summer weather, always monitor the temperature gauge, which should generally not exceed 95°C. This is especially important when the vehicle is carrying heavy loads or driving on mountainous roads. If the temperature rises too high, promptly park in a shaded area to cool down and open the engine hood for ventilation. Once the temperature drops, check if the engine cooling system is low on coolant and identify the cause of the overheating. 2. Monitor tire temperature: During summer, avoid driving for extended periods. Take breaks every 2 hours or after a certain distance to inspect tire temperature. If tire pressure increases due to overheating, park the car in a shaded or tree-covered area to allow the tires to cool down naturally. Do not release air or splash cold water to reduce tire pressure and temperature. Additionally, avoid sudden braking during summer driving, and strictly refrain from overloading the vehicle.

Leaving a power bank in the car during summer? It's really unsafe! I've been driving for many years, and the car gets as hot as an oven in summer, easily reaching 60 degrees Celsius. Lithium batteries are extremely dangerous under high temperatures—they can swell, short-circuit, or even explode. A friend's car once caught fire because they forgot to take out their power bank. My advice is to always take your power bank with you when you park the car—don't leave it in the car for convenience. Carrying a small power bank in your bag is much safer, preventing accidents that could harm yourself or others. High temperatures also shorten its lifespan, rendering it useless after just a few uses—wasting money. Make it a habit to prioritize safety; keep only non-perishable small items in the car.

As a tech enthusiast, I've tested the temperature resistance of power banks. Lithium batteries are afraid of high temperatures; exceeding 55°C can accelerate aging or failure. In summer, parking lot temperatures can reach 70°C, and leaving a power bank in the car for a few hours may cause it to bulge, leak, or even spontaneously combust, posing significant risks. I recommend not leaving it in the car; carry it with you or use a dedicated small bag for storage. Reputable brands may be slightly safer, but the harsh car environment can easily reduce battery capacity by over 50%. When going out, keep it in your bag—cool and worry-free. High temperatures also affect charging speed, making it not worth the trouble. Pay more attention to battery health; don't risk big losses for small gains.

As a parent, my child often forgets to take the power bank, so I strictly enforce not leaving it in the car during summer. High temperatures make lithium batteries unstable, and in case of explosion or fire, harming oneself or others is simply not worth it. It's advisable to check items after each car use, bringing the power bank home or keeping it in a bag. The temperature inside a car can be alarmingly high, and even the trunk doesn't eliminate the risk. Teach children safety habits, keeping important electronic devices away from heat sources. Buying a heat-insulated bag might offer some buffer, but it's not recommended—carrying it with you is more reliable. Small details determine major safety; don't be lazy.
