Close-up look at the Tesla Semi “Megacharger” charging port

Published

on

Tesla’s semi-truck will boast an impressive range of 500 miles per single charge and leverage the company’s newest “Megacharger” for refueling. Similar to Tesla’s global Supercharger network that provides drivers of its passenger vehicles with quick charging access, Megachargers will support truckers by allowing them to recharge their big rig’s battery and travel anywhere in the world while facing little downtime.

According to CEO Elon Musk, Tesla’s ultra high-powered Megacharger will be capable of replenishing 400 miles of range in as little as 30 minutes of charging. However, unlike a Supercharger that has a power output of roughly 120 kW, Tesla’s Megacharger will see more than ten times the power levels.

A close-up look at the semi-truck’s charging port reveals an 8-pin configuration that’s significantly larger than the Supercharger port found on Model S, X, and Model 3 passenger cars.

Tesla notes on its website that the semi-truck will consume “less than 2 kWh / mile”. If we’re to factor in a worst case scenario of 2 kWh of energy used per mile travelled, this would equate to 800 kWh of energy consumed in 400 miles (644 km) of travel. Tesla’s Megacharger would need to have a tremendous power output of 1.6 MW, or thirteen times the power level of a standard Supercharger to be able to replenish 400 miles of battery range in 30 minutes. This, of course, is based on the assumption that the Tesla Semi will consume 2 kWh of energy per mile which in reality will probably be less, as Tesla notes.

Regardless, Tesla’s Megacharger will likely see over 1 MW of power.

We asked our friend KManAuto, who had the opportunity to get an up-close view of the Tesla Semi Megacharger port, how the company might be able to support such power levels.

“I think they increased the voltage, for simplicity probably doubled it. keeps the wire size down. Less heat build up. The charge port on the semi also has eight pins for charging. Of course, positive and negative, means it’s like having four normal Superchargers plugged in.” says Kman. “So if it was for normal Superchargers through the same size pins it would be approximately 500 kW due to wire size. If they double the voltage, they could run twice the amount of power through the same wires, meaning they would be able to hit 1.6 MW.”

We’ve embedded a great video below from Kman showing the location and size of the Tesla Semi’s charging port.

Tesla did not provide a date on when the Megacharger network would be added, but we do know that first production of the Tesla Semi is slated for sometime in 2019.

NASA and SpaceX are targeting July 31 for the launch of Crew-11, the next crewed mission to the International Space Station (ISS). The flight will lift off from Launch Complex 39A at Kennedy Space Center in Florida, using the Crew Dragon Endeavour and a Falcon 9 booster.

Crew Dragon Endeavour returns

Crew-11 will be the sixth flight for Endeavour, making it SpaceX’s most experienced crew vehicle to date. According to SpaceX’s director of Dragon mission management, Sarah Walker, Endeavour has already carried 18 astronauts representing eight countries since its first mission with NASA’s Bob Behnken and Doug Hurley in 2020, as noted in an MSN report.

“This Dragon spacecraft has successfully flown 18 crew members representing eight countries to space already, starting with (NASA astronauts) Bob (Behnken) and Doug (Hurley) in 2020, when it returned human spaceflight capabilities to the United States for the first time since the shuttle retired in July of 2011,” Walker said.

For this mission, Endeavour will debut SpaceX’s upgraded drogue 3.1 parachutes, designed to further enhance reentry safety. The parachutes are part of SpaceX’s ongoing improvements to its human-rated spacecraft, and Crew-11 will serve as their first operational test.

The Falcon 9 booster supporting this launch is core B1094, which has launched in two previous Starlink missions, as well as the private Ax-4 mission on June 25, as noted in a Space.com report.

The four-members of Crew-11 are NASA astronauts Zena Cardman and Mike Fincke, as well as Japan’s Kimiya Yui and Russia’s Oleg Platonov.

Tight launch timing

Crew-11 is slated to arrive at the ISS just as NASA coordinates a sequence of missions, including the departure of Crew-10 and the arrival of SpaceX’s CRS-33 mission. NASA’s Bill Spetch emphasized the need for careful planning amid limited launch resources, noting the importance of maintaining station altitude and resupply cadence.

“Providing multiple methods for us to maintain the station altitude is critically important as we continue to operate and get the most use out of our limited launch resources that we do have. We’re really looking forward to demonstrating that capability with (CRS-33) showing up after we get through the Crew-11 and Crew-10 handover,” Spetch stated.

EV fans urge Tesla to acquire Unplugged Performance for edge in fleet and security industry

Unplugged Performance has built a name for itself by producing performance upgrades for Tesla vehicles.

