12V Reverse-Charge-Proof Jumper Cable

This booster cable is constructed with durable metal alligator clamps and a robust EC5 plug connector, designed specifically for 12V automotive applications. The cable features a built-in reverse charge prevention module to safeguard both the jump starter and vehicle battery from incorrect polarity connections. It is compatible with most portable 12V car jump starters on the market and functions as a reliable replacement or spare set. Installation is fully plug-and-play — simply connect red clamp to positive (+) terminal, black clamp to negative (−) terminal, then insert the EC5 plug into the jump starter’s socket. For safety, always disconnect within 30 seconds after engine start and never allow clamps to touch each other during use.
