Specifications

Pro-Tip: To ensure maximum amperage delivery, always make sure the clamps are attached to the cleanest part of the battery terminal possible. If the terminals are heavily corroded, use a wire brush to clear a small spot for the jump starter's teeth to bite into—this reduces resistance and ensures your vehicle starts on the first attempt.
