Tesla Charging announced that the first pre-assembled Megachargers have been deployed to support the ramp of the Tesla Semi. "We're ready to support the Semi ramp," the team wrote on X.

Each unit is a V4 cabinet equipped with two posts, with charging capacity reaching up to 1.2 MW per post. The pre-assembled design suggests a faster deployment timeline compared to traditional on-site construction, streamlining infrastructure readiness as Semi production scales.
