New images from Giga Nevada suggest that Tesla may be looking to develop a mobile “Megacharger” system for the upcoming Class 8 all-electric Semi. The system seems to be powered by Powerpack batteries. 

To clarify, the “Megacharger” is the name of the Semi’s charging infrastructure, as mentioned by CEO Elon Musk during the vehicle’s unveiling in late 2017. Pictures shared with Teslarati show Tesla’s progress with the buildout of Megachargers at Giga Nevada–and maybe a little more. There are a least two Megachargers at the Gigafactory, and Tesla might install more in the future, especially as the Semi’s limited production starts rolling. 

However, right behind the Megachargers is a trailer with four Tesla Powerpacks and two urban charger stalls. According to Teslarati’s source, there were two trailers at Giga Nevada, and one of the trailers was fitted with Tesla Powerpacks, which may hint at a potential portable charging system.

Tesla’s Mobile Charger Solutions

Tesla has deployed mobile EV charging systems in the past. In 2019, Tesla deployed mobile Superchargers powered by Megapacks for the holidays. It was a simple and practical solution to increase the number of charger stalls at select Supercharger stations quickly and efficiently. Reports then indicated that the Megapack-powered mobile Superchargers could charge about 60-100 vehicles thanks to the Megapack’s 3 MWh capacity.

Mobile “Megachargers” would be a practical move for Tesla and the Semi’s clients. Mobile “Megachargers” could help top-up Semis in popular transport routes while Tesla concentrates on growing its Supercharger Network and the Semi’s dedicated charging infrastructure. Mobile “Megachargers” could also be a cost-effective way for Tesla and the Semi’s clients to ensure that chargers are present for the Class 8 electric truck in locations where they are needed the most.

The Semi’s “Megacharger” Evolution

In 2018, a Tesla Semi prototype sighted in Des Moines, IA was spotted using an ad hoc “Megacharger” system that utilized 5 Supercharger V2 stalls. By 2020, sightings of the electric Class-8 revealed an updated ad hoc “Megacharger” solution that used only 2 Supercharger stalls. It was unknown whether the two stalls charging the Semi in 2020 were V2 or V3 Superchargers. 

The trailer in the picture recently shared with Teslarati held two urban chargers, suggesting a potentially similar charging setup as the Semi prototype spotted in 2020. As for the use of Powerpacks instead of larger Megapacks, it might be down to cost.

Tesla Semi’s updated ad-hoc Megacharger setup hints at vastly improved battery unit

According to Elon Musk during a 2021 interview with noted podcast host Joe Rogan, the Semi’s 300-mile variant should be equipped with a battery pack that’s around 500 kWh. Previous estimates suggested that the Semi will be fitted with a 600 kWh battery pack for the 300-mile version and a 1 MWh battery pack for the 500-mile Semi variant. 

One Megapack has a capacity of 3 MWh and costs about $1.2 million as of July 2021, when Tesla updated the Megapack’s order page. A single Megapack could potentially charge several Semis consecutively, but the costs for such a solution would be substantial. Considering that one Tesla Powerpack has a capacity of up to 232 kWh, four units of the commercial-grade battery would likely have about ~900 kWh of energy capacity. This would likely be enough to top up a couple of Semis at a time, without requiring the full costs of a Megapack-powered system.

Tesla puts Giga Berlin in Plaid Mode with new massive investment

The facility, Tesla’s first in Europe, opened in 2022 and has become a cornerstone for Model Y production and, increasingly, in-house battery manufacturing. Recent announcements highlight a dual focus on scaling vehicle output and advancing vertical integration through 4680 battery cells.

Tesla is pushing forward with significant upgrades at its Gigafactory Berlin-Brandenburg in Grünheide, Germany, signaling renewed confidence in its European operations despite past market challenges.

The facility, Tesla’s first in Europe, opened in 2022 and has become a cornerstone for Model Y production and, increasingly, in-house battery manufacturing. Recent announcements highlight a dual focus on scaling vehicle output and advancing vertical integration through 4680 battery cells.

In April, plant manager André Thierig announced a 20 percent increase in Model Y production starting in July, following a record Q1 output of more than 61,000 vehicles. To support the ramp-up, Tesla plans to hire approximately 1,000 new employees beginning in May and convert 500 temporary workers to permanent positions.

The move is expected to lift weekly production significantly, addressing rebounding demand in Europe after a challenging 2025.

The expansion builds on earlier progress. In 2025, Tesla secured partial approvals to add roughly 2 million square feet of factory space, raising potential annual vehicle capacity from around 500,000 toward 800,000 units, with longer-term ambitions approaching one million vehicles per year. Logistical improvements, new infrastructure, and battery-related facilities are already underway on company-owned land.

Battery production is the latest major focus. On May 12, Thierig revealed an additional $250 million investment in the on-site cell factory. This more than doubles the planned 4680 battery cell capacity to 18 gigawatt-hours annually—up from the 8 GWh target set in December 2025—while creating over 1,500 new battery-related jobs.

Total cell investments at the site now exceed previous figures, bringing the factory closer to full vertical integration: cells, packs, and vehicles produced under one roof. Tesla describes this as unique in Europe and a step toward stronger supply chain resilience.

