Quick answer

Use the 70mai Battery Pack when you want parking surveillance without draining your car battery, especially if you park for long periods or don't want a complex hardwire installation.

Why not just use a hardwire kit?

A hardwire kit powers your dash cam directly from the car's fuse box, but it still draws from the vehicle's battery. If you park for extended hours or days, that drain can leave you with a dead car battery. The 70mai Battery Pack stores its own energy and powers the dash cam independently during parking, preserving your car's starting power.

The trade-off is that a hardwire kit charges this battery faster, but even with a simple cigarette lighter plug, you get reliable parking coverage. If you only park for short periods and trust your car battery, a hardwire kit alone might be enough. But for frequent or long parking sessions, the battery pack removes the worry.

Frequently asked questions

Does the battery pack work with any dash cam?

Yes, it is compatible with most dash cams that have a parking surveillance cable, including many 70mai models and other brands. Check your dash cam's parking cable compatibility before purchase.

How long does the battery pack last on a full charge?

The exact duration depends on your dash cam's power draw and parking mode settings. In general, it provides several hours to a full day of parking surveillance, depending on usage. You can monitor the battery level through the dash cam app.

Do I need a hardwire kit to use the battery pack?

No, the battery pack works with a standard cigarette lighter power cable. However, using a hardwire kit (sold separately) charges the battery faster and is recommended if you drive short distances or want the fastest recharge between parking sessions. If you drive less than 30 minutes most days, consider the hardwire kit for faster charging.
