Review: Works As Described With One Exception - 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. ## Features - Designed to free up your cigarette lighter socket and supply a 24 hours continuous power to your dash camera via OBD connection, enable your dashcam to keep working on after you have parked the car. - Dual working mode switch button integrated for your convenience: 1.ACC working mode,5 minutes off when your car ACC is off; 2.

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. ## Frequently Bought Together - REARMASTER Universal OBD Power Cable for Dash Camera,24 Hours Surveillance/Acc Mode with Switch Button(USB Port) - Garmin 010-02504-00 Dash Cam Mini 2, Tiny Size, 1080p and 140-degree FOV, Monitor Your Vehicle While Away w/ New Connected Features, Voice Control, Black - SanDisk 256GB High Endurance Video microSDXC Card with Adapter for Dash Cam and Home Monitoring systems - C10, U3, V30, 4K UHD, Micro SD Card - SDSQQNR-256G-GN6IA --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ae/products/53062566-universal-obd-power-cable-for-dash-camera-24-hours-surveillance](https://www.desertcart.ae/products/53062566-universal-obd-power-cable-for-dash-camera-24-hours-surveillance) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-05-14*
