Review: You'll need this... even if it's just to loan to your friend. - Great practical product and good build quality. I just used it to replace the battery on my wife's Lexus. Modern cars have so much computer tech and lots of codes, settings, and presets can be lost when the battery is disconnected. I used my solar generator to connect a 12 volt source, but you can use another car battery, an AC 12 volt source, or a small battery pack with 8 AA's. But the reason it has a long cord is to reach another car's 12 volt receptacle as you attach to your OBD port. With this method one can also charge the existing battery, or jump start your car without dealing with jumper cables. Great product to stash in your car for when you need it, and you'll need it. Review: worked well - worked well ## Features - 10 amp fuse built into the memory saver, better reliable on overload protection.Obd memory saver powered by any jump starter with a 12V outlet into an OBD II Memory Saver. Interface connector between a 12V DC power source and vehicle's OBD II port. Preserves vehicle codes and electronic presets. Replacing a car battery on older vehicles used to be simple!! You unhook the old battery and install the new one. - Late-model vehicles, however, rely on computers that operate everything from the stereo to the transmission. If power is lost to the computer, the settings are lost and have to reset to default. That means the vehicle may feel different when driven, and you may have to enter a security code to access the stereo. - Using this simple memory saving device when replacing your car battery will help you avoid these problems. This device can work with any 12V DC power source, including jump starter, DC 12V Lead-acid battery, or another car’s DC 12V power outlet. - As our device with 3 meter cable, it will be a convenient way, should you not have jump starter (or Lead-acid battery) on hand, and the device can also get the 12v power supply from cigarette lighter of another good car. Just insert the Cigarette lighter plug to this car and insert into 16 pin plug to the OBD port of the car you want to replace battery. And now you can replace the battery. - Compared by most of OBD metal pins in market with zinc plating, ours are gold plating. Better reliable on contact and electric transmission. Compared by most of OBD II Memory Saver (or Automotive Computer Memory Saver) in market with 3 ~ 5 ft in cable length, ours with super long 10 ft (3meters) cable. In this way, you can change your car battery, also by get the alternative 12V power source from another car, when you not have a jump starter on hand. ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | JHT | | Brand | Jtron | | Item Weight | 9.9 ounces | | Package Dimensions | 7.09 x 5.83 x 2.6 inches | | Is Discontinued By Manufacturer | No | | Manufacturer Part Number | GTT5-9 | ## Images ![OBD2 Car Memory Saver 2 in 1, Vehicle ECU Emergency Power Supply Cable with Alligator Clip-On 12V Car Battery Cigarette Lighter Power Extension Socket - Image 1](https://m.media-amazon.com/images/I/61xueGenbNL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ You'll need this... even if it's just to loan to your friend. *by R***X on January 25, 2026* Great practical product and good build quality.
