Overview

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.

How do I install my dash cam?

There are 4 different methods to installing your dash cam which vary in difficulty. Check out our install guide for details.

Where do I find the latest firmware?

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.

Works great 24 hour coverage and lots of time remaining on battery life.

works well but expensive with unknown reliability

I have three cars. One of them is rarely driven and parked in the streets in the ghetto area. I have gotten that car broken into three times over the past four years. Luckily, every time except one my BlackVue captured part of the event, and I was able to have my car / renter's insurance company reimburse me for my loss. Having said that, changing the battery packs had been a chore. I used to use those battery packs for cell phones and piggy-back eight of them to run the dashcam for about three and half days, and it was a pain connecting them and charging them. The B-124X / B-124E combo works well. I put them in a sturdy plastic bag behind the front passenger's seat. And I cover it up easily with a jacket hanging on the headrest of the front passenger seat. Now my BlackVue DR650S-2CH can last five days with seven B-124X's. It is a VERY expensive solution, that's why I am only giving it a three star. And there is no data how long these battery cells will last, comparing to the cell phone battery packs using Panasonic 18650 cells that Tesla Model S/X use that is proven to last a long time even under high heat.

Why are these not more popular? Easy setup and operation. and will work to protect the system battery nicely.

It's a nice dashcam but I don't like the fact that I couldn't zoom into my videos on the phone app but only on a computer,so I sent it back and get the blackvue dr900s 2channel which is very awesome. But I really like the customer service at blackboxmycar, they are very helpful and answer all your questions.

Good but not perfect. But darn, they just announced an improved model!

Easy installation. I installed this to replace a 360 view dashcam that had terrible image quality. I’m very technically experienced and the app/install was not intuitive, but it all worked. Many of the online reviews that said the app was totally unusable seem a bit harsh. Image isn’t quite as crisp as I had hoped, but reasonably good. Candidly, the biggest disappointment is that the day after installing the camera, I received the announcement from BlackVue that they’ve announced at CES improvements to this camera and an even better 4GLTE camera! I depended on the advice from BlackboxMyCar and would have waiting for the updated models.

A must have for your car

The picture quality is great even in night mode very clear. A good investment for your safety.

Price and Quality sweet spot

My first dashcam, I installed with the additional 3-wire ACC kit in my 2010 Colorado Crew Cab. My only gripe is that I wish the rear camera could also be connected through the GPS module so that I don't have to disconnect the cable when removing the camera from my truck to look at footage. I find it easier to pop off the camera from the GPS mount, then connect with the supplied mini-USB cable to my laptop. Otherwise, the image and audio quality is really great, and it has all the necessary functions.

Really good dashcam, but......

Have really no complains withe the cam itself but the rear cam I can't use as the is no place to stick it to as the back of my truck is all fabric. If your gonna buy a dashcam that has front and rear cameras make sure there somewhere to stick it to. It would be nice if there were a small suction mount for rear camera as well. All in all I would recommend buying this dash cam!

love it

had mine installed Monday 1/20/2020 and it is working great

Hi John, thanks for leaving a review!
The best!

So professional and so knowledgeable. There was no question I had that they didn't have an answer for. They helped make my decision easy for what is a relatively expensive purchase.

Hi Kevin, thanks for leaving a review. Glad to hear that our team was able to help you out with all your needs!
BlackVue Power Magic EZ

Excellent products, prices and customer services very helpful.

Hi John, thanks for leaving a review! Let us know if you have any questions in the future.
2nd day of usage records crash

I installed two A119V3s - front and rear on my vehicle. I never got the chance to review any recordings. On the morning of the second day using them, while stopped at a STOP sign, I was rear-ended by a pick-up truck. I was pleasantly surprised to see that both units performed flawlessly.

What are the odds,lol?

During installation, I had a few questions which were quickly answered by the BlackboxMyCar staff. A truly professional business! BTW, video quality was excellent !!!

Hi TV, thanks for leaving a review! Glad to hear that you're loving your VIOFO, but even happier to hear that you're okay. Let's hope you don't get in any more accidents, but do reach out at anytime if you have any other questions.
Great camera setup, with one flaw...

Great camera setup, with one flaw...
I purchased the Viofo A129 Pro Duo with the Cellink Neo battery and HK3 ACC Hardwire kit, including an extra CPL filter for the rear camera. The video quality of the cameras are quite good. I've had four others made by Rexing and the Vantrue X1 and X3. The feel of these cameras are substantial, feels well made compared to others I've had and the mounts really hold. The CPL filters also appear to be made from quality materials and the wiring harnesses are excellent.

