<b>Technical Specifications:</b><br> <b>ACC Mode Input: </b>13V-36V | Output: 5V/2.1A <br> <b>Surveillance Mode Input: </b>11.6V-36V | Output: 5V/2.1A<br> <b>Extension Cable: </b>0.5meter(1.64 ft) length<br> <b>Interface: </b> OBD to USB (The USB port can be connected to the power cable of other interfaces. More flexible!)<br><br> The low voltage protection for mode “—” protect your car from running out the battery, enable you have enough voltage to start the car for next driving. <br><br> <b>FAQ: </b><br> Q: What car is this product suitable for?<br> Answer: As long as your car has an OBD Interface, you can use it. Obd of different cars in different positions.<br> Q: How to choose the working mode of OBD power cable? <br> Answer: Press "O" to turn on "ACC" mode, and press "-" to turn on "Surveillance" mode.<br> "ACC" mode: Turn on the car, the OBD cable works. Turn off the car and the OBD cable stops working.<br> "Surveillance" mode：Even if the car is stopped, the OBD cable can continue to work, realizing 24-hour parking monitoring!<br> Q: How can it automatically close?<br> Answer: "ACC" mode: When the input voltage is lower than 13V (12V car) or lower than 25.5V (24V car), the power line will be automatically cut off after a delay of 5 minutes.<br> "Surveillance" mode：When the input voltage is lower than 11.8V (12V car) or lower than 23.6V (24V car), the power line will be automatically cut off after a delay of 8 seconds.<br> Q: Why is the OBD cable shutdown delayed? <br> Answer: Because the air conditioner, headlights, wiper will use the car's battery voltage during the driving process. The voltage of the car's battery is unstable and fluctuates up and down. Avoid When there is a voltage fluctuation, the detection voltage is lower than our 13V detection point, which causes the OBD to be frequently powered off, so a delay of 5 minutes is cut off for all.
