*Range per hour varies by model, temperature, and state of charge. **Mobile Connector amperage depends on plug adapter/circuit. ***Where offered; check connector compatibility.
For best performance, use a dedicated circuit sized to your target amperage (e.g., 60A breaker for 48A charging). We recommend hiring a licensed electrician for site survey, permits, code-compliant install, and commissioning.
