Best Dash Cam Battery in 2020

An external dash cam battery pack can independently power your dash cam and provide a separate power source from your cars battery. The main reason why someone would want to use a power bank is for the parking mode features on their car camera. Parking mode is meant to be used when your car is parked and turned off, so you won’t have a direct power source like when your car is running.

Below we have listed the best rechargeable battery packs for dash cams:

Cellink NEO Battery Pack

Cellink NEO Dash Cam Battery
Check Price on Amazon

Best all around battery bank for all brands of dash cams like VIOFO, Garmin, Rexing, APEMAN, Anker ROAV, KDLINKS, AUKEY, Vantrue, Street Guardian and more.

The NEO can provide up to 48 hours of power for your dash cam and takes about 45 minutes to fully charge. If 48 hours is not enough, you can purchase multiple expansion battery packs that connect to the main NEO battery pack to drastically increase your parking mode time on your dash cam.

You can either have the power bank plugged into your cars cigarette adapter plug, which on most cars turns off when you turn your car off, so this will automatically charge the battery pack when your car is running. Or, you can hard wire the Cellink NEO battery bank into your car with the included hard wire kit. This is actually pretty easy, as all you’re doing is plugging a couple wires into your fuse box and attaching a grounding wire to a metal screw. Both install options will allow the battery pack to be self sufficient and automatically recharge itself when your car is running.

Built-in Bluetooth allows you to view charging status, amount of record time and more directly on your smart phone.

Dash Cam Battery FAQ

Do you need an external battery pack for your dash cam?

For the most part, you will only need an external power bank for your cars camera if you plan on using your dash cams parking mode features. Parking mode usually means that the dash cam will detect motion or an impact when your car is parked and start recording. Since you are parked, your car will be off and the power source to the camera will be off as well, so it’s important to have another power source. You can run the camera directly off your cars battery, but this can sometimes cause a completely drain on your car battery if not used properly and it also causes wear and tear on the car battery by repeatedly running it down. That’s why it is better to have a dedicated external dash cam battery.

What dash cam has the longest battery life?

The battery inside a dash cam is not meant to actually power the camera unit to run on its own, a dash cam is meant to get constant power from your car or a power bank. The only purpose of the battery in a dash cam is to have just enough power to save the last video file when you turn your car off. This is why more and more dash cams don’t even have batteries and instead use a capacitor, which does far better in high heats. ******More info on the difference between a battery and a capacitor in a dash cam.

Can you replace your dash cam battery?

Nearly all dash cams today that have an internal battery are not made to have the ability to remove or replace the battery. Replacing a battery on a dash cam is not like it might be on a cell phone or digital camera. Most would recommend that at the point of battery failure, you will want to buy a new dash cam.

DIY dash cam battery pack

While it is possible to put together your own external battery pack that is meant to power your dash camera, you are still going to need batteries of some kind to make it. The batteries are the most expensive part of a DIY battery pack, so in the end you’re not actually saving much money if at all after you factor in the time spent to create and source parts.
