Engineered for the most demanding industrial applications, this heavy-duty booster pack delivers an incredible 5250A of starting power.

The unit features a robust exterior built to withstand the rigors of a professional garage or outdoor job site. Despite its immense power output, it maintains the signature safety standards of the brand, protecting against sparks and reverse polarity to ensure secure operation in high-stakes recovery situations.

This model also functions as a high-capacity power hub, equipped with multiple output ports to support a wide range of peripheral equipment. Its internal battery chemistry is optimized for longevity and thermal stability, providing consistent performance even in extreme weather conditions where traditional lead-acid boosters often fail.
