Intelligent chip low-voltage protection with switch, easy to install, plug and play, capable of real-time and accurate detection of car battery level, overcurrent protection, short circuit protection, suitable for retrofitting 5V on-board equipment such as driving recorders and GPS navigators Specifications: ACC mode Input: 12.8V-36V | Output: 5V/3A Surveillance mode Input: 11.6V-36V | Output: 5V/3A Extension cable: 3.5meter (11.5 ft) length Interface:Type C USB Mode 'O': ACC mode, ACC power/power off button, automatically turns off the power after 5 minutes, and errors may occur for different models, mostly around 5 minutes. Mode '—': Monitoring mode: When your car's ACC is turned off, the OBD power cord will continue to operate until it detects that the car battery voltage is 11.6V (low voltage), and it will turn off after 30 seconds. The low voltage protection of mode '-' can protect the car from the impact of battery depletion, and there is enough voltage to start the car for the next drive in gear. Package includes: 1*OBD to Type C USB charging cable See moreType C USB interface port 3.5m dash cam Type C charger power cord, input port: suitable for all vehicles with OBD port (cars, trucks, ships, ferries, etc.); Output port: designed for Type C port devices such as car recorders, GPS navigators, mobile phone charging, DVRs, radar detectors. OBD2 dash cam power cable is equipped with an intelligent program control chip, which automatically detects battery voltage and provides low voltage protection. When the battery voltage drops below 11.6V, the power output is automatically cut off to ensure normal vehicle startup. Dual working mode; Mode "O", ACC mode: Mode "O" ACC mode - When the car is ignited, the power cord begins to output power; After the car is turned off for 5 minutes, the power cord will automatically stop supplying power and turn off the output. Mode "-"; Monitor the working mode, with the power cord continuously supplying power for 24 hours, and maintain operation until low battery voltage (11.6V) is detected. Plug and play, do not destroy the original car circuit. This charging cable can be directly inserted into the OBD2 port of the car. Use a USB socket to charge the device. Only obtain power from the ODB interface and do not interfere with other ODB data communication. OBD2 dash cam power cord provides 24-hour continuous power supply and steadily reduces the voltage from DC12-36V to 5V/3A, allowing your dash cam to continue working after parking.
