Why External Battery Pack

When the dash cam operates in parking mode, it draws power from the vehicle's battery via a parking surveillance cable until the battery voltage dropsto the preset limit, at which point the cable shuts off. This means the duration of surveillance depends on the battery's condition. Aging batteries may only support a few hours of monitoring, and prolonged use can significantly reduce battery lifespan.

The external battery pack charges from the vehicle's alternator while driving, storing energy for parking mode. This ensures constant surveillance withoutdraining the vehicle batterythereby extending its lifespan by preventing excessive discharge.

Extended Parking Surveillance Duration

The dash cam battery pack powers the dash cam while driving, using the vehicle's engine. During parking, it provides uninterrupted surveillance without draining the vehicle's battery, offering extended monitoring for comprehensive security.

Ultimate Battery Care

The battery pack features automatic current limiting, delayed charging, and external protection. It adjusts charging to prevent vehicle battery drain, delays startup to avoid excessive load, and manages temperature, discharge, and other conditions to ensure safe, long-lasting operation.

Tailored Installation for Easy Plug-and-Play

STEP1. Charging Setup

Opt.1 Cigarette Lighter Charging
By connecting to the vehicle's cigarette lighter socket, power is routed to the battery pack, which then directly powers the dash cam, enabling hassle-free parking surveillance without draining the car battery.

*If the vehicle has a constantly powered cigarette lighter, this method is unsuitable.

Opt.2 Hardwire Connection
Utilizing hardwiring connected to the vehicle's fuse box for charging
provides a faster charging speed, up to 30%. For those prioritizing
charging speed, opting for the hardwire connection is recommended.

STEP2. Discharging Setup

Opt.1 Directly Connect to Dash Cams
The battery pack features a Type-C 5V output interface for direct connection to the dash cam with the included cable

*For 70mai dash cam users, the battery pack enables parking surveillance without a hardwire kit if the 4G module is unused.

Opt.2 Connect via Parking Surveillance Cable
It also includes a 12V output interface, compatible with all 70mai dash cam models equipped with 70mai standard Hardwire Kits or 4G Hardwire Kits, and most other dash cams with parking surveillance cables, ensuring seamless integration for various setups.

STEP3.Securely Mount Your Battery Pack

Considering the vibrations during driving, it's recommended to securely place the battery pack with its wide surface facing downwards on the vehicle's floor, using the provided adhesive Velcro for fixation. After securing the battery pack, use cable ties to fasten the wires to prevent any
loose connections.
