1.REVERSE CHARGING Ensure that after the car is started, the speed at which the current flows back to the original power supply vehicle remains within a range, usually below 1A. The pliers connector used in the test clamp can provide a r and more connection, ensuring stable current and avoiding possible sparks or damage 2.GOOD ELECTRICAL CONDUCTIVITY: Copper is a very good conductive material and has good electrical conductivity. Choosing highquality copper materials in the production of battery clips can ensure better conductivity. This means that the battery clip can effectively transmit current when connecting the battery to avoid current loss and energy waste 3.INSULATING SHELL: The insulating shell of the battery clamp is made of highquality ABS plastic, which can provide good insulation performance and aging resistance. This ensures the and reliability of the battery clamp, protecting users and equipment from issues such as current leakage or short circuits 4.APPLICABLE SCENARIOS: When the car battery is out of power and cannot be started, you can use the test cable clamp to connect the battery of another car to increase the voltage so that the car can be started. If the battery voltage is low and needs to be boosted, you can use a test cable clamp to connect the battery to the power supply to increase the voltage
