There’s been a lot of chatter amongst the EV industry lately about the North American Charging Standard, better known by the initialism “NACS.” The charging standard originally introduced by Tesla is quickly becoming the preferred charging plug and doesn’t seem to be going anywhere anytime soon. All the more reason to stay in the know since your next EV could very well use NACS to charge.

The birth of a new charging standard

Like several of the EV technologies automakers have adopted and implemented today, Tesla paved the way. The American automaker decided to develop its own charging plug en route to establishing a proprietary charging network that would become today’s ultra-reliable Supercharger Network.

Back in 2012 with the launch of the Model S sedan, Tesla first introduced its proprietary charging standard, referred to as the Tesla Charging Connector (brilliant nomenclature, right?). The standard would be adopted for the American automaker’s three proceeding EV models as it continued to implement its Supercharger network around North America and into new global markets where its EVs were being sold.

Still, CCS has held a respectable reign as the inherent standard in EV charging after quickly ousting Japan’s CHAdeMO plug back in the early days of EV adoption when the Nissan LEAF was still a global leader. Since Europe uses a different CCS standard than North America, Tesla’s built for the EU market use CCS Type 2 connectors as an additional option to the existing DC Type 2 connector. As a result, the automaker was able to open up its Supercharger network to non-Tesla EVs overseas much sooner.

Despite years of rumors about Tesla opening up its network to all-EVs in North America, it wasn’t until recently it actually happened. Given that the Supercharger network remains, without argument, the largest and most reliable on the continent, this was a huge win for EV adoption as a whole and has led to the establishment of the NACS as the preferred method of charging.

Tesla charging connector? No, NACS

In the 11 years since the Tesla Supercharger was introduced, its network has grown to over 45,000 charging piles (NACS, and CCS) around the globe. Recently, Tesla began opening up its exclusive network to non-marque EVs thanks to a new adapter it calls the “Magic Dock.”

This proprietary dual connector allows for charging across both NACS and CCS Type 1 plugs and is slowly but surely rolling out to Supercharger stations across the continent. As plans to open its network up to other EVs were coming fruition, Tesla announced it was renaming its charging plug the North American Charging Standard (NACS).

The move quickly drew criticism from legacy automakers going electric, as CCS was still the actual charging standard. Tesla, on the other hand, argued that NACS should be adopted because its adapter is significantly more compact. It also offers more seamless connection and access to the Supercharger network as thousands of piles are being replaced with Magic Docks.

Like many new technologies and ideas, the general population threw out a blend of both skepticism and excitement, but CCS has remained the go to charging standard. However, a startup known for thinking outside the box in EV design offered a catalyst in NACS charging adoption we’re watching just begin to catch fire today.

The industry hops on the NACS hype train

Last summer, solar EV startup Aptera Motors truly got the NACS adoption train rolling before Tesla had even opened up the standard to others. Aptera said it saw the potential in NACS charging and even created a petition to make it the true standard on the continent, garnering nearly 45,000 signatures.

By fall, Aptera was publicly debuting its Launch Edition solar EV, complete with NACS charging with the permission of Tesla. It even added DC fast charging capabilities as the request of its passionate community.

Having Aptera onboard NACS was big for Tesla, but not that big. The startup hasn’t even reached scaled SEV production yet. The real momentum for NACS adoption would come months later when Tesla announced a surprising partnership with a proper rival – Ford Motor Company.

Beginning next year, Ford EV owners will gain access to 12,000 Tesla Superchargers in the US and Canada using an NACS adapter that will be offered directly to them. Furthermore, wew Ford EVs built after 2025 will come with the NACS charging port already integrated into their design, eliminating any need for adapters.

Less than two weeks later, another major American automaker announced a partnership with Tesla to adopt NACS charging – General Motors. GM offered the same strategy as Ford in integrating adapters for initial customers followed by a full NACS integration in 2025. This announcement all but confirmed that NACS is in fact the new standard on the continent and further established the trio as a new “big three” in American EV manufacturing.

Since then, the flood gates have opened, and we’ve seen a press release almost daily from charging networks and equipment manufacturers vowing to follow suit and adopt NACS access for charger customers. Here are a few:

  • ABB
  • Blink Charging
  • Chargepoint
  • EVgo
  • FLO
  • Freewire
  • Tritium
  • Wallbox

With a slew of major players in the EV and charging world now onboard, Tesla’s Supercharger network is growing in size and value, and could be worth as much as $100 billion. Meanwhile, the American automaker continues to open up access to its chargers to non-Tesla EVs in new markets like China.

