Overview
- The official Tesla Semi account posted video of a charging session peaking at 1.2 megawatts on a Megacharger.
- Program lead Dan Priestley said the run occurred at a dedicated site, described the power as sustained, and noted Nevada factory chargers are 1.2 MW capable.
- A refreshed Semi was filmed at a Megacharger near Giga Nevada with exterior updates that suggest a production-ready design.
- Priestley said the new truck adopts the latest Megawatt Charging System connector after earlier units used an MCS v2.4 design.
- Tesla’s V4 cabinet architecture is rated to deliver up to 1.2 MW, though key unknowns remain on state of charge, charge-curve duration, and site power needs as production targets 2026.
