Zürich Switzerland-based Juice Technology AG aims to simplify home and travel charging with the Juice Booster 2, a level 1 and 2 portable charger that is tough as nails. We use it on our own EVs to find out how it fares.

As veterans, we often forget, but new EV owners don’t realize just how pitiful the stock charger is with a new electric car. Many manufacturers include a charger in the trunk that can charge with a regular 120v outlet. An overnight charge will add about 30-40 miles to the average EV, which isn’t enough for much more than daily tasks.

To get more use from their EV, The committed owner is obliged to install a dedicated 240v circuit in their home, and install a faster level 2 system which can charge most cars overnight. After power gets to the wall, an EVSE (Electric Vehicle Service Equipment) is affixed to the home. Normally these are plastic boxes with a simple display that imitate larger pedestals at public charging stations. 

Why the Juice Booster 2?

The Juice Booster 2 is an ultra durable home EVSE, which can also be fitted with native connector types and taken on the road. The unit itself will determine all the proper input and output automatically, and charge the car so long as the power source plug (or adapter) is plugged in. On the face of the enclosure is a simple binary indicator for Faults, Current, and Mode. Changing mode will changes the display from a light to dark mode, in case the persistent blinking charging indicator bothers you (although, many EVs have their own light display that can’t be turned off).

The current offering for the USA market features a J1772 plug, which is standard for most makes of electric vehicles, at least for now. Going into the power source, Juice has a variety of connectors available, including TT-30, 6-50, 6-15, 6-20, and 5-20.

Juice Booster 2 at home

As a home unit, the Juice Booster 2 can charge up to 22kw with the right power source. At this rate, most any EV will be charged overnight. This is a much faster top current compared to many competitors, which cap at 12kw. Will your home outlet provide that kind of power, and is that the speed at which you want to charge your car every day? Probably not. Thanks to the current selector on the Juice Booster 2, the charger can be tailored to provide the right amount of power without charging the car too fast over the lifetime of the battery.

Scuffed up the rubber cup, but oh well.

Juice Booster durability

Plastic, wall mounted home EVSE units are not durable. They sit cozy on the wall, and that’s their lot in life. The Juice Booster 2 is made to withstand the elements, and immense crushing weight. The unit is IP67 rated for dust and water resistance, and is tough enough to be run over with a 5,000 lb electric car. I did it twice myself.

While this kind of durability seems like a parlor trick, it’s super practical considering that these units are sometimes left straddling the garage, and prominently placed in the pathways of vehicle tires. Not having to worry about squashing a charger solves one of the first concerns of new EV owners.

Nema 5-10 Connector (Included)

Juice Booster 2 abroad

Traveling with an EV is a new experience for many, one that requires less and less planning as time goes on. The Juice Booster 2 is sold as a travel charger that can be plugged into a variety of sources, using their native connector, or 3rd party adapters. This feature seems to have a lot more value in other markets, like Europe, where regularly crossing borders result in different plugs and voltage levels that require adaptation.

Home Outlet/Nema 5-15 Plug (Included)

In the land of stars and stripes, this feature is less useful. Traveling on the road, (and not using public chargers) the only outlet of regularity is the common 120v home outlet. Plugging into a 240v dryer or oven outlet is certainly possible, but how often do we need this charger, and also feel comfortable asking our house hosts to use them?

With L6-30 Adapter (Not Included)

Juice Booster 2 use case

I’m going to imagine that many USA customers won’t get much value from the travel application of the Juice Booster 2, but here is an illustration to show how it can be great.

Every couple months or so, we pack up the kids for a trip to the grandparent’s house, which happens to be in the country. Their small town doesn’t have a public charger nearby, and likely won’t for some time. Our EV can make a round trip from the closest public charger, but we like to charge after arriving, especially in the winter.

Juice Booster plugged in

Grandpa has been trying for years to justify his welding equipment, which required a specialty 240v outlet in the garage. With the use of a simple adapter, we were able to plug in the Juice Booster 2, and solve three issues: #1, charge up the car, #2, make Grandma feel like we will come over more often, and #3, justify Grandpa’s largely unnecessary expenditure (he uses it like once every five years).

After running it over, twice.
(Included wall mount)

Electrek’s Take

After using the Juice Booster 2 for some time, I think it’s a great option for someone getting their first home EVSE. The design is impressively durable, and I really like the source connector, as it locks into place and confirms a great purchase on the plug. The ease of mind for durability and whether resistance is top notch, especially if a car has to be charged without a garage or cover.

If you have circumstances anything like mine, then the Juice Booster 2 could be a surprisingly good fit for your car. On the other hand, if you already have a home EVSE, and a 120v trickle charger in the trunk, then you’re pretty much set.

State treasurers ask Tesla’s board (TSLA) to do its job and Rein in Elon Musk

State treasurers ask Tesla's board (TSLA) to do its job and Rein in Elon Musk

Tesla (TSLA) board members have received a wake-up call letter from eight state treasurers, asking them to fulfill their duties and supervise the company’s CEO, Elon Musk.

Will they ignore this warning as well?