The plans come amid regulatory and community hurdles. Earlier expansion proposals faced protests over environmental concerns and water usage, leading to phased approvals beginning in 2024. Tesla has navigated these by emphasizing sustainable practices and economic benefits, including thousands of local jobs in Brandenburg.

With nearly 12,000 employees already on site and production steadily climbing, Gigafactory Berlin is poised for growth. The combined vehicle and battery expansions position the plant as a key hub for Tesla’s European ambitions, potentially making it one of the continent’s largest manufacturing complexes if local support continues.

As EV demand recovers, these investments underscore Tesla’s commitment to scaling efficiently in Germany while addressing regional supply chain needs.

Honda gives up on all-EV future: ‘Not realistic’

Mibe believes the demand for its gas vehicles is certainly strong enough and has changed “beyond expectations.” As many drivers went for EVs a few years back, hybrids are becoming more popular for consumers as they offer the best of both worlds.

Honda has given up on a previous plan to completely changeover to EVs by 2040, a new report states. The company’s CEO, Toshihiro Mibe, said that the idea is “not realistic.”

Mibe believes the demand for its gas vehicles is certainly strong enough and has changed “beyond expectations.” As many drivers went for EVs a few years back, hybrids are becoming more popular for consumers as they offer the best of both worlds.

Mibe said (via Motor1):

“Because of the uncertainty in the business environment and also the customer demand, is changing beyond our expectation and, therefore, we have judged that it’ll be difficult to achieve. That ratio [100-percent electric in 2040] is not realistic as of now. We have withdrawn this target.”

Instead of going all-electric, Honda still wants to oblige by its hopes to be net carbon neutral by 2050. It will do this by focusing on those popular hybrid powertrains, planning to launch 15 of them by March 2030.

Honda will invest 4.4 trillion yen, or almost $28 billion, to build hybrid powertrains built around four and six-cylinder gas engines.

There are so many companies abandoning their all-electric ambitions or even slowing their roll on building them so quickly. Ford, General Motors, Mercedes, and Nissan have all retreated from aggressive EV targets by either cancelling, delaying, or pausing the development of electric models.

Early-decade pledges from multiple brands proved overly ambitious as infrastructure lags, battery costs remain high in some markets, and many buyers prefer hybrids for their convenience and range. Toyota has long championed hybrids, while others have quietly extended internal-combustion timelines.

For Honda—historically known for reliable gasoline engines—this shift leverages its core strengths while buying time to refine electric technology. Whether the hybrid-heavy strategy will protect market share in an increasingly competitive landscape remains to be seen, but one thing is clear: the gas engine is far from dead at Honda, unfortunately.

Delta Airlines rejects Starlink, and the reason will probably shock you

In a pointed exchange on X, Elon Musk defended SpaceX’s uncompromising approach to Starlink’s in-flight internet service, explaining why Delta Air Lines walked away from a deal.

Delta Airlines Airbus photographed April 2024 Delta-owned. No expiration date, unrestricted use.

SpaceX frontman Elon Musk explained on Wednesday why commercial airline Delta got cold feet over offering Starlink for stable internet on its flights — and the reason will probably shock you.

In a pointed exchange on X, Elon Musk defended SpaceX’s uncompromising approach to Starlink’s in-flight internet service, explaining why Delta Air Lines walked away from a deal.

Delta rejected Starlink because it insisted on routing all connectivity through its branded “Delta Sync” portal rather than allowing a simple Starlink experience.

Instead, the airline partnered with Amazon’s Project Kuiper—rebranded as Amazon Leo—for high-speed Wi-Fi on up to 500 aircraft, with rollout targeted for 2028. At the time of the announcement, Kuiper had roughly 300 satellites in orbit, while Starlink operated more than 10,400.

The use of the “Delta Sync” portal would not work for SpaceX, as Musk went on to say that:

“SpaceX requires that there be no annoying ‘portal’ to use Starlink. Starlink WiFi must just work effortlessly every time, as though you were at home. Delta wanted to make it painful, difficult and expensive for their customers. Hard to see how that is a winning strategy.”

Musk doubled down in a follow-up post:

“Yes, SpaceX deliberately accepted lower revenue deals with airlines in exchange for making Starlink super easy to use and available to all passengers.”

SpaceX has structured its airline agreements to prioritize zero-friction access—no captive portals, no SkyMiles logins, no paywalls or ads blocking basic connectivity.

While this means forgoing higher-margin deals that would let carriers monetize the service more aggressively, it ensures Starlink feels like home broadband at 35,000 feet. Passengers on partner airlines such as United, Qatar Airways, and Air France have already praised the service for enabling seamless video calls, streaming, and work mid-flight without interruptions.

Delta’s choice reflects a different philosophy. By keeping Wi-Fi behind its Delta Sync ecosystem, the airline aims to drive loyalty program engagement and control the digital passenger journey. Yet, critics argue this short-term control comes at the expense of immediate competitiveness.

Airlines already installing Starlink are pulling ahead in customer satisfaction surveys, while Delta passengers face years of reliance on slower, legacy systems until Leo launches.

SpaceX’s decision to trade revenue for simplicity will pay off in the longer term, as Starlink is already positioning itself as the default high-speed option for carriers that value passenger satisfaction over incremental fees.

Musk’s focus on creating not only a great service but also a reasonable user experience highlights SpaceX’s prowess with Starlink as it continues to expand across new partners and regions.