One of the features that I really wanted to take advantage of was the Auto Event Detection, while in parking mode. This feature buffers several seconds of video in memory ahead of an event so that when something does happen, it commits what is in memory to the microSD card and you don't lose the initial impact of the event. Otherwise, when nothing is happening, the camera is always watching but it is not writing to the microSD card. A great feature, but it does not work if you use the included GPS mount...what? So you have to decide, do you want GPS data or do you want Auto Event Detection; you can't have both!

I have sent a request to the support team to see if they can submit this as a future feature enhancement through a firmware update. I hope they can make that work, but for now this is why I can't give this a five star review.

Hi MWood, thank you for the feedback. We will keep that in mind and will relay that over to the VIOFO team as well. They do continuously upgrade their dash cam firmware, so we wouldn't be surprised if this gets addressed in the near future. Do let us know if you have any other feedback. Thanks for leaving a review!

Very Satisfied

Installation and setup was easy.

Hi David, thanks for leaving a review!
Easiest way

Shipped fast and was a good deal.

Hi Colin, thank you for leaving a review! Glad to hear that you love your purchase.
First Dash Cam purchase

After searching the internet for dash cam retailers, I settled on BlackBoxMyCar and I am very happy I chose them. I'm very pleased with my Viofo A129 Duo. I was able to have several questions answered on-line and that was a key factor in selecting my dash cam and BlackBoxMyCar. They will be my go to vendor for my next dash cam.

Hi John, thanks for purchasing from BlackboxMyCar. We're glad to have you as a happy customer :) Let us know at any time if you have any questions in the future.

VIOFO A119 V3 QHD+ Dash Cam

Hi Laenard, thanks for leaving a review!
Great item

Getting installed Monday 1/20/2020

Hi John, thanks for leaving a review!
Very Satisfied

I purchased the suction cup mount to allow me to transfer my Viofo A119V3 between vehicles.

The A119 V3 fits very securely onto the suction cup mount. This mount is superior to those I have used with other devices e.g. GPS in that it offers adjustment in both tilting and rotating, both of which can be locked in position, and when coupled with the titling lens it is very easy to get the best position for the Dashcam.

I found it very easy to secure the mount to my windshield.

Recommended if you intend to move the Dashcam between vehicles or to rental cars.

Hi David, thanks for leaving a review! Glad to hear that the suction cup mount was exactly what you were looking for.
Right fit

I ordered a part for my new car , It all worked out thank you.

Hi Spencer, thanks for leaving a review. Glad to hear that it all worked out for you. Let us know if you have any questions!
Awesome Rideshare Setup!

First of all! Very nice and knowledgeable people at blackboxmycar! Second very nice setup with power magic pro wiring kit! Also very discrete design! Love the video quality! Especially at night with the Sony Starvis! Overall good setup! Can barely see the cams. Thanks again Blackboxmycar.com/BlackVue!!! 👍👍👍

Hi Eric, thanks for purchasing from BlackboxMyCar. Glad to hear that your dash cam worked out for you! Thanks for including pictures as well :) Looks great!
Very Good - not yet great. But getting there.

I purchased the BlackVue DR900S 2 channel with interior facing IR after an attempted theft of my 2019 F-150 Lariat. It was already a purchase I had been considering in order to add a layer of security during both active and passive vehicle usage and I didn't hesitate to go with BMC given the number of positive reviews.

After a fast and painless exchange via email, BMC matched a lower price point offer for the kit that I had found on the internet. BMC even included a slightly larger storage card. Shipping and receipt went smoothly.

If I can fault BMC it is in the install and "commissioning" of the dash cam. Though I had done a fair bit of research and certainly am not one to shy away from peeling off some trim or crimping some wires, there was no step-by-step guide to installation that would have given an illustrated and comprehensive explanation of the process; now, this information exists and I was able to access it, but it was still a bit of a patchwork construction and an installation that I thought might take one hour took 2 days.

All said, though, the system is now up and running, so far flawlessly, in my vehicle. There has been a lot of trial and error, but the dash cam community is helpful and all of the information is available. You just need to look for it.

I will post a video review of my installation shortly - including hardwired battery installation.

Hi Alexander, thank you for leaving a review! We're glad to hear that we were able to help you with your order. You brought up some great points, and we will definitely take your feedback to heart for the future. We hope that the dash cam works out for you. Please let us know if you have any questions in the future.

BlackboxMyCar Add-A-Fuse Kit

Hi Brian, thanks for leaving a review!
VIOFO A119 12V Auto Hardwire Kit

Quality hardwire kit with reasonable length to the A119 and to the 12V battery source. Voltage reducer is small enough to fit in small spaces with rounded corners for ease of fishing into place. Fuse holder streamlined but difficult to open at first, 2nd time ok.

Hi Chester, thanks for leaving a review! Glad to hear that you were able to figure it out and install your VIOFO. Let us know if you have any questions. Thanks!