There have been concerns about Tesla’s board sleeping at the wheel for a while now.

Their job is to oversee Tesla’s management for the benefit of shareholders, but Tesla’s stock is down almost 40% this year while the CEO is splitting his time between 6 different companies and projects while alienating most of Tesla’s consumer base.

Yet, the board hasn’t said a word about it.

The situation lends weight to the argument that the board is entirely under Musk’s control, which is the main point of contention in Tesla’s $55 billion CEO compensation case.

Now, eight state treasurers have joined forces to raise their concerns with the board. They wrote in a letter addressed to Robyn Denholm, chair of Tesla’s board:

We are increasingly concerned that Tesla’s recent performance signals deeper governance and leadership challenges that, if left unaddressed, could have serious consequences for the company and its stakeholders. In the first quarter of 2025 alone, Tesla’s stock declined by 36%. The company missed delivery targets, recalled a substantial number of vehicles, and experienced a surge in trade-ins for competing brands. Meanwhile, CEO Elon Musk continues to divide his attention across multiple companies and a high-profile advisory role within the federal government. These external commitments raise serious questions about whether Tesla’s leadership is fully engaged in addressing the company’s core challenges.

In the letter, the treasurers remind Tesla’s board of its duty “to provide strong oversight, uphold fiduciary standards, and ensure that the company’s leadership is aligned with the long-term best interests of the company.”

They are directly asking the board three questions:

  1. How is the Board ensuring that Mr. Musk and Tesla’s leadership team are devoting adequate time and focus to resolving recent performance issues and guiding the company’s future direction?
  2. In light of the company’s underperformance, how is the Board evaluating whether executive compensation remains aligned with shareholder value and corporate accountability?
  3. How does the Board plan to communicate its strategy for navigating this period of uncertainty and restoring investor and public confidence in Tesla’s leadership?

Tesla is going to release its Q1 2025 financial results today, hold its earnings conference call, and have a “live company update.’ Maybe some of these questions will be answered.

Here’s the letter in full:

2025-04-17 Letter to Tesla Board Chair

April 17, 2025

Robyn Denholm

Chair of the Board

Tesla, Inc.

1 Tesla Road

Austin, TX 78725

Dear Chair Denholm,

We are entrusted with promoting the long-term economic health and financial stability of our states and the people we serve. Tesla, Inc. is not just one of the world’s most valuable companies—it is a major player in the clean energy economy and a leading force in emerging technologies such as robotics and autonomous driving. The company’s success or setbacks have significant implications for workers, regional industries, and innovation ecosystems in our states.

We are increasingly concerned that Tesla’s recent performance signals deeper governance and leadership challenges that, if left unaddressed, could have serious consequences for the company and its stakeholders. In the first quarter of 2025 alone, Tesla’s stock declined by 36%. The company missed delivery targets, recalled a substantial number of vehicles, and experienced a surge in trade-ins for competing brands. Meanwhile, CEO Elon Musk continues to divide his attention across multiple companies and a high-profile advisory role within the federal government. These external commitments raise serious questions about whether Tesla’s leadership is fully engaged in addressing the company’s core challenges.

We regularly interact with stakeholders across our states, including institutional investors, industry leaders, workers, and small businesses. We are hearing increasing concern about Tesla’s direction, not only from financial professionals but from those who have looked to Tesla as a leader in clean energy innovation and American industrial renewal. If Tesla falters, the effects won’t be confined to shareholders—they will ripple through regional economies, workforce pipelines, and public confidence in the energy transition.

At a moment when American industrial leadership is facing stiff global competition, it is essential that companies like Tesla are governed with focus, discipline, and clarity of mission. The Board’s role is especially critical now—to provide strong oversight, uphold fiduciary standards, and ensure that the company’s leadership is aligned with the long-term best interests of the company. Public officials like us do not take the step of raising these concerns lightly except when the obvious risks demand it.

We believe the Tesla Board has a responsibility to act decisively to ensure the company returns to a stable and focused trajectory.

We respectfully request the Board provide clarity on the following:

  1. How is the Board ensuring that Mr. Musk and Tesla’s leadership team are devoting adequate time and focus to resolving recent performance issues and guiding the company’s future direction?
  2. In light of the company’s underperformance, how is the Board evaluating whether executive compensation remains aligned with shareholder value and corporate accountability?
  3. How does the Board plan to communicate its strategy for navigating this period of uncertainty and restoring investor and public confidence in Tesla’s leadership?

Finally, we strongly believe Tesla’s Board would benefit from engaging with public sector stakeholders who share an interest in the company’s long-term value and societal impact. We welcome the opportunity to speak further about these concerns and discuss how the Board can take swift and transparent action to restore investor confidence and public trust in Tesla’s leadership and the company’s future.

We welcome a response and the opportunity for continued dialogue.

