- Being able to record footage even when the car engine is turned off is the primary advantage of parking mode, and the length of recording time can be extended through dash cam battery packs. This is helpful for drivers who want to monitor their car when it's parked overnight (especially in unfamiliar locations) or for several days or weeks, for example, when you are travelling. Dash Cam battery packs will provide an average of 25 hours of parking mode (Depending on the dash cam) compared to 6-8 hours provided by an average car battery. Dash cam battery packs are particularly useful for capturing incidents, accidents, or vandalism that can occur while you’re away. - Beyond monitoring, dash cam battery packs also protect your vehicle battery, which prevents damage to your dash cam and vehicle battery, extending their overall lifespan. If a dash cam or any power source draws power from your vehicle battery when it is off, it will lead to additional wear and tear on the vehicle battery. But a dash cam battery pack avoids this issue completely, handling all power draw from the dash cam. - Moreover, dash cam battery packs are a great alternative if you don’t want to hardwire your dash cam to your vehicle’s fuse box but still want parking mode. As dash cam battery packs can connect to the vehicle’s cigarette socket directly, this also means there is less stress on the vehicle’s own battery as the battery pack stops drawing power when the car is off. - Battery packs are especially recommended for cars with small batteries. Smaller batteries, for example, in BMWs and hybrids, have less power capacity, which translates directly to even less parking-mode recording. It’s not uncommon for many Japanese Domestic Market (JDM) vehicles to only last 2-3 hours before the voltage cutoff kicks in. For BMWs, the issue is not with the size of their batteries but with their computer system, which is overly sensitive to battery discharge. Battery packs fully bypass this issue, and are always recommended for vehicles like these. Furthermore, for exotic or european vehicles which require much more specific and expensive batteries, a battery pack is ideal for protecting it , and ensuring it lasts in the long-term. - While Dash Cam Battery Packs aren’t the only battery type around, they are the best choice for dash cams. Unlike USB power banks, Dash Cam Battery Packs are made from LiFePO4, (Lithium Iron Phosphate), which emphasizes durability, temperature tolerance, large power storage, and being able to handle frequent charging or discharging cycles. Standard USB power banks struggle with how much power dash cams require, and how often they require it, staying ever vigilant as they watch over your vehicle.

Dash Cam Battery Packs are meant to be hidden somewhere safe, preferably under the driver's or front passenger's seats, or areas in the trunk or in the glove box compartment. For instance, the ENERGYWELL BATTERYPACK P6 includes velcro dual-sided adhesives, making them useful when mounting onto carpets. The installation process for dash cam battery packs can be categorized into two main methods: hardwiring, or the simpler method through a Cigarette Lighter Adapter(CLA).
