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

Tesla Megapacks chosen for 548 MWh energy storage project in Japan
Tesla plans to supply over 100 Megapack units to support a large stationary storage project in Japan, making it one of the country’s largest energy storage facilities.
Tesla’s Megapack grid-scale batteries have been selected to back an energy storage project in Japan, coming as the latest of the company’s continued deployment of the hardware.
As detailed in a report from Nikkei this week, Tesla plans to supply 142 Megapack units to support a 548 MWh storage project in Japan, set to become one of the country’s largest energy storage facilities. The project is being overseen by financial firm Orix, and it will be located at a facility Maibara in central Japan’s Shiga prefecture, and it aims to come online in early 2027.
The deal is just the latest of several Megapack deployments over the past few years, as the company continues to ramp production of the units. Tesla currently produces the Megapack at a facility in Lathrop, California, though the company also recently completed construction on its second so-called “Megafactory” in Shanghai China and is expected to begin production in the coming weeks.

Tesla’s production of the Megapack has been ramping up at the Lathrop facility since initially opening in 2022, and both this site and the Shanghai Megafactory are aiming to eventually reach a volume production of 10,000 Megapack units per year. The company surpassed its 10,000th Megapack unit produced at Lathrop in November.
During Tesla’s Q4 earnings call last week, CEO Elon Musk also said that the company is looking to construct a third Megafactory, though he did not disclose where.
Last year, Tesla Energy also had record deployments of its Megapack and Powerwall home batteries with a total of 31.4 GWh of energy products deployed for a 114-percent increase from 2023.
Other recently deployed or announced Megapack projects include a massive 600 MW/1,600 MWh facility in Melbourne, a 75 MW/300 MWh energy storage site in Belgium, and a 228 MW/912 MWh storage project in Chile, along with many others still.

Elon Musk responds to Ontario canceling $100M Starlink deal amid tariff drama
Ontario Premier Doug Ford said, opens new tab on February 3 that he was “ripping up” his province’s CA$100 million agreement with Starlink in response to the U.S. imposing tariffs on Canadian goods.
Elon Musk company SpaceX is set to lose a $100 million deal with the Canadian province of Ontario following a response to the Trump administration’s decision to apply 25 percent tariffs to the country.
Starlink, a satellite-based internet service launched by the Musk entity SpaceX, will lose a $100 million deal it had with Ontario, Premier Doug Ford announced today.
Starting today and until U.S. tariffs are removed, Ontario is banning American companies from provincial contracts.
Every year, the Ontario government and its agencies spend $30 billion on procurement, alongside our $200 billion plan to build Ontario. U.S.-based businesses will…

Ford said on X today that Ontario is banning American companies from provincial contracts:
“We’ll be ripping up the province’s contract with Starlink. Ontario won’t do business with people hellbent on destroying our economy. Canada didn’t start this fight with the U.S., but you better believe we’re ready to win it.”
It is a blow to the citizens of the province more than anything, as the Starlink internet constellation has provided people in rural areas across the globe stable and reliable access for several years.
Musk responded in simple terms, stating, “Oh well.”
Oh well https://t.co/1jpMu55T6s
— Elon Musk (@elonmusk) February 3, 2025
It seems Musk is less than enthused about the fact that Starlink is being eliminated from the province, but it does not seem like all that big of a blow either.
As previously mentioned, this impacts citizens more than Starlink itself, which has established itself as a main player in reliable internet access. Starlink has signed several contracts with various airlines and maritime companies.
It is also expanding to new territories across the globe on an almost daily basis.
With Mexico already working to avoid the tariff situation with the United States, it will be interesting to see if Canada does the same.
The two have shared a pleasant relationship, but President Trump is putting his foot down in terms of what comes across the border, which could impact Americans in the short term.
