Experience reliable security and versatile power with the BlackboxMyCar PowerCell 5. This compact dash cam battery pack delivers up to 30 hours of parking mode protection while doubling as a portable power bank with its high-speed USB-C port.
Engineered with safe LiFePO4 technology, it prevents drain on your vehicle's battery, making it the perfect solution for daily commuters using premium dash cams.
The BlackboxMyCar PowerCell 5 is the ideal solution for drivers who need consistent power for their surveillance systems. With a 51.2 Wh capacity, this battery pack provides up to 16 hours of continuous energy for a standard 2-channel dashcam, or over 30 hours for a single-channel unit. It ensures your vehicle remains protected during work shifts or overnight parking without relying on car batteries.
By utilizing this external battery pack, you eliminate the wear and tear on your vehicle's electrical system. This setup ensures that your dash cam maintains full parking mode functionality, capturing every incident without the risk of a dead car battery in the morning.
Designed for the daily commuter, the PowerCell 5 is built to fully charge incredibly fast. When you use the included cable to connect via the cigarette lighter socket (12V–15V), the unit charges in about 65 minutes. For even faster results, you can hardwire the unit to your fuse box, achieving a full charge in as little as 33 minutes.
This efficiency means you don't need to drive for hours to generate enough power. Whether you are running a simple commute or a long road trip, the system manages input intelligently, prioritizing your dashcam while the battery pack recharges rapidly in the background.
The PowerCell 5 is more than just a dedicated dash cam battery pack; it serves as a versatile hub. It features two USB-A ports and a powerful USB-C port. This allows you to output 5V or higher to fast-charge smartphones, tablets, or even laptops directly from the battery pack while you are in the vehicle.
This flexibility makes it an excellent companion for mobile professionals. Unlike a standard hardwire kit that only serves the camera, the PowerCell 5 adds utility to your vehicle's interior. You can keep your dash cams running while simultaneously charging your mobile devices, all from one compact source.
Safety is paramount when installing electronics in your vehicle. The PowerCell 5 utilizes premium LiFePO4 (Lithium Iron Phosphate) cells. This chemistry is renowned for its thermal stability, capable of withstanding extreme temperatures without the risk of fire or explosion associated with standard lithium-ion batteries found in phones or generic power banks.
In addition to safety, LiFePO4 batteries offer superior longevity. They can endure thousands of charge cycles, ensuring that your battery pack remains a reliable part of your vehicle's security setup for years to come. This durability is essential for maintaining constant voltage delivery to high-end 4K cameras.
Space is often at a premium in modern vehicles. The PowerCell 5 features a slim design that makes it easy to hide under a seat or in a glove compartment. Its small footprint allows for a clean installation, whether you are using the cigarette lighter adapter or a hidden hardwire connection.
Despite its size, it is built with a durable metal casing for protection. It works seamlessly with major brands like VIOFO, Thinkware, and BlackVue dash cams. For installation help, visit our Dash Cam Installation Hub.

Compatibility Note: The BlackboxMyCar PowerCell 5 is designed strictly for 12V–15V vehicle systems. It is not compatible with 24V power systems commonly found in heavy-duty trucks, semi-trailers, or commercial machinery. Connecting this unit to a 24V system may cause permanent damage to the battery pack and void your warranty.
What is the difference between the PowerCell 5 and PowerCell 8?
The PowerCell 8 has a larger capacity and includes Bluetooth for app connectivity. The PowerCell 5 is more compact and includes a unique USB-C port for charging devices, but it does not have Bluetooth or an app. It is a streamlined battery pack focused on efficiency.
Will this battery pack work with my dash cam?
Yes, the PowerCell 5 is universally compatible. It works with any dashcam brand, including BlackVue, Thinkware, and VIOFO. It replaces your vehicle's battery as the power source for parking mode, ensuring your camera runs safely.
How do I install this into my car?
You have two options. You can use the cigarette lighter cable for a simple plug-and-play setup. For a cleaner look and faster charging, we recommend using the input cable to hardwire it to your fuse box. You can find guides on our website.
Does this provide enough power for a 4K dashcam?
Absolutely. The PowerCell 5 provides stable 12V output, which is perfect for high-resolution 4K dash cams. It can power a dual-channel 4K system for approximately 16 hours in parking mode.
Can I chain multiple batteries together?
No, the PowerCell 5 is a standalone unit and does not support an extension battery pack. If you need longer duration than 30 hours, consider the larger PowerCell 8.
How do I check the battery status without an app?
The PowerCell 5 features built-in LED indicators on the unit itself. These lights display the current charging status and remaining power, allowing you to monitor the voltage levels and charge state at a glance.
Is it safe to leave this in my car during summer?
Yes. LiFePO4 technology is designed to withstand high heat much better than standard lithium batteries. This battery pack is built to operate safely in temperatures up to 140ºF, making it ideal for hot climates.
Can I install the PowerCell 5 in a truck or commercial vehicle with a 24V system?
No, the PowerCell 5 is not compatible with 24V systems. It is engineered to operate within an input voltage range of 11.5V to 15V. For vehicles with 24V electrical systems (such as some semi-trucks or buses), you would require a voltage converter to step the power down to 12V before connecting it to the battery pack. Using the device directly with a 24V source will result in hardware failure.
