Upgraded OBD2 OBD Power Cable

The OBD emergency power cable is an essential tool for replacing automotive batteries while ensuring the protection of your vehicle's ECU data. This upgraded design features simultaneous voltage and current display, along with multiple safety protections.

Key Features:

• Simultaneous Voltage and Current Display: Equipped with a power management system that shows battery voltage to prevent the use of depleted batteries, ensuring uninterrupted power during battery replacement.
• Over-voltage and Over-current Protection: Features built-in protections against over-current, over-voltage, and reverse polarity, ensuring safe operation.
• Quick Blow Fuse: Includes a 3A quick blow fuse for added safety; power-off protection activates when voltage exceeds 16V.
• Battery Replacement Procedures: Simple steps to connect a fully charged spare battery securely, ensuring correct voltage display before replacing the old battery.
• Leakage Detection: Allows for preliminary diagnosis of automotive leakage by monitoring current flow after unplugging the fuse in the automotive fuse box.

Important Notes:

• During battery replacement, ensure the vehicle power switch remains off; do not open car doors or activate lights.
• The operating voltage range for this device is 10~14V. An alarm will sound if the voltage is below 10V or above 14V.
• Power-off protection will be activated when voltage exceeds 16V.
