9.8ft OBD Hardwire Kit, Hardwire Power Cable with LED Screen | 3 Gear Shifting, USB-C, Low Voltage Protection for Parking Mode, Compatible with All DashCams

This works exactly as intended. Plenty of excess cable. The low voltage shut off and digital readout is a nice plus. I drive a Nissan Leaf so being able to monitor the 12-volt battery voltage is very important. If you know you know. This works great with my Vantrue 360 cam. Should work with any dash cam that uses USBC for power. Only thing that would be nice would be an option to set the exact voltage cut off instead of having to rely on three preset levels and an old school switch design. I'm sure there's room in the display box to add the necessary hardware. Highly recommend if you are looking for a super clean install.

Great cable! The 10ft length is perfect and gives plenty of reach. The LED light is a nice feature and makes it easy to see when it's powered. Works exactly as expected and feels durable. Very happy with this purchase!

Makes installation easy

I currently have it equipped for my Vanture N4 pro camera. The cable is long enough to reach right behind the rearview mirror, still have enough dangling next to my foot. Comes with the sticky part to attach to the side, but I don't that in case some day I decided to switch dashcams which may need a different OBD reader entirely, especially if it's not USB C entry. It has 3 voltage options, for my vehicle or dashcam, not sure which one, tends not to work well with the highest setting on. I'd have to bring it to the middle setting in order for my dashcam to operate while it's parked.

Was a bit confused on how to install it at first but eventually I figured out how to put it in. There is plenty of extra space for the cable to run so make sure you start at the dash cam and then work your way down to where the cable plugs in. As far as I'm aware every single car has a plug-in spot for one of these edit: I originally put this at five stars. I'm now bringing this down to four. It says it has a display so you can see how much power is being pushed into it and it does. And if it drops below a certain voltage then the dash cam will turn off. Here's the thing with this that does work and it will turn off the dash cam. However, it does not turn off the display and it still draws power. So if you end up going through a period of like 5 or 6 days where you don't drive then it will kill your car battery. So if it's going to be a couple of days where you're not driving then unplug the hard wiring kit from the car itself. This may be difficult. Depending on what type of car you have. I would recommend figuring out how you would install this on your car. A lot of cars. The plug-in is right above the brake and gas pedal, but make sure that that is where yours is so that if you do have to take like 5 or 6 days where you're not going to be driving like if you're going on vacation you don't come home to having a car with a dead battery and that you don't have to spend 10 minutes disassembling parts on your car just to unplug it

Works perfect. It is compatible with my Viofo A229Pro. The power is adjustable on the box itself and has a small LED to show voltage output. 10 foot is just the right length and has enough slack for adjustment. The value for the quality of the product is spot on and recommend this for anyone to purchase.

I hardwired the dashcam into the fusebox. In a 2012 Tundra, there are two. I used the one under the hood. It took 2 hours and I didn't know if I got it right. I think it worked, but Meee. I bought this one and it was installed in 20 minutes or less. Plug it in and it works. The voltage indicator is really great. No worries about the battery dying. DO NOT GET THE HARD WIRE KIT! GET THIS. Save yoursellffffff!

Update: Auto shutoff doesn’t work My hybrid’s battery started dying after a few months of use and it led to a little more research after having to jumpstart my car a few times. It’s like what a few others said. It doesn’t shut off power when voltage dropped to below 12.4V. The dash cam is still on! Firstly, the OBD port is typically at the lower left below the wheel where you rest your foot, which makes cable routing just as nice as hardwiring. This took me less than 5 minutes to setup, including tucking the cable into trims. Other adapters on Amazon typically has a switch toggle between accessory (on while driving) and always on (cut off at 11.6V). Those can be problematic for hybrid/modern cars. ( See P.S) Instead, this Vantrue OBD adapter is always on, allowing you to select the voltage, it then cuts off power 5 minutes after it drops below the set cutoff. 12.4V: Close to ACC, since it’s easy for the voltage to fluctuate below it, triggering the shutdown. 12V: Around 50% drain, on my car and dashcam it’s 2 hours of low resolution recording or 1.5 days of collision detection (with quick boot) 11.6V: The battery is almost dead. You might only have one start left. I don’t use this. Sat in the car, parking mode triggered as expected. The12.4V and 12.0V to work exactly as advertised. It’s really nice that it shows the set voltage for a moment when the cutoff voltage is changed, giving you confidence that it’s set correctly. I typically leave it at 12.4V, turn it into 12V mode when I’m parked in a higher risk area. It’s also really nice to have a live reading of battery voltage because of this adapter. I think the $10+ premium is totally worth it, this is a much better product than the two mode OBD adapters. Small wishes for future versions: - Having the USB-C cable on top and OBD at the bottom probably makes more sense for most cars? - Bigger toggle switch so it’s easier to flip. - Only having metal pins for 4,5 and 16 so it’s dead sure that it doesn’t have ability read/write to the OBD port. P.S. In typical adapters, ACC detection relies on guessing the car’s on/off state through voltage fluctuations. That’s prone to errors and didn’t work on my hybrid. Tried a few other adapters before this, all had weird issues like the controller cutting off power in the middle of a drive or that it just kept drawing power after the car turned off.
