You turn the key. Click. Click. Nothing. Your battery is dead. You have a portable jump starter, but the cable it came with broke, got lost, or never worked right. This EC5 jumper cable gets you moving again. Connect the red clip to your battery‘s positive terminal. Connect the black clip to the negative terminal. Plug the EC5 connector into your jump starter. Start your car. That‘s it. The anti-reverse design prevents you from mixing up the clamps — it only fits one way into the jump starter. The 10 AWG pure copper core and heavy-duty clamps deliver 400A of starting current, enough for cars, SUVs, trucks, and even boats. The PVC jacket stays flexible in freezing weather and won‘t crack after repeated use. Keep one in your trunk. Keep another in your spouse‘s car. Give one to your teenager. When your battery dies, you won‘t be stuck waiting for help — you‘ll already have the fix. Package includes: 1 x EC5 Emergency Power Cable (Red and Black Alligator Clips), 1 x EC5 Connector. Cable length: 30cm (approx. 12 inches). Working voltage: 12V. Wire gauge: 10 AWG. Current rating: 400A. Before ordering: Ensure your portable jump starter has an EC5 female port. Do not use this cable with standard jumper packs that use clamps on both ends — this cable is designed for EC5-compatible jump starters. Remove clips within 30 seconds after starting the vehicle to avoid overheating.
