## Description

In addition, the voltage cutoff function only works when the engine is stopped and automatically stops if the engine is started.

## Questions & Answers

**Q: Will this work with halo cam?**
A: As long as your halo cam works has a 12v supply line it will work. Unit comes with 12v cigarette lighter socket, but for mine I wired direct. I actually use this as a trigger to a 100amp relay and have that circuit run many items.

**Q: Compare power magic pro and ez, which one is better**
A: EZ is easier to install which would make it better in my opinion. The downside is that not every vehicle is compatible. PMP will work on any vehicle.

**Q: Is the power in line fused?**
A: Yes

**Q: Will this work with vava dash cam?**
A: its for Blackvuew dashcam as far as i know.

## Customer Reviews

### ⭐⭐⭐⭐⭐ A must if you own a dashcam
*by B***C on December 23, 2019*

Update: 08/06/2020Still using the PMP and no issues. Cuts current exactly at the set point. I think the dashcam would not be that useful without it. Already caught 3 incidents during parking. Worth every penny!Original Review:Recently I installed the 2ch Blackvue dr900s and used the PMP hardwire option. This is an amazing option if you want to track your footage during parking hours. The installation guide is straight forward. I used 2 quick taps and connected as guided. Never ha a problem of battery draining causing the engine not to start. Since my car battery is brand new I do not expect any problems in the near future. One recommendation is to check the voltage options of the unit you gonna but. The older versions have 11.6 and 12v settings which might cause a problematic start, especially in the colder weather if 11.6v is set. The newer version has 12 and 12.5v settings and you will be a little more on the safe side. I have my time setting infinity and voltage setting at 12v. Tested several times and shuts off when getting 12v left in the battery and that is more than enough to start the car without any issues. I have been using this module for a while during summer and now in the cold climate in Boston. In addition to these settings I also got a free hotspot (T Mobil e gave it for trial) and got a Verizo n 2GB/$10 plan. Now I receive text alerts live if something happens to the car.I am completely satisfied with this unit and highly recommend it.

### ⭐⭐⭐⭐⭐ Works great
*by A***R on October 19, 2020*

Works great. An added word of caution to make sure you buy the correct wire taps that your vehicle needs. The fuse taps that Amazon happened to suggest we’re not the right fuse size for my vehicle. My fault. Just make sure you’re getting regular vs mini vs low profile as your vehicle requires.

### ⭐⭐⭐⭐⭐ It does the job
*by V***L on August 22, 2022*

It works as described. Turns off the camera when the voltage hits the set level. Its a little tricky to get it to come on at first but works well after that.
