Viofo 329 is the best,

i buy 2 more for my mom and dad

Good quality, fast shipping

Works perfectly!

Works great. I attached them to 3 of my cars with Black Box battery packs.

Super easy to install and works great. No worries about having to leave my car parked for hours at a time any longer with the camera in parking mode recording.
Highly recommended for anyone with a dashcam.

Works as expected. Batteries will not charge fully with the vehicle charging, so need to pull them out and charge them from an outlet.

workrd perfect for my 590

The wedge tool for lifting seals and inserting cable was the best part. The tester was useful and the others parts were just incase I needed more. But I would buy these parts again with any install

Much better than the old style battery. This one lasts much longer

Simple install for dash cam.

Great product so far does a great job easy to install and connect not the strongest but packs a strong punch great prices AMA does exactly what’s it intended for.

Power Inverter meets all my expectations. Charging battery from home is far more convenient than from my car's battery, which periodically is drained by the powercell battery.

Cables were the perfect ones I needed. Customer Service was awesome.

Like the ability to let the external battery run down instead of my car battery. An even greater addition if you can pair it with a cam that you can schedule specific parking mode recording times or a cam that uses low power while parked as you could achieve possibly several days up to a week running on the external battery alone in parking mode.

Great cam, the "brain" box is a bit big for what it is, making it harder to find a good spot for it, but it works great!
