Ever thought your video material from your dashcam is not there just because your dashcam ran out of power?

Luckily, there are batteries that can make your dashcams work on an external power source!

A separate power source from your car’s battery can be provided by an external dash cam battery pack. 

The parking mode features on a car camera are the key reason why anyone would want to use a power bank.

Parking mode is intended for use when your car is stopped and switched off, since you won’t have access to a direct power source as you would if it were running.

We’ve checked, rated, and ranked all of the best Dash Cam Batteries, you’ll find the best choice in the following guide.

What are the Best Dash Cams Batteries on the Market?

We prepared a list of the best dash cam batteries on today’s market.

Each one thoroughly described, we included their pros and cons and what to expect when you get a new dashcam battery.

Cellink NEO Battery Pack

VIOFO, Garmin, Rexing, APEMAN, Anker ROAV, KDLINKS, AUKEY, Vantrue, Street Guardian, and other dashcam brands use this battery bank.

The NEO can power your dash cam for up to 48 hours and takes about 45 minutes to fully charge.

If 48 hours isn’t enough, you can buy additional expansion battery packs that connect to the main NEO battery pack to significantly extend your dash cam’s parking mode time.

You can plug the power bank into your car’s cigarette adapter plug, which on most cars turns off when you turn your car off, and this will automatically charge the battery pack when your car is running. 

Alternatively, you can hardwire the Cellink NEO battery bank into your vehicle using the included hardwire kit.

This is actually quite simple, as all you’re doing is plugging a couple of wires into your fuse box and connecting a grounding wire to a metal screw.

Both installation methods will enable the battery pack to be self-sufficient and automatically recharge itself while your vehicle is running.


  • Long battery life.
  • Integrated smartphone app.
  • Excellent customer service and frequent updates
  • It provides a 32GB microSD card.


  • Expensive.
  • To use the LTE auto-upload, you must have an active data connection.

Blackvue B-124X Power Magic Ultra Battery Pack

BlackVue dashcams such as the DR900S, DR750S, and DR590 have the best battery pack setup.

The B-124X is compatible with virtually any dash camera that has a cigarette adapter plugin, or you can use a cigarette to USB adapter.

With the B-124X’s built-in Bluetooth, you can view the latest charging status and see how much dashcam life you have on your smartphone.

You’ll need to download the free BlackVue Battery app for your iOS or Android phone or tablet t use this feature. 

The app will show you how charged the battery is, how long it will take to fully charge it, how long the dashcam will actually operate, and even the battery temperature.

As with any battery bank, make sure it’s located in a place where it won’t be exposed to direct sunlight.

It’s also a safe idea to keep it secret from possible robbers’ eyes.

You can either plug the BlackVue battery pack into your car’s cigarette adapter socket to keep it charged, or you can hardwire it directly to your car’s fuse box.

When your car is running, both will charge the battery.


  • Simple or Hardwired installation.
  • Expanded capacity with optional Expansion Batteries.
  • USB Powered Output.


  • Weak durability.
  • Requires large capacity SD card.

BlackVue B-112 Power Magic Battery Pack

The best dash cam battery pack on a budget.

Not only can you power or charge your dashcam with its car cigarette adapter input, but you can also power or charge other electronics like your phone or GoPro.

This external dash cam battery does not need hardwiring into your vehicle.

Simply plug it into your car’s cigarette adapter, and it will automatically recharge the B-112 battery pack when your car is driving, ensuring that it is ready for when you park.

If you want to do it that way, you can use a hardwire kit to hardwire it into your car.

When you start your car, both of us have automatic charging.

It takes about an hour to fully charge this 3000mAH battery pack, and it gives your dashcam enough power to run for up to 12 hours.

Since each dashcam’s energy requirements differ, this estimate is based on the power consumption of the BlackVue DR650S-1CH dashcam.

The Lithium Iron Phosphate (LiFePo4) battery in the BlackVue Power Magic has LED lights that signify charging status.

The device is charging when the red LED is lit, and it is completely charged when the green LED is lit.

White LEDs illuminate the battery meter.

Overall, this is a decent budget battery bank from a reputable dash cam company that can run almost any dashcam in parking mode to provide 24/7 video protection for your vehicle.


  • 1-hour charge/12-hour operation
  • Decent price.
  • Good operating temperatures.


  • Low durability.
  • Poor quality.

Frequently Asked Questions

Can you replace your dashcam battery?

Almost all dash cams with an internal battery today are not built with the ability to detach or replace the battery.

Changing the battery on a dashcam isn’t the same as changing the battery on a mobile phone or digital camera.

Most experts believe that if your dash cam’s battery fails, you can buy a new one.

Is an external battery pack for your dashcam required?

For the most part, you’ll only need an external power bank for your car camera if you want to use the parking mode features on your dashcam.

When your car is parked in parking mode, the dash cam can sense motion or an impact and begin recording. 

Since you’ll be parked, your car will be turned off, and the camera’s power source will be turned off as well, it’s important to have a backup power source.

You can power the camera directly from your car’s battery, but if done incorrectly, this can fully drain the battery, as well as cause wear and tear on the battery.

Can I make my own dash cam battery pack?

Although it is possible to build your own external battery pack to power your dash camera, you will also need batteries.

Since the batteries are the most costly component of a DIY battery pack, you won’t save much money if any at all until you add in the time it takes to make and source the pieces.

Wrap Up

A dash cam’s battery isn’t designed to power the camera unit on its own; instead, it’s designed to receive continuous power from your car or a power bank.

The battery in a dash cam’s primary function is to provide only enough power to save the most recent video file when the vehicle is switched off.

This is why, increasingly, dash cams are omitting batteries in favor of a capacitor, which performs much better in high temperatures.
