Our JNC311 and JNC318 lithium jump starters are designed to be lightweight but provide powerful starts for dead batteries and to run accessories. If your cables or clamps are worn, our Smart Cable/Clamp Set for JNC311/JNC318 offers a simple solution to provide safe, reliable performance.
Note: it is critical that you only use the proper cable/clamp set designed specifically for your lithium jump starter. This means replacing your cable/clamp with the factory replacement part only. Use of an improperly matched cable/clamp set could result in property damage and/or personal injury.