Looking ahead, CCS will remain a standard in North America for the time being, but it appears to be on borrowed time as three of the world’s largest automakers are transitioning to NACS. Some other OEMS are sure to dig their heels in and stick with CCS, but we may one day see the plug out to pasture next to CHAdeMO as yet another stepping stone to smaller, faster, and more universal charging standards.

NACS Charging FAQ

What does NACS stand for?

North American Charging Standard.

Who created NACS?

Tesla introduced NACS charging in 2012 with the launch of its Model S sedan and its own proprietary Supercharger network.

Is NACS available in Europe?

No. At least not yet. The charging standard is just beginning to be hailed as the new method of charging in North America only. Europe still primarily uses the CCS Type 2 standard. That could always change though, but it will take time.

What automakers have committed to NACS so far?

There are more and more each day, but major ones to note are Tesla (obviously), Ford, GM, and Aptera. Other legacy automakers like Stellantis have not ruled out switching to NACS, but are not ready to commit just yet.

What are the advantages of the NACS plug?

The NACS plug is smaller and more compact, and offers more seamless access to Tesla’s growing Supercharger Network – arguably the most reliable and established on the planet.

Will older EV models be able to use Tesla chargers?

Yes. Tesla is in the process of opening its charger network up to most all EVs, whether they have NACS capabilities or not. Older or CCS-type EVs will be able to connect using Tesla’s Magic Dock adapter.

It’s time to start recommending some Tesla Powerwall alternatives [update]

It's time to start recommending some Tesla Powerwall alternatives [update]

For years, Tesla Powerwall has been the go-to recommendation for “normals” looking for a painless, low-effort experience from their first home solar and battery backup solutions. Its CEO’s recent involvement in controversial politics, however, means that people are now distancing themselves from the once-trailblazing company.

It begs the question: what other home solar battery solutions are there?

UPDATE 26JUL2025: added more options, put everything in alphabetical order.

Electricians and contractors often praise the sleek, energy-dense Tesla Powerwall, for good reasons. But the Powerwall isn’t the only top-shelf home battery on the market, but long wait times, Elon’s antics, and the proliferation of really good integrated alternatives from legacy EV brands might have you shopping for Tesla alternatives already. If that’s you, the next logical step is to re-think the brand’s solar battery offerings as well – here are some of the best options out there.

As I was putting this list together, I realized there were plenty of ways for me to present this information. “Best batteries ..?” Too opinion-based. “Cheapest batteries ..?” Too much research and a quick descent into Temu-grade nonsense. In the end, I went with the same solution I’ve been using on my 0% EV financing lists: alphabetical order, by brand. Enjoy!

Bluetti EP800 + B500

If you’re in a smaller space or renting and can’t (or don’t want to) add a hardwired battery solution to your home, Bluetti’s EP800 + B500 modular system is a sweet “middle ground” option that combines the Bluetti EP800 off-grid inverter and the company’s B500 battery packs in a floor-standing unit that can be used without a solar roof but also plays well with most rooftop PV options.

The basic EP800 + B500 package offers about 9.9 kWh of capacity for under $9,000 as I type this, and the system can scale up to nearly 20 kWh by adding more B500 packs. The system puts out 7.6 kW of power – more than enough, in other words, to keep some lights on and your fridge and foods (and meds) cold.

What’s more, it works great with Bluetti’s AC300 or AC500 gear if you want an option that’s a bit more portable if you move a lot or plan on moving soon.

EG4 14.3 kWh PowerPro

Two of the home solar installers I talked to in preparing this post mentioned the EG4 14.3kWh batteries, and its specs (on paper, at least) compare nicely with the Powerwall 3.

Battery Usable capacity (kWh) Continuous power output (kW) Roundtrip efficiency Average price per kWh* Coupling
Tesla Powerwall 3 13.5 11.5 97.5% $926 DC or AC
EG4 14.3kWh PowerPro 11.44 10.24 99% $786 DC

“The EG4 PowerPro solar battery from EG4 Electronics is the strongest alternative to the Tesla Powerwall,” writes Kristina Zagame, from the home solar experts at EnergySage. “(The EG4) has a similar capacity, meaning it’ll last a similar amount of time, and a slightly lower power output, which means it won’t be able to power quite as many devices at the same time. And, based on quotes through EnergySage, EG4 batteries tend to be a bit more affordable compared to Tesla.”

