Tesla opens its first public Megacharger — and it's 2.4x more powerful than a Supercharger V4
Tesla has opened its first public Megacharger station in Bloomington, California, giving any Tesla Semi operator — not just fleet giants like PepsiCo — access to high-power truck charging for the first time. The site sits about 50 miles east of Los Angeles in one of Southern California's busiest freight corridors, where cargo flows from Long Beach and the Port of LA toward inland distribution centers. Until now, Semi owners were tied to private depot chargers, limiting where the trucks could realistically operate.
The power behind it
The Bloomington station has six charging posts, each capable of 1.2 MW peak output. To put that in perspective, a Supercharger V4 — Tesla's fastest charger for passenger cars — tops out at 500 kW. One Semi session draws roughly the equivalent of two or three Model S vehicles charging at full speed simultaneously. That scale isn't excess: the Semi's large battery pack is rated for up to 500 miles of range, and slower chargers would strand drivers for hours. With 1.2 MW, Tesla claims 70% range recovery in about 30 minutes — viable for a regulated rest break.
Today, Tesla officially opened the world's first public Megacharger in Bloomington, California, about an hour east of Los Angeles.

The network taking shape
Bloomington is one of two Megacharger stations now live; the other is in Lathrop, CA. But the build-out is accelerating. As Clean Trucking reports, Tesla's map now shows 64 additional planned locations across 15 states — Texas leads with 19, California follows with 17. The original target was 46 stations by early 2027, but a partnership with Pilot Travel Centers (a Berkshire Hathaway subsidiary operating 900+ truck stops) has pushed construction into H1 2026, with Electrek reporting some sites could open as early as summer 2026.
What it means for the market
Rivals including Volvo, Daimler, and Hyliion don't run proprietary charging networks. Most rely on ChargePoint or Electrify America infrastructure, which maxes out at around 350 kW for commercial vehicles — less than a third of Tesla's figure. The Pilot partnership effectively plants Megachargers inside existing truck stop infrastructure, the same playbook Tesla used with Superchargers at highway rest areas. If the rollout holds to schedule, Tesla could control the dominant fast-charging standard for electric Class 8 trucks before competitors have a comparable answer.
For smaller fleet operators who've been watching the Semi from the sidelines, public charging changes the calculus. A truck that can only charge at your own depot is a niche tool; one that can charge on the road starts to look like a viable long-haul workhorse.
