A dash cam can be connected to a power bank. A dash cam is a device that records images and sound-related information during vehicle travel, capturing the entire process of driving in video and audio. It consists of a microprocessor, data storage, real-time clock, display, lens module, operation keys, printer, data communication interface, speed sensor, and data analysis software. The functions of a dash cam include: 1. Protecting the driver's legal rights to avoid extortion or blackmail; 2. Enabling traffic police to handle accidents accurately and quickly; 3. Reducing driver violations and lowering the probability of traffic accidents; 4. Assisting courts in making accurate judgments when handling traffic accident cases.

As someone who loves tinkering with cars, I think it's perfectly fine to power a dash cam with a power bank. Most models come with a USB port, so you can simply plug in a 5V output cable. Just make sure the power bank's output matches the required wattage—it's best to choose one that supports 2A or higher to avoid insufficient power supply causing recording interruptions. In terms of capacity, I recommend a high-power model with 10,000mAh or more, which can last several hours for parking surveillance. I've tested it myself—it works great for outdoor camping or parking recording, but be cautious of high temperatures inside the car during summer, as the battery can easily swell. Always opt for reputable brands to ensure safety and avoid cheap, no-name products. Overall, it's a practical temporary solution for power issues, but don't rely on it long-term—car power sources are more stable and reliable.

As a seasoned driver with over 20 years of experience, I'd like to share some insights: I've used portable chargers a few times, especially during long trips when I didn't want to drain the car battery. They're super convenient – just carry them around and plug in for power, very mobile. But make sure to choose high-capacity products. I've tried 20000mAh ones that can last a whole day, giving peace of mind when parking and recording without worrying about battery drain. The downside is you have to recharge the power bank itself each time, which can be a hassle. I'd recommend prioritizing car outlets when possible. If you must use a power bank, ensure proper temperature control and avoid placing it in direct sunlight.

From my personal perspective, I do not recommend frequently using power banks, especially due to quality issues that may pose fire risks. There have been cases where inferior batteries exploded due to overload. The power consumption of a dash cam is around 5W, and a power bank may overheat, causing potential hazards. Official power sources are safer—don't take risks just for convenience. It might be acceptable for occasional emergencies, but always monitor the battery level and ensure the usage environment is well-ventilated.
