Alligator Clips: Made of high-quality brass and nickel-plated, they not only have excellent conductivity, but also effectively prevent oxidation and extend the service life. The design not only considers conductivity, but also strengthens the clamping force in the structure to ensure that the battery wires and terminals can be firmly fixed in various application scenarios to prevent accidental loosening. Non-slip Handle: Each alligator clip is equipped with a non-slip plastic handle, which can effectively prevent the clip from slipping due to sweaty hands or slippery environments, and improve the safety of use. The handle is available in red and black, which is not only beautiful, but also helps users quickly distinguish the positive and negative poles. Safe Insulation: The plastic insulation layer is evenly covered on the surface of the alligator clip to prevent current leakage and accidental electric shock. Whether it is high-voltage circuit testing, electronic component welding, or daily battery connection operations, alligator clips can provide reliable insulation protection to ensure the user's safety. Wide application: Whether it is professional electrical engineering, laboratory scientific research testing, or daily maintenance at home, these alligator clips can be used for it. They can not only be used for battery charging and backup battery connection, but also play a role in circuit repair, equipment testing, and power supply detection. Package content: Each set of products contains 6 alligator clips with caps, neatly placed in a transparent plastic storage box for easy carrying and storage. One end of each alligator clip is designed with a tail connection hole plug with a hole diameter of 2mm, and the other end is a pure copper insulated alligator clip with a length of 41.5mm, which allows you to use it worry-free and effortless.
