A dash cam is a crucial device for any driver, providing a visual record of events on the road. However, powering a dash cam can sometimes be tricky. Using a Dash Cam Obd2 Adapter is a smart solution that allows you to power your dash cam directly from your vehicle’s OBD2 port, ensuring continuous recording even when the car is parked. This article explores different options for powering your dash cam, including using a dash cam OBD2 adapter, and how to choose the right solution for your needs.
One common concern with always-on cigarette lighters is battery drain. A dash cam OBD2 adapter with a low-voltage cutoff switch offers a solution. This type of adapter protects your car battery by cutting off power to the dash cam when the voltage drops below a certain threshold, typically around 11.6 volts. Several brands offer these adapters, often marketed as “battery savers,” and they’re readily available online.
For vehicles where the cigarette lighter is only active when the engine is running, a dedicated dash cam OBD2 power supply is a viable option. These devices plug directly into the OBD2 port and provide continuous power to the dash cam, even when the engine is off. They often include a low-voltage cutoff feature for battery protection. These adapters are generally inexpensive and widely available.
Another approach for cars with switched cigarette lighters involves using both a dash cam OBD2 adapter and a cigarette lighter adapter. Run a USB cable from the dash cam to a convenient location under the dash. When parked, use the OBD2 adapter for parking mode recording. While driving, use a cigarette lighter adapter for power. This provides flexibility and ensures continuous recording.
If your vehicle has an always-on cigarette lighter, consider a heavy-duty splitter with a minimum 10-amp rating. Connect a battery saver adapter to one port, then plug a high-quality cigarette lighter to USB adapter into the battery saver for the dash cam. This setup allows you to power your dash cam while retaining the ability to charge other devices using the second port on the splitter.
Using a dash cam OBD2 adapter doesn’t interfere with using the OBD2 port for diagnostic purposes. Simply unplug the adapter when you need to connect a code reader or scanner. OBD2 ports are designed to handle up to 4 amps, more than sufficient for most dual-dash cam setups, which typically draw 2 amps or less. Therefore, powering a dash cam through the OBD2 port won’t overload the system.
