ZKTOOL USB Powered Car ECU Emergency Power Supply Cable, Automotive Memory Saver with Buzzer Alarm, OBD II Plug Connector, Battery Replacement Tool

【New Design】 Introducing the OBD II Memory Saver, a USB-powered battery replacement tool that protects your car's memory and prevents resetting of settings such as dashboard information, digital clock, audio system, memory seats, ABS, and more during the battery replacement process. 【Harm Of Power Outage】 Avoid the danger of power outage during battery replacement without a backup power source, which may cause memory loss and display abnormalities. The repair body may also require re-adjustment at the dealership. With this tool, you don't have to worry about any of that. 【USB Powered】 The Car ECU Emergency Power works in conjunction with a USB power source, such as a fully charged USB power bank, making it more stable and convenient than using alligator clips to connect to a backup power source, significantly reducing operation difficulty. 【Indicator Lights & Buzzer】 The new version of the Memory Saver features three indicator lights and a buzzer that warns you in various situations. The tool runs inside the car, and battery replacement must be carried out in front of the vehicle. The buzzer will remind you when the USB power is low, allowing you to focus on your work. 【High-Quality ABS Material】 Made of ABS material, ensuring high quality and longer lifespan.
