Input Cables

Output Cables

Which power output cable do I need?

When you purchase a dash cam battery pack to power your dash cam for parking mode, you have one fundamental question to answer, and that’s how are you going to connect the battery pack to your dash cam. Not sure which one you need? Check our Choosing the Right Output Cable for Your Battery Pack guide.

With the popularity of Cloud dashcams such as from BlackVue and Thinkware, PowerCell 8 comes with a 5V USB 3.0 power outlet, this simplify the setup of mobile router in the vehicles. ​

Expansion Battery for More Power

PowerCell 8 works with the Cellink Neo Extended Battery Pack, giving you more the option to expand for more power whenever you need.

Power Duration Capabilities

A fully charged BlackboxMyCar PowerCell 8 battery pack can run a single 1-channel dash camera for up to 48 hours, while a dual-channel system can be run for about 35 hours with its integrated 96Wh. This measurement based on continuous runtime.

How Does It Work?

When vehicle's ignition is switched ON, PowerCell 8 battery pack charges and supplies power to the dashcam.

When vehicle's ignition is switched OFF, PowerCell 8 battery pack supplies power to the dashcam independently until power depletes.

1. Simple installation using 12V Power Cable

Just plug the battery into the cigarette lighter socket of your vehicle using the included 12V Power Cable.

Changing Passwords

If you are planning on changing the battery password, you will need to enter the default password '1234' when prompted for the old password.

Note: There is no password retrieval or reset function. Password reset is a function that can only be performed by technicians at the manufacturer. The Reset function within the Battery Manager App is for resetting the default battery settings (ie. the Dual Charger setting) only and will not reset the password back to the default "1234".

Because of this, we strongly recommend that you don't change the password unless you absolutely needed to, and if you do change it, make sure to keep a record of the new password. Once you have changed the password, you will be asked to re-enter it every time you access the Settings menu within the Battery Manager App.

Excellent product!

Very easy to install! Works amazing in my EV! USB port is a plus for charging extra devices without putting strain on my EV’s 12v battery system. Only downside was having to order a Micro 3 fuse tap but this is in no way a flaw with the product. Just keep in mind a 3rd party Micro 3 fuse tap may need to be purchased if you need to tap a micro 3 fuse.

I need more juice

This is the perfect solution to not drain your car battery. Before I got my PowerCell 8, my dash cam system (3 cameras) was hard wired into my fuse box. It worked fine if I wasn't planning on using my parking mode with the motion detection activated, but what's the point of that. If you want 100% protection of your vehicle when your not in it, you need the PowerCell 8. With a 3 camera system in parking mode with motion detection on I can get approximately 8 hours of run time. Depending on the amount of movement around the vehicle. However, my commute time to recharge the PowerCell 8 to 100% does not allow it. Although it only takes approximately 1 hour to fully recharge the PowerCell 8 through the cigarette lighter socket my commute time is to short. I could hardwire my PowerCell 8 into my fuse box and cut the recharge time down, but to make sure my dash cams can run continuously without any worries of the PowerCell 8 running out I would need more juice. So if your commute is short and you have a multi camera system I would suggest getting an extended battery pack to piggyback onto your PowerCell 8.

Fourth Time's a Charm

Just got my fourth car& fourth dashcam setup. My other three utilize the car battery for parking mode- all set to a low voltage limit. This time I decided to spring for a Powercell 8. Absolutely worth the investment. Not inexpensive, but neither are car batteries. It fit easily under my driver's seat, and provides 10+ hours of continuous run time without fear of my car needing a jump. I was also unaware the battery has built in Bluetooth to monitor voltage, charge and runtime. Well worth the price and effort to install imo
