Power Magic Battery Pack B-112

The BlackVue Power Magic Battery Pack B-112 is a dedicated battery module that enables continuous parking-mode recording for compatible dash cams. It draws charge from the vehicle’s accessory socket while driving and then supplies stable power after the engine is off. The unit accepts 12 V or 24 V input, making it suitable for both passenger cars and light commercial vehicles.

Drivers who need reliable overnight surveillance

This pack suits owners who want their dash cam to monitor the vehicle while parked without draining the starter battery. It is not intended for users who require hard-wired permanent installation or those who need to power multiple high-draw accessories simultaneously. Buyers seeking an integrated camera-and-battery solution should look at a different product category.

One-hour recharge delivers up to twelve hours

A full charge completes in roughly one hour of driving, after which the 3000 mAh cell at 12.8 V can sustain a single-channel BlackVue for up to twelve hours. The output provides a steady 12 V at 1 A plus two USB ports for auxiliary devices. Performance remains consistent across repeated daily cycles because the pack recharges automatically each trip.
