Tesla has officially opened a new Tesla Semi Megacharger station in Southern California. While the company has built Megachargers before, this one is notable because it is the first publicly accessible site not located at a Tesla facility.
The new site, located at 4265 E Guasti Rd in Ontario, California, sits just minutes from Ontario International Airport and near major freight corridors like Interstate 10 and Interstate 15. Its location places it in the heart of one of the busiest logistics regions in North America, where thousands of trucks move goods daily between ports, warehouses, and distribution centers across the Los Angeles area.
The newly opened station is capable of delivering up to 750 kW of charging power, allowing Tesla Semi trucks to quickly replenish their batteries between routes. While Tesla has previously deployed Megachargers at company facilities and partner locations, this Ontario site is the first one open to Tesla Semi customers from multiple fleets.

The Ontario location is also an important milestone for Tesla’s heavy-duty charging infrastructure. It is now the third Megacharger site to appear on Tesla’s map, joining two previously operational locations in California and Nevada.
The first is located in Lathrop, California at 700 D’Arcy Pkwy, and the second in Sparks, Nevada at 1 Electric Ave. Both of those sites support charging speeds of up to 1.2 megawatts.
However, the Ontario station is limited to a maximum of 750 kW. The reason is because it uses Tesla’s MC1 connector, the charging interface used by the current (pre-production) Tesla Semi fleet. Tesla is in the process of transitioning away from this connector as it prepares updated versions of the truck for mass production.
The opening of this station is the start of Tesla’s broader plan to build a large-scale Megacharger network for electric trucking. Tesla has previously indicated it plans to deploy at least 64 Megacharger locations, strategically positioned along major freight corridors across the country.
The infrastructure rollout comes as Tesla prepares to finally begin production of the Tesla Semi, which is being offered in 300-mile and 500-mile range variants at $260,000 and $290,000 respectively. The factory in Nevada is expected to begin production soon, ramping to 50,000 units annually.
