Universal OBD Power Cable for Dash Camera,24 Hours Surveillance/Acc Mode with Switch Button(USB Port)

This product is working great for my needs. I just needed my dash cam to run while my vehicle is on otherwise the camera will drain my battery. It was easy to install and has been working great for me specific needs. I would say this is much easier than other options out there or trusting a dash cam to shut off on its own.

I have been using Rear master since 2016. It powered My Yi cam, Apeman Cam. And now my Rove R2-4K. It always turns on when you turn the car on and shuts off 2minutes after parking with the off switch. If you want it on all the time just turn it on.

Currently using this in a 2024 Dodge Durango GT Plus with a Rexing V33 Plus dashboard cam.I know V33 comes with a cable that will allow me to power it directly through the fuse panel, but on the Durango, the fuse panel is under the hood. I did not want to have to worry about going through the firewall to connect it.That is when I found this power adaptor.I love that it can be switched from Always On to ACC Only. I have only had it installed for a day now, and I am leaving it at Always On until I see significant drain on the battery.

Instead of shutting off after five minutes, it actually shuts off after about twenty minutes. That's not an issue, just noting the difference. I assume this device is measuring battery voltage to determine when the car is off or running. Charging voltage on a car battery is around 13.5 to 14v (when engine is running). When the car is turned off, the battery is no longer being charged and voltage is just the battery alone @ 12V. I think that's how it works.

I purchased the Mini USB OBD Charger with On/Off Switch. This was the only solution I could find to having the device turn on and off with the car, instead of being on 24x7. I am using this for a Garmin GPS, so there's not a need for it to always be on.First, this is not compatible with a Garmin GPS out of the box. It will power the GPS and turn it on, but it goes into PC/Data mode, not map mode. There's a slight work around where you unplug the GPS really quick and plug it back in, but I didnt want to bother with that.I took the USB cable from my current charger, and cut the top off and cut the end of this one off and soldered it into this OBD adapter. After I did this it worked perfect! It turns on when the car turns on, and when I turn the car off, the GPS turns off 5 min later.I just wish It had Garmin GPS support out of the box, and that the auto off time was alot less, like 30 seconds or something.I would totally buy this again to hardwire a GPS in my other car, but PLEASE be aware it's not plug and play with Garmin. If you're cool with cutting 2 USB cords apart, and soldering them back together then by all means go for it :)

Simple device with a fairly simple job: send power to my dashcam when the ACC is on. Unfortunately it doesn't do what it says.The device cuts power to the dashcam after five minutes, even when the car is running. You have to use the always-on mode, and then deal with the well-reported issues of running your battery down if you forget to turn it off.Will have to return it :(UPDATE: It turns off in ACC mode after several minutes; how long it lasts before shutting down varies every time.UPDATE 2: Ordered another to see if the first was a dud. The product itself is a dud. Same issue w/ power shutting off after random amounts of time.Used on a 2015 Chevy Malibu. Saw another similar product (looks identical, actually) w/ a note buried deep in the description that said something like 'based on customer feedback this product doesn't appear to work with many GM and Toyota vehicles'. If they know that to be true, that information should be much more accessible.

Disclaimer: I've only had this item for one day and done an initial 15 minutes of testing.Another review mentions issues in their model year CR-V, so I was hesitant about this working. I'm glad I ordered it anyhow, because it works just fine (at least for my initial installation and testing) in my 2010 Honda CR-V.The flip switch does indeed control if its ACC ON or Always On, so set as your needs may vary. My dash cam has a standby G sensor battery so I don't like leaving it Always On, as it does present a potential to return to a discharged starter. I just tested which mode the flip switch activated: on is set to always on, the off is for acc on only.I needed this since my year model CR-V removes the DC barrel port and replaces with a built in USB port (carplay supported) for my dash electrical outlet. (It has a barrel port in the cargo area but that only helps for my rear-facing dash cam.) Using a splitter so I can charge phone + dash cam resulted in both being under-powered, so this solved my issue by splitting my dash cam to its own power without my having to tap into the fuse box.

2024 UPDATE: Worked fine with an old Aukey dual camera. My 4K VIOFO dual flickers and continually restarts with this unit. Most high end dashcams draw more power than those from 5 years ago.———Original review:My car's accessory plugin does not shut off, so I needed a solution that did not require major surgery to connect my capacitor-powered Aukey dual dashcam to the fusebox. This did the trick, as my OBD port is easily accessed just under the dashboard. I turn it off when parked at home and keep it on when parking in public places to catch any potential hit and run collision or car prowlers.The 2 times I forgot to turn it off and parked for a couple of days, my 8 cylinder car's battery needed a slight boost to start because of the 11.6 volt cutoff, although it was not drained completely. That should be higher, say 12.2, or adjustable, but I can live with it.The company makes similar units with USB connectors that will plug in directly to webcams (or other devices), but I prefer this setup because it gives me more cable length for routing, and I can easily hook up a USB power bank to my camera out of sight for extended parking monitoring.
