Sporting a slimmer design, the PowerCell 8 carries 25% more power than the Cellink NEO, giving you up to 35 hours of parking mode protection for a dual-channel system.

Higher Capacity for More Power

The BlackboxMyCar PowerCell 8 can be charged fully within 50 minutes of driving with the rapid and safe charging control circuit. ​

Faster Charging: despite a higher capacity, the PowerCell reaches a full charge at as little as 50 minutes.

Check Battery Status with App

PowerCell 8 comes with Bluetooth built-in and best of all, it shares the same Cellink NEO Plus Battery Manager App, available free from both the Apple Store or Google Play store.

The Battery Manager App allows you to manage the settings and check the battery performance with just a few taps of your finger even if the PowerCell 8 is installed out of sight.

Use the Battery Manager App to:

  • check remaining capacity or time to full charge
  • control settings like charging current, voltage cutoff, LED indicators

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.

2. Hardwire installation using Hardwiring Cable

For fastest charging speed, connect the battery to the fuse panel.

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.

Powercell 8 app

Need to be able to turn the switch (low, off, high) from the app then every would be perfect.

They deleted my last review, proves they would have more 1 star reviews

They ship these out this what they call a common problem and want you to incur added shipping and down time returning the Powercell 8 to get fixed for this known common problem(their words) But rest assured they will fully test the replacement. Horrible customer service and a shady company for deleting reviews. I would recommend to buy from a different company.
