Can a Dash Cam Be Connected to a Power Bank?

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.
