This tiny device works good at allowing me to keep my car’s devices powered while I replace my main battery. This device is super easy to use, just hook up a spare 12v battery to the device via the battery clamps and then once it’s verified that the device is powered by the spare battery, I was able to connect the device’s obd ii connector to the car’s odb connector and the I can go ahead and replace the car battery. Once the car battery is replaced the odb connector can be removed. The second function of the device is the ability to find current leaks; do the same thing to hook the spare battery to the device and then connect it to the car’s odb port and then remove the car’s negative cable from the car battery. Then watch the current value on the device while going through the fuse panel and begin to remove one fuse at a time, once the current value drops the current leak has been found. For my test I knew that my interior lights were on so once I pulled the fuse to cut power to my interior the current dropped so that verified that I found where the car was using battery power. I think this method to find current leaks is pretty easy. All in all I found this car memory saver and current leak detector is a nice and simple device that adds to my troubleshooting tools in my toolbox.

This is a pretty easy one to use, connect the red and black alligator clips to the positive and negative terminals of a spare battery. Turn it on and it will show the voltage of the battery, then plug it into the OBD port under the dash. When you disconnect your main battery then this takes over so you don’t lose programming and computer memory. IF IT WORKED. It literally lasted a minute. I disconnected the main battery, checked back at the OBD memory saver and it was working. Checked on it a minute later and it was off. Got the new battery installed and then disconnected this OBD memory saver, tried to turn it back on. No good. Fuse is fine. Won’t come on. Junk. Spend the extra and buy a better product.
