Bloc Power – Battery Pack B2 – BlackVue Battery Pack – 8000mAh

BLOC POWER is a dedicated power solution designed to extend your dash cam’s parking mode recording—without draining your vehicle’s battery. Instead of relying on your car overnight, BLOC POWER delivers clean, stable power to your dash cam, protecting your vehicle’s battery and ensuring reliable performance.

Features

  • High-capacity LiFePO₄ battery technology – 12000 AH 153 WH
  • 1CH – 50 Hours run time – 2 CH – 32 Hours Run Time Approx
  • Fast charging while driving
  • Extended dash cam parking mode recording
  • LCD status display
  • Adjustable power timer
  • 2 × USB-A fast-charging ports (up to 20W)
  • 1 × USB-C PD fast-charging port (up to 45W)
  • Built-in LED torch & emergency light

When your vehicle is running, the ACC (accessory) power source charges the BLOC POWER battery and your dash cam. When the ignition is switched off, ACC power stops and BLOC POWER automatically takes over—maintaining continuous power to your dash cam.

  • An intelligent built-in voltage detection system monitors
  • engine status in real time, enabling seamless switching
  • between driving and parking modes without user input.
  • In conventional installations, where the dash cam draws
  • directly from the vehicle’s main battery, recording time is
  • typically limited to 1–3 hours – often less depending on
  • battery condition. This is rarely sufficient for overnight protection.

HOW A BLOC POWER BATTERY WORKS

With BLOC POWER integrated into your system, parking mode recording time is significantly extended (see Runtime Guide on page 4), while eliminating drain on your vehicle’s battery. This supports reliable engine starts and helps preserve long-term battery health.

BLOC POWER also reduces the risk of interference with sensitive onboard electronics, including the ECU, thanks to its isolated power architecture. Installation is simpler than traditional hardwiring, with enhanced control and power management throughout

BLOC POWER BATTERY RUNTIME

Your BLOC POWER battery can power your dash cam in Parking Mode for up to 35 hours (B2) or 50 hours (B3). Actual run times will vary depending on the dash cam model, number of channels, and user settings.

The table below provides an approximate guide for typical single and dual channel dash cam systems.

EXPANSION

BLOC POWER features expandable power capability for extended performance. By connecting a second battery pack, total capacity and Parking Mode recording time can be increased.

A maximum of two batteries can be linked. B2 model can be combined within the same setup.

To connect two batteries, the optional BLOC POWER Expansion Cable is required.

Samuel ★★★★★

Took it on a two-day trip and left the dash cam running overnight for about 14 hours; the LED indicator still showed half a charge left. The 12000mAh capacity really does give you that extended parking mode security without worrying about your car battery.

Amelia V. ★★★★★

Finally a battery pack that actually keeps my dash cam running through a full weekend away from the car. The 12000mAh capacity gives me nearly 50 hours of parking mode, which is more than enough for my overnight shifts. Setup was straightforward and the peace of mind is worth every penny.

Sophia ★★★★★

Finally, a dash cam battery that actually lives up to the 50-hour parking mode claim—I've tested it overnight twice now and it held steady. The installation was straightforward, and it's nice not worrying about my car battery dying while the cam records.
