Tesla's Buffalo, New York facility has produced its last V3 Supercharger cabinet, marking the end of a seven-year production run. The company is now fully transitioning to V4 cabinets at Giga New York. This shift supports higher power outputs and network expansion.
On March 16, 2026, Tesla Charging confirmed that its Giga New York facility in Buffalo, New York, completed production of its final V3 Supercharger cabinet. Over the past seven years, the plant manufactured more than 15,000 V3 units, which powered the Supercharger network with up to 250kW charging speeds for Tesla vehicles worldwide. These cabinets converted utility power into high-speed DC current for battery charging behind the scenes at Supercharger sites. Tesla Charging noted, “Gigafactory New York built their last V3 Supercharger cabinet, marking the end to 15k+ V3 cabinets over 7 years. V4 cabinet line is ramping up!” Max de Zegher, a director for Tesla Charging, stated, “All in on V4 cabinets! So cool to see how far we’ve come from V1. The brand new V4 cabinet line at Giga New York is automotive-grade and spooling up for charging ubiquity around the world.” Going forward, Giga New York will produce only V4 cabinets. The V4 design offers upgrades including up to 500kW peak charging for cars and 1.2MW for Tesla Semi, supporting 400V-1000V vehicle architectures. S3XY vehicles maintain 250kW rates, enabling up to 200 miles of range in 15 minutes. Each V4 cabinet powers eight stalls—twice as many as before—with lower footprint and complexity for faster deployments. It is the cheapest Supercharger to deploy at under $40,000 per stall, featuring next-generation power electronics that are three times denser for higher throughput and lower costs, plus improved reliability. V4 stalls include cables three feet longer. The automotive-grade V4 supports Tesla's network opening to other manufacturers and larger vehicles like the Cybertruck.
