Product details

Overview

Meet the BlackboxMyCar PowerCell 8, a high-capacity dash cam battery pack designed to keep your video system powered through longer drives and parked periods. With 96Wh of energy (7500mAh), it delivers robust reserve power while remaining compact enough to fit discreetly behind the dash.

Key advantages

  • 96Wh / 7500mAh capacity with about 25% more power than the previous model
  • Hardwired charging can reach a full charge in roughly 50 minutes, helping you get back on the road quickly
  • Battery status monitoring via a companion app, so you know remaining capacity and estimated recharge time
  • Flexible connectivity with 12V car socket, hardwiring cable, and other input cables for versatile installation
  • Integrated 5V USB 3.0 outlet to charge devices while you drive or park (not for powering the dashcam due to parking mode variation)

Compatibility and setup

The PowerCell 8 supports a wide range of dash cam brands, including BlackVue, Thinkware, VIOFO, FineVu, Nextbase, Nexar, Garmin, Vantrue, and more. Some dash cam models may require spliced wiring for full functionality. Because parking mode activation methods differ, using the included output cables is highly recommended for best results.
