BlackVue Power Magic Ultra Battery Expansion Pack (B-124E)

Note: The BlackVue Power Magic Ultra Battery Expansion Pack (B-124E) is meant to work as an extension to the B-124 Battery Pack. This will not work as a standalone product.

The Expansion Battery (B-124E) can store up to 6600mAh of power, so 10% more power than the Ultra Battery. Multiple Expansion Battery units can be connected in sequence to provide even larger capacity. With dash cams becoming more common, it’s much more apparent that we need a new way to power these cameras. If you leave your car parked for long durations and want even more protection from hit and runs, the BlackVue Power Magic Ultra Battery Expansion Pack (B-124E) is perfect for you.

Power Duration Capabilities

A fully charged BlackVue B-124 Power Magic Ultra Battery Pack can run a single 1-channel dash camera for about 45 hours, while a dual-channel system can be run for about 25 hours with its integrated 76.8Wh. This measurement based on continuous runtime.

A fully charged BlackVue B-124 Power Magic Ultra Battery Pack can run a BlackVue DR900S-1CH dash camera for about 25 hours while a dual channel system like the BlackVue DR900S-2CH will be about 15 hours with its integrated 76.8Wh. On the other hand, a BlackVue DR750S-1CH dash camera for about 28 hours while a dual channel system like the BlackVue DR750S-2CH will be about 18 hours.

Having one Expansion pack attached can double these numbers. The expansion packs differ from the base system by having a boosted, integrated 84.5 Wh capacity.

What is a dash cam?

A dash cam stands for a dashboard camera that is mounted inside the vehicle, usually on the front windshield. A dash cam, depending on the model, can do many things such as record both when the vehicle is being driven and when it’s parked, record audio, provide a connection to a smartphone app so that video can be reviewed and saved on the spot, etc.

What is an IR dash cam?

An IR dash cam is a dash cam with infrared lights that provide recording details under poorly-lit conditions, as well as total darkness. These are dual-channel dash cam setups with a regular front-facing unit and a secondary unit that comes with infrared lights.

The secondary unit is typically mounted to face and record the interior of the vehicle, and thus is especially recommended for rideshare users, such as for Uber and Lyft, or for commercial use, such as fleet managers.

Why buy a premium dash cam?

There are a few reasons as to why this is the case, and these reasons make a huge difference. Learn more about premium features including design, parking mode, smartphone integration, 4K UHD video resolution, g-force, ADAS, memory card storage and more.

What is parking mode?

Parking mode recording is a feature of a dash cam that keeps your dash cam recording footage even when the vehicle is off. Typically found only in premium dash cams, parking mode provides around-the-clock protection and surveillance for the vehicle.

What is Wi-Fi & GPS?

The wi-fi feature in a dash cam is what allows a smartphone to be paired to the dash cams. Unlike a regular wi-fi network signal that gives you internet access, the purpose here is just to connect the dash cam and smartphone together.

The GPS feature in a dash cam shows the vehicle’s speed and, for some models, the location of the vehicle with Google Maps integration.

What is a Radar Detector?

Radar Detector is a device that detects invisible radar waves that are used to get a speed measurement of your vehicle. When the radar detector is triggered by the invisible radar waves, an audio and visual alert is set off for the driver to slow down to avoid speeding tickets.

What are false alerts on a Radar Detector?

False alerts are when the radar detector picks up on radar signatures not from a police officer. Two common types are stationary and moving false alerts.

What are the differences between a Ka, K, and X bands?

X Band radar waves fall between 8.0ghz and 12ghz. Law enforcement X band radar guns operate universally on 10.5ghz.

K Band radar waves fall between 18ghz and 27ghz. Police K band radar operates strictly at 24.125ghz and 24.15ghz.

Ka Band radar waves fall between 33.4ghz and 36.0ghz. With very few exceptions, if your radar detector alerts a Ka band, you can be sure there is a legitimate threat ahead or behind you.

What is MRCD or MultaRadar CD?

MultaRadar is a brand new threat to drivers across North America. Unlike traditional technology, MultaRadar does not operate at just one frequency which renders many old radar detectors obsolete from detecting MultaRadar.

What is the return policy?

We fully stand behind our products and are absolutely confident that they will meet and exceed your highest expectations. However, within 30 days of purchase, if you are unhappy with your unit or if you simply wanted to try out a dash cam, we will refund your money. No questions asked. For more details, click here.

I recently purchased the BlackVue Power Magic Ultra Battery Expansion Pack (B-124E) and I connected it to my Powercell 8 Battery Pack and it works flawlessly. It was also great that the Blackview (B-124E) was on sale for $269.
