TL;DR
The J1772 connector is the SAE-standard five-pin charging plug for Level 1 and Level 2 AC charging in North America, carrying up to 80 amps at 240 volts along with pilot-signal pins that negotiate current and prevent energizing until fully seated. Nearly every EV sold in the US before the NACS transition accepts it directly, and Tesla vehicles use a simple adapter.
What it means
The J1772 connector is the SAE-standard five-pin charging plug for Level 1 and Level 2 AC charging in North America, carrying up to 80 amps at 240 volts along with pilot-signal pins that negotiate current and prevent energizing until fully seated. Nearly every EV sold in the US before the NACS transition accepts it directly, and Tesla vehicles use a simple adapter. Home charging stations are sold by their J1772 cable or, increasingly, with NACS, so buyers match the connector to their vehicle and rely on adapters across the gap.
