Does a Dash Cam Need to Be Charged?
2 Answers
A dash cam does not need to be charged. Here is a detailed introduction about dash cams: Some dash cams come with built-in batteries, which allow them to continue operating for a short period after the car is turned off. Once the battery is depleted, the dash cam stops working. After installation, a dash cam can record video images and audio of the entire driving process, providing evidence in case of traffic accidents. Precautions for using a dash cam are as follows: 1. Startup: Dash cams usually have a startup prompt sound. Pay attention to whether the dash cam turns on simultaneously every time you start the car. During daily driving, ensure the dash cam is in normal recording mode when it is safe to do so. 2. Usage: Develop the habit of formatting the dash cam's memory card once a month to avoid the situation where the storage card is full due to automatically locked videos, leaving no space for new recordings.
Dash cams usually don't require separate charging. They're typically powered through the vehicle's cigarette lighter or fuse box, automatically charging and operating when the car starts. Some models have built-in small lithium batteries mainly for emergency backup, like providing temporary power for parking surveillance. However, high summer temperatures may cause lithium batteries to swell, so newer models now use safer supercapacitors instead. If the car isn't driven for extended periods, the dash cam's power drain may cause time resets, but normal driving will restore power. For daily use, it's recommended to turn off parking surveillance - this protects the battery while avoiding frequent charging hassles, making usage both convenient and worry-free.
