The function of OBD Connector Cable Cable with X100Pad3 A80pro Master

Detailed Explanation of the Functions of “OBD Connector Cable Cable with X100Pad3 A80pro Master” (Automotive Diagnostic OBD Power Cable)

The core of OBD Connector Cable Cable with X100Pad3 A80pro Master is to achieve “safe, flexible, and highly adaptable” power extraction through the car’s OBD port. Its 4 core functions can be further broken down into details, covering usage scenarios, technical principles, and practical advantages:

1. Direct Power Extraction: A Modification-Free, Low-Risk Power Solution

• Interface Compatibility: Compatible with OBD or OBD2 ports of over 99% of vehicles on the market (OBD2 is the global mainstream standard since 1996, with a 16-pin trapezoidal interface). No additional drilling or wiring is required; OBD Connector Cable Cable with X100Pad3 A80pro Master can be used immediately after plugging in.

• Safety Advantages: Eliminates risks associated with traditional power extraction methods – no need to connect to the car battery (avoiding short circuits caused by reversed positive and negative poles), no need to disassemble the fuse box (preventing equipment failure due to accidental contact with other circuits), and no need to occupy the cigarette lighter socket (reserving it for other devices).

• Current Stability: Power is drawn directly from the power supply pin of the car’s OBD port (usually 12V/24V standard voltage, consistent with the car battery voltage). The output current is more stable, reducing damage to devices such as dashcams and GPS caused by voltage fluctuations.

2. High Compatibility: Universal Adaptation for Cross-Device and Multi-Interface Use

• Compatible Device Types: Not only supports dashcams, GPS navigators, DVRs (Digital Video Recorders), and radar detectors, but also works with low-power in-vehicle electronic devices such as car air purifiers, car chargers (expanding to USB ports), and in-vehicle surveillance cameras (generally supporting power within 5V/2A; specific parameters depend on the cable specifications).

• Interface Type Coverage: Common standard interfaces include Mini USB (frequently used in older dashcams) and Type-C (the mainstream interface for new devices). Some models also come with a Micro USB adapter to fit more old devices, eliminating the need to purchase an additional conversion cable.

• Voltage Conversion Capability: Built-in DC-DC step-down module can stably convert the 12V/24V voltage from the car’s OBD port to the 5V standard voltage required by devices. This meets the power supply needs of most in-vehicle electronic devices and prevents device burnout due to voltage mismatch.

3. Dual Working Modes: Switch on Demand to Balance “Energy Saving” and “Monitoring”

(1) ACC Mode: Automatic Power Off with Vehicle Start/Stop to Protect the Battery

• Working Logic: Judges the vehicle status by detecting the “ACC signal” (auxiliary power signal of the vehicle ignition switch) from the car’s OBD port. When the vehicle is ignited, the ACC signal is activated, and OBD Connector Cable Cable with X100Pad3 A80pro Master supplies power normally; when the vehicle is turned off, the ACC signal is disconnected, and the cable automatically cuts off power after a delay of about 5 minutes (some models allow setting the delay time, such as 1-10 minutes, via an APP).

• Applicable Scenarios: Suitable for devices that only need to work when the vehicle is running, such as dashcams (recording only during driving) and GPS navigators (no need to work continuously after the vehicle is turned off). This avoids power consumption by devices after the vehicle is turned off and prevents the car battery from being drained.

(2) Constant Power Mode: 24/7 Continuous Power Supply to Support Parking Monitoring

• Working Logic: Does not rely on the ACC signal; instead, OBD Connector Cable Cable with X100Pad3 A80pro Master draws power directly from the “constant power pin” of the OBD port (this pin continues to supply power even when the vehicle is turned off). This enables 24-hour uninterrupted output to meet the all-day working needs of devices.

• Core Purpose: Mainly serves the “parking monitoring function” of dashcams. After the vehicle is turned off, if there is a collision, scratch, window breaking, or other incidents, the dashcam can automatically wake up and record to retain on-site evidence. OBD Connector Cable Cable with X100Pad3 A80pro Master can also be used for all-day recording by in-vehicle surveillance cameras (requiring the device to support low-power mode).

• Power Consumption Control: Some high-end models in constant power mode can automatically detect device power consumption. When the device enters sleep mode, the cable reduces the output current (e.g., from 2A to 0.5A) to further reduce battery consumption.

4. Low-Voltage Protection: Intelligent Prevention of Battery Drain to Ensure Vehicle Startup

• Detection Principle: Equipped with a high-precision voltage detection chip that collects the car battery voltage data in real time every second and compares OBD Connector Cable Cable with X100Pad3 A80pro Master with the preset “protection threshold” (the default threshold for 12V vehicles is mostly 11.6V, and for 24V vehicles, OBD Connector Cable Cable with X100Pad3 A80pro Master is mostly 23.6V; some models allow customizing the threshold via the device or APP).

• Protection Mechanism: When the detected battery voltage is lower than the threshold, OBD Connector Cable Cable with X100Pad3 A80pro Master immediately cuts off the output and stops supplying power to external devices. At this time, the remaining battery power is sufficient to support the normal startup of the vehicle (if the voltage continues to be lower than the threshold, the vehicle may fail to start).

• Power Restoration: After the vehicle is restarted, the battery voltage rises back to the normal range (approximately 13.5-14.5V for 12V vehicles and 27-28V for 24V vehicles). OBD Connector Cable Cable with X100Pad3 A80pro Master will automatically resume power supply, and external devices can continue working without manual restart.