Enphase IQ Battery 10

If you’re looking for a one-brand solution for EV charging and whole-home battery backup but don’t want to be “locked in” to GM or Tesla’s ecosystem, Enphase offers a full line of Made-in-the-USA solutions that could be right for you.

“Energy systems developer Enphase Energy is providing an even more holistic approach to managing home power usage with the introduction of new EV charger technology called the IQ line,” wrote Scooter doll, when the brand first introduced its EV charging solutions back in 2023. “The Enphase IQ is Wi-Fi enabled and integrates seamlessly into a customer’s existing home system that can be controlled with your phone.”

Franklin WH aPower 2

If you love the sleek, minimalistic styling of the Tesla Powerwall 3 but still prefer to spend your money elsewhere, the Franklin WH aPower 2 offers similarly sleek styling and beats the Tesla offering on usable energy storage capacity by 1.5 kWh. That’s nearly a full day of keeping a modern refrigerator running.

The Franklin is also designed to be easily retrofit into an existing solar system, but it loses out to the Powerwall on price per kWh, at $1,176 (vs. $926 for the Tesla unit).

GM Energy Home System

Arguably the most fully integrated EV + battery backup + solar option out there outside of Tesla, the GM Energy Home System promises to do everything a conventional home solar battery does, plus work seamlessly with your GM EV to provide even more flexibility – whether that means using the electric fuel stored in your EV to hold out that much longer in an emergency, or using the energy stored in your home’s solar battery to power an escape in your EV is up to you.

GM Energy and GM’s car dealers list Qmerit as their installation partner, and they’re great, but if you “already have a guy,” you can order the Home System directly from GM Energy’s website for $12,700 (as I type this).

The GM Energy Home System system includes:

  • GM Energy PowerBank
  • GM Energy PowerShift Charger
  • GM Energy Home Hub & Inverter

StorEn vanadium flow BESS


StorEn Vanadium Flow Batteries

If lithium-ion’s ten-year cycle life or overhyped fire risk makes you nervous, StorEn Technologies is developing a consumer-focused battery solution based on vanadium flow chemistry. Their system promises to last 25 years or more with no capacity loss, so you can charge and drain the battery fully each day and without stressing about wear … but there are a couple of downsides.

First, they’re not yet available to the general public – only to StorEn’s early investors in (what I understand to be) a sort of quasi-Kickstarter deal.

Second, the StorEn batteries are significantly bulkier than a Powerwall. That said, if you’ve got the room and you’re old enough to realize that 25 years isn’t actually a super long time, the StorEn solution might to be a super compelling, nearly maintenance-free setup that might outlast both your solar panels and the roof they’re mounted on.


VillaGrid+ battery; via Villara.

So, remember how I started this off saying that I wouldn’t turn this into a “best batteries” post? That’s partly driven by the fact that I’m neither an electrician, a chemical engineer, or someone who’s researched thousands of end-user experience surveys to come up with whatever metrics I’d need to confidently and correctly call one battery “the best.”

Our friends and solar industry experts at EnergySage, though? They’ve got all three of those things on staff, and they really, really like the Villara VillaGrid+.

“The Villara VillaGrid+ stands out as the best battery on the market, scoring highest in EnergySage’s rigorous Equipment Rating System, explains EnergySage’s Kristina Zagame. “That said, (the Villara VillaGrid+) is not necessarily the best Tesla Powerwall alternative. It’s a very different (and much pricier) battery.”

What puts the VillaGrid+ on top? According to Zagame, it all comes down to the battery’s lithium-titanium-oxide, or LTO chemistry. “Unlike more traditional lithium-ion batteries, LTO has better recharge capabilities for longer life cycles, and doesn’t contain any carbon, which makes it extra safe. The only downside is you’ll definitely shell out more money upfront for the VillaGrid+.”

That extra money will also buy some additional peace of mind, as Villara backs its LTO batteries with a 20-year warranty compared to Tesla Powerwall and its (and just about everyone else’s) 10-year deal. I couldn’t find a price, but Villara’s other products, like VillaGrid 5.75 kWh battery, come in at nearly double Powerwall’s per kWh cost. Check out the specs, below, then let us know if you think the novel chemistry and additional warranty are worth it in the comments.

