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 drops to 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.
This external battery pack charges from the vehicle's alternator while driving, storing energy for parking mode. This ensures constant surveillance without draining the vehicle battery thereby 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.
Universal dash cam compatibility The XT30 output port simulates standard car battery signals (VCC/ACC/GND), while the included 3.3m Type-C ensure compatibility with most dash cam models on the market.
High capacity power bank This battery pack uses premium 26650 LiFePO4 cells with an exceptional 7500mAh/96Wh capacity, which can still maintain 70% capacity after more than 2,000 charging cycles, ensuring long-term reliability and safety compared to standard lithium-ion batteries.
Rapid 60-minute charging technology Through hardwired connection, this battery achieves a full charge in just 60 minutes with smart 20-second delayed charging to protect your vehicle's electrical system during ignition. (This battery pack charges via hardwired fuse box connection)
Seamless 24/7 parking surveillance When your engine turns off, this system automatically switches to its internal battery power, allowing continuous dash cam recording without draining your car's battery.
Step 1 - Charging setup: 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.
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)
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.
Step 3 - 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 hook & loop for fixation. After securing the battery pack, use cable ties to fasten the wires to prevent any loose connections.
Discharging output: XT30 11.2V-14.2V up to 2A; USB Type-C 5V up to 2.4A
Full charge time: Approximately 90 minutes (with car cigarette lighter); Approximately 60 minutes (with hardwire connection) Note: Actual usage may vary due to differences in individual products, usage conditions, and environmental factors.
