Battery Packs For Dash Cams 2022 / 2023

If you’re going to run your dashboard camera in parking mode, you will need a power supply when the car’s engine is off.

The simplest option is a hard-wiring kit that has some sort of low-voltage cutoff, so the car’s battery won’t accidentally get drained by your dash cam. A hard-wiring kit is a perfectly good, and inexpensive, solution.

For a more high-end setup, and to protect your engine’s battery further, you may wish to completely separate your dash cam’s power circuit from the car’s battery. This can be achieved by installing a battery pack.

At this time, there are only a handful of battery packs to choose from. The manufacturers are: BlackVue, Thinkware, and Cellink. This article gives you a complete overview of how they compare to each other.

All battery packs are compatible with each other, meaning you can run any brand of dash cam with any battery.

Battery packs that support Bluetooth come with an app that lets you monitor the battery’s charge.

NOTE: Take the “parking mode duration” advertised by manufacturers with a huge grain of salt. Battery duration varies greatly depending on the model of dash cam you have. If you know your camera’s power consumption in mA, you can calculate how long the battery will last (divide battery capacity by power consumption).

BlackVue B-112

BlackVue B-122 battery pack

Price: $150 — see Amazon US / CA / UK (affiliate links)

Capacity: 3000 mAh / 38.4 Wh

Size: 6.8 x 5.3 x 3.7 inches

The B-112 was the first dash cam battery pack, to be released by none other than BlackVue, who were once again ahead of the curve.

Nowadays, the B-112 looks rather clunky. Not only is it the largest battery pack available, but it also has the lowest capacity. Its low price is a plus though.

Extra Capacity: BlackVue B-124E

BlackVue B-124E battery expansion pack

Price: $270 — see Amazon US / CA / UK (affiliate links)

Extra capacity: 6600mAh / 84.5 Wh

The B-124E (shown below in the photograph) is an expansion pack. It won’t work on its own, but hook it up to any of the other battery packs presented here, and it will extend their capacity by 6600 mAh.

According to the manufacturer, that’s over 56 hours, but this obviously depends on your dash cam’s energy consumption. So it may be a lot less, especially if you’re running a high-end dual channel camera.

The B-124E will work on top of the BlackVue B-112 or B-124X, but it has been reported to also work with the PowerCell 8.

You can connect as many of these as you want in series, by using the connector on the right.