A growing number of Tesla enthusiasts and longtime community voices are calling on the electric vehicle maker to acquire Unplugged Performance, a California-based aftermarket company best known for tuning Tesla vehicles and developing specialized government fleet solutions under its UP.FIT division.

The idea was once considered a niche proposal among EV fans, but it is now gaining serious attention not just as a performance play but as a strategic move to deepen Tesla’s roots in the fleet and security industry. 

A strategic fit

Unplugged Performance has built a name for itself by producing performance upgrades for Tesla vehicles, from track-optimized components to visual and aerodynamic upgrades. But in recent years, its UP.FIT division has pivoted toward a more functional future by outfitting Tesla vehicles like Model Ys for police, military, and government use.

That work has sparked growing calls for closer collaboration with Tesla, especially as the EV maker increasingly leans into autonomy, AI, and fleet services as core components of its next chapter.

“I posted this four years ago, but I think it’s more true now than ever,” wrote Whole Mars Catalog, a well-known Tesla investor and FSD Beta tester, on X. “Tesla should buy Unplugged. But not just as a Performance division. What they are doing with UP.FIT unlocks large government and commercial fleet purchases that can improve utilization.”

Tesla fans such as shareholder Sawyer Merritt echoed the sentiment, calling Unplugged a “great fit within Tesla.” adding, “They are literally located directly next to Tesla’s design studio in Hawthorne.”

Enabling the next wave

Supporters of the idea noted that integrating Unplugged into Tesla’s corporate structure could help accelerate the adoption of autonomous technologies in government sectors. With UP.FIT patrol cars already in use across some U.S. police departments, Tesla fans envisioned a future where self-driving Teslas could potentially revolutionize law enforcement, search-and-rescue, and public service logistics.

“Just imagine how autonomous patrol cars could transform policing and bring us into a safer future,” the veteran FSD tester wrote.

The benefits could also extend to Tesla’s existing consumer base. “They also have some incredible products in the works that I think will appeal to many ordinary Tesla drivers — not just those looking for performance or mods. Stuff that’s so good it should have come straight from the design studio next door,” Whole Mars Catalog noted.

Unplugged Performance, founded in 2013, shares not just a product vision with Tesla, but also geography. Its Hawthorne headquarters sits directly adjacent to Tesla’s design studio, and the two companies have maintained a close working relationship over the years. The aftermarket firm has long positioned itself as a “mission-aligned” partner to Tesla.

In response to the recent calls for acquisition, Unplugged Performance acknowledged the support from the community. “Our very existence is to support the Tesla mission with @UpfitTesla and @UnpluggedTesla,” Unplugged CEO Ben Schaffer posted on X. “We love working with Tesla and are grateful for the community’s support since 2013!”

Tesla has begun rolling out Grok, an in-car conversational AI assistant developed by xAI, to eligible vehicles starting July 12. The feature marks the most direct integration yet between Elon Musk’s artificial intelligence startup and Tesla’s consumer product lineup, offering drivers hands-free access to a chat-style companion while on the road.

Grok comes pre-installed on new vehicles

According to Tesla’s FAQ page for the feature, all new vehicles delivered on or after July 12, 2025, will include Grok AI out of the box. Owners of older vehicles may gain access through an over-the-air update, provided their vehicle meets a few hardware and software requirements.

Specifically, Grok is currently only supported on Tesla models equipped with an AMD infotainment processor and running vehicle software version 2025.26 and higher. Compatible models include the Model S, Model 3, Model X, Model Y, and Cybertruck. A Premium Connectivity subscription or active Wi-Fi connection is also required.

Tesla notes that additional vehicle compatibility may arrive in future software updates.

Grok’s features and limitations for now

Drivers can engage with Grok using the App Launcher or by pressing and holding the voice command button on the steering wheel. Grok is designed to answer questions and hold conversations using natural language, offering responses tailored to its chosen personality—ranging from “Storyteller” to the more eccentric “Unhinged.”

For fun, Tesla posted a demonstration of Grok likely running on “Unhinged” talking about what it would do to Optimus when they are on a date, much to the shock of the humanoid robot’s official social media account.

It should be noted, however, that Grok cannot currently issue commands to the vehicle itself, at least for now. Traditional voice commands for tasks like climate control, navigation, or media remain separate from Grok as of writing.

The feature is being released in Beta and does not require a Grok account or xAI subscription to activate, although that policy may change over time.

Grok privacy and in-car experience

Tesla emphasizes that interactions with Grok are securely processed by xAI and not linked to a user’s Tesla account or vehicle. Conversations remain anonymous unless a user signs into Grok separately to sync their history across devices.

Tesla has also begun promoting Grok directly on its official vehicle webpages, showcasing the feature as part of its in-car experience, further highlighting the company’s increasing focus on AI and infotainment features on its all-electric vehicles.