Signed,

Mike Pellicciotti, Washington State Treasurer
Deborah B. Goldberg, Massachusetts State Treasurer and Receiver-General
Michael W. Frerichs, Illinois State Treasurer
Erick Russell, Connecticut Treasurer
Laura M. Montoya, New Mexico State Treasurer
David L. Young, Colorado State Treasurer
Mike Pieciak, Vermont State Treasurer
Malia M. Cohen, California State Controller

Electrek’s Take

Tesla is a $700 billion publicly traded company that is run like a family business by Musk, who owns just 13% of the float.

The board, which was so handsomely rewarded that it had to return almost $1 billion worth of compensation as part of a shareholder lawsuit, is letting Musk do whatever he wants without any objection.

It’s clear that they have a quid pro quo with Musk, whereby they receive compensation at a rate several times higher than any other similarly sized company in exchange for allowing Musk to run Tesla as if it were his private company.

While I am glad they sent this letter, I doubt that a group of state treasurers will convince Tesla’s board to do anything.

At this point, they are either completely fine with Musk destroying Tesla or they believe his claims about self-driving technology.

Chevron sees no signs that U.S. is close to a recession, CEO says

Chevron sees no signs that U.S. is close to a recession, CEO says

Chevron CEO Mike Wirth: No signs that we're in or close to a recession at this point

Chevron is not seeing signs that the U.S. is close to a recession even as President Donald Trump’s tariffs weigh on expectations for oil demand, CEO Mike Wirth said Tuesday.

“There’s no signs that we see at this point that we are in or close to a recession,” Wirth told CNBC’s “Squawk Box.” “There are signs that growth may be slowing and we have to always be prepared for that.”

The International Monetary Fund on Monday cut its growth outlook for the U.S. this year to 1.8%, down from 2.7% previously.

The oil market is expecting reduced demand as a consequence of Trump’s tariffs and the decision by OPEC+ increase production faster than expected, Wirth said. Chevron isn’t changing its capital spending plans in response to drop in prices, the CEO said.

U.S. crude oil prices have fallen about 11% since Trump announced his tariffs on April 2. West Texas Intermediate was last up about 72 cents at $63.80 per barrel. OPEC and the International Energy Agency have cut their demand outlooks for this year.

Wirth said U.S. onshore oil production in patches like the Permian Basin is likely to pull back if prices hit $60 per barrel. Offshore production likely won’t be affected, he said.

“That’s an area where if we were to be at a $60 price or even lower you’re likely to see activity pull back in this sector and you’ll see the production response over a few months,” Wirth said. “That’s what we should watch, not so much the deep water activity.”

Chevron is not expecting a major direct impact on its business from Trump’s tariffs as energy has largely been exempt from the levies, Wirth said.

“The effects that we feel are likely to be more the macroeconomic effects as they flow through the economy,” Wirth said. “The bigger issues would be what would it mean for growth, and global trade and how does that evolve.”

Executives at oil and gas companies were scathing in their criticism of Trump’s tariffs in an anonymous March survey by the Federal Reserve Bank of Dallas, warning that steel tariffs were raising their costs and low prices could impact their activity.

Billionaire battle: Bezos’ $25K Slate EV breaks cover ahead of Tesla earnings call

Billionaire battle: Bezos' K Slate EV breaks cover ahead of Tesla earnings call

Little is known about super-secretive EV startup Slate, but the fledgling brand is rumored to be backed by Jeff Bezos and determined to shake up the existing electric order with an affordable lineup of compact SUVs and pickups with that golden $25,000 price tag.

Now, at least, we know what it’s gonna look like. The battle of the billionaires is on!

Redditor jonjopop over at the spotted subreddit spotted what looks like an early prototype of an unbranded SUV with bizarre “CryShare” wrap. CryShare, as a concept, seems to combine the functionality of a ride sharing app like Uber or Lyft with the familiar (to parent, anyway) idea that small babies will often sleep better in a moving car than in their own cribs … but that’s not what’s important here.

Instead, focus on the vehicle itself – parked on Abbot Kinney Boulevard in Los Angeles without explanation or fanfare, this is our best look yet at the kind of vehicle(s) Slate is likely to reveal in the coming days.

Stumbled upon the Bezosmobile [Slate Automotive…idk?] being revealed with an absolutely bizarre marketing campaign
byu/jonjopop inspotted

Other local automotive journalists caught wind of the public unveiling, too – and our friends at The Autopian (Hi, Matt!) sent their own David Tracy out on the streets of LA to check it out. Tracy took the following video and posted it to Instagram.

The Slate breaking cover and causing buzz just ahead of what’s sure to be a painful Q1 earnings call for Tesla is a masterstroke of marketing – especially as doubts surrounding the viability of a “less expensive” Tesla Model Y or Model 3 continue to mount amid the uncertainty of Trump’s tariffs and declining sales of the brand’s more profitable models both at home and abroad.

As with so much involving Slate, however, there is nothing here written in stone – or even cast in cheese. Nothing has been announced, nothing is promised, and for all we know this might have more to do with the affordable Rivian brand launch, a new BYD, or be a viral marketing bit from some local Art Center design student in (relatively) nearby Pasadena. In fact, about the only thing I think we can say about Bezos (?) new Slate project with confidence today is this: Elon could probably use that drink.
