Memory saver OBD male to Cigarette lighter socket up to 4 meters

Memory saver

Powered by any jump starter with a 12V socket in an OBD II socket.
It can be connected between a 12V DC power source and the vehicle's OBD II port.
Preserves vehicle codes and electronic presets.

However, new vehicles rely on computers to power everything from the stereo to the transmission. If power is lost to the computer, the settings are lost and must be reset to default. This means the vehicle may feel different when driven, and you may need to enter a security code to access the stereo. Using this simple memory-saving device when changing your car battery will help you avoid these problems.

This device can operate with a 12V DC power source, including a jump starter, DC 12V lead-acid battery, or another car's DC 12V outlet.
As our product with 4 meters cable, it is a convenient way, if you don't have jump starter (or lead acid battery) at hand, and the device can also get 12v power supply from cigarette lighter of another good car. Just insert the cigarette lighter plug of this car and insert the 16-pin connector into the OBD port of the car you want to change battery. And now you can change the battery.

Because the typical OBD Auto Memory Saver does not have the protection against wrong polarity (AIP), so it could damage your auto ECU (electronic control unit) if a wrong polarity is input. For our new upgraded version OBD Auto Memory Saver, it has been added the safety function of AIP; If a power input with wrong polarity, the AIP function will automatically take effect (electricity cannot be transferred to your car, if wrong polarity is input); also the LED on the memory saver will not light. So that your car ECU and other electrical appliances are fully protected under wrong power connection.
