The Real Blind Spot is Time.

Eliminate the last weak point in security of your car.

In-car dash cam is normally connected to the existing car battery. This means that the car battery may be discharged if the dash cam is continuously powered during long-term parking. In winter, the battery drains even more quickly. You will need to prepare for this discharge.

On the other hand, there are ever growing number of people who use the constant power recording of dash cams to prevent the risk of parking terrorism. Features such as low discharge, and power saving mode cannot completely free your car from complete battery discharge. On top of that, there are now dash cams with 4g/5g connectivity features and AI monitoring systems, each contributing to additional power draw.

A fundamental solution to properly use dash cams is to pair with
Doubledog dedicated battery system.
Designed and engineered in South Korea,
Doubledog protects your car from time itself.

No car battery drainage. The most powerful and longest lasting.
The most advanced cells.