Battery Usable capacity (kWh) Continuous power output (kW) Roundtrip efficiency Average price per kWh* Coupling
Tesla Powerwall 3 13.5 11.5 97.5% $926 DC or AC
Villara VillaGrid+ 11.5 10 98.5% Get quote DC or AC

Vertical Aerospace completes first ever public airport-to-airport eVTOL flight

Air taxi startup Vertical Aerospace achieved a world’s first this week, completing the first flight between two airports through public airspace for an eVTOL at the Royal International Air Tattoo in Gloucestershire, England.

The Royal International Air Tattoo (RIAT) is the world’s largest military airshow, held every July and serving as a public showcase for the latest advancements in aviation technology. It’s fitting, then, that RIAT served as setting for the Vertical VX4 prototype’s first piloted public flight.

The eVTOL aircraft flew 17 miles from the company’s Flight Test Centre at Cotswold Airport to RAF Fairford, a Royal Air Force station used by the US Air Force. The Vertical VX4 reached speeds of 115 mph, and an altitude of 1800 ft, and also marked the first landing at a public location for an aircraft of this type.

The Vertical Aerospace entry was the only battery-electric aircraft present at RIAT 2025, and the flight served as a demonstration of the company’s broader strategy to unlock new hybrid-electric applications for defense, logistics, and special/close support missions where the eVTOL’s (relatively) quiet operations could give it a tactical advantage.

“RIAT is a global stage for the most advanced, mission-ready aerospace technology, and we’re proud to showcase how electric aviation will support the future of defense,” says Stuart Simpson, CEO of Vertical Aerospace. “Our hybrid-electric roadmap unlocks new capabilities for military operations, and Vertical’s RIAT presence reinforces our commitment to playing a meaningful role in the future of military and special mission aviation.”

Vertical’s VX4 debuted last year, with a 20% increase in the power-to-weight ratio that enables a top cruising speed of 150 mph and transports four passengers plus a pilot up to 100 miles on a single charge.

The inaugural VX4 flight was witnessed by several thousand UK aircraft enthusiasts, and showed how an eVTOL aircraft could integrate with real-world airport operations, building momentum toward more regular, certified deployment.

Electrek’s Take


Archer, BETA, EHang, Joby, XPeng – the list of eVTOL manufacturers seems to be as long as the list of new electric car brands that didn’t exist back when I first started working with EVs back in ::gulp:: the 1990s. The future of regional point-to-point air travel certainly seems to be vertical, and electric.

Honda takes a page from Tesla playbook, launches new insurance business

Say what you will about Elon Musk, but Tesla has changed the way that millions of people buy cars and, by extension, car insurance. Now, Honda is taking a page from Tesla’s successful playbook and launching its own in-house insurance business. Enter: Honda Insurance Solutions.

Honda Insurance Solutions is being launched as a fully licensed insurance agency serving the insurance needs of Acura and Honda customers, but it’s not stopping at competitive pricing and coverage options for Honda cars and motorcycles. Honda Insurance Solutions promises to go several steps beyond Tesla’s offering with coverage for trailers, RVs, homes, and even pets.

“Honda Insurance Solutions offers customers access to coverage through a brand they know and trust,” says Petar Vucurevic, President, American Honda Insurance Solutions, LLC and Senior Vice President, American Honda Finance Corporation. “Insurance is a key touchpoint in the vehicle ownership journey, and we aim to deliver a superior experience tailored to the unique needs of each customer, while promoting safer driving and increased peace of mind on the road.”

The company says the launch of its new insurance business is just part of Honda’s broader digital vehicle sales platform strategy, with future plans to integrate insurance offerings into new products.

Electrek’s Take

It’s important to note some of the key differences between Honda’s insurance offering and Tesla’s. Honda isn’t offering discounts, they’re not bundling insurance premiums into the vehicle financing, and they’re not building their insurance offerings into their dealerships’ checkout/F&I offices. Not yet, anyway.

What Honda is doing right now is deepening relationships with its existing customers and finding ways to make money on products it hasn’t sold them – whether that’s the Harley parked in the garage next to their Prologue or the garage itself.

It’s a smart play. And, once Honda figures out a way to cut franchise dealers out entirely and go to a direct sales model, it’ll look even smarter.
