Ecoflow announced the Delta Ultra today at CES, its monster 6kWh home LFP battery pack on wheels. Its 240V/30A= 7.2kW output can back up a home the way a whole home generator or Tesla Powerwall can. However, this thing has wheels and can be loaded into a vehicle to be transported to a campsite or a remote location. EcoFlow provided us with one last month and we’ve taken it to an off-grid tiny home which it kept powered, even in the cold of winter, for a whole weekend. Let’s have a deeper look…
This is the biggest battery pack I’ve ever reviewed by a long shot. I’ve tried tons of smaller battery packs (even e-bikes!) with 120V AC inverters that you can plug laptops and sometimes as much as refrigerators into for short periods of time. But the Ultra can back up the whole home. Until now, that was something reserved for Tesla Powerwall-grade equipment (which I have 2 sets) that comes via electricians or smelly, noisy gas generators.
The EcoFlow Delta Ultra spec sheet is super impressive for an off-the-shelf product:
6kWh of LFP power, 3500 cycles, safer for inside usage, 7.2kW peak output
Weight: Battery 116 lbs + 70 lbs inverter = 186 lbs or 85 kg with wheels
Wifi + Bluetooth enabled plus app for monitoring remotely. Even an optional 4G dongle
Outlets galore including a 240V 30A generator plug and 120V 30A RV plug
Whole spec sheet follows:
The EcoFlow Delta Pro works seamlessly with a 60A Smart Home Panel which was too small for my home to try out. This is integrated into the app allowing remote management of circuits and 0ms cutover time in the event of a power outage.
Tiny House power
With, 14kW of Solar, a 200A breaker box with Tesla Powerwalls at my home, The EcoFlow Delta Ultra didn’t make sense as an additional home backup. However, a friend of mine has been using a rotation of batteries to rent an off-grid tiny house as an AirBNB. But these smaller batteries aren’t able to heat the home with a 240V heat pump. He either has to use a gas generator to power the heat pump, rely on a small wood stove, or stop accepting guests when it starts getting cold in the fall.
The Delta Pro with its 240V output and 6kwh of storage would likely be enough to heat the home for a weekend as well as run lights and entertainment for the weekend. The heat pump is quite efficient and while it requires almost 1.5kW to start up and heat the home within about 20 minutes, it only requires about 300W to keep the 200-square-foot tiny home warm throughout the weekend.
In practice, the Ultra worked as advertised in 40-degree weather, keeping the home at about 65 degrees and powering small appliances and entertainment. However, the LFP batteries likely suffered a bit with the lower temperature, still allowing the home to operate for 48 hours but using more of the battery than anticipated by about 5-10%. This could be remedied by moving the battery inside the warmer house.
The Ultra is very quiet, only kicking the fans on at the outset when the heat pump was firing up as well as the tiny refrigerator and load went over 2000W. Under 2000W, the fans turn off and it is completely silent.
The Ultra has a variety of inputs including solar options which may make sense for this tiny house going forward, making it a true off-grid solution. At about 3kWh/day, we figure about 1kW of solar is needed or about 3 economical roof panels. Five panels or about 1.6kW will allow for a bigger buffer and enough to start doing things like electric induction cooking (bye propane), and e-bike charging.
For now, he charges it at home on a 120V outlet which takes about 5 hours from empty. He delivers it ahead of the customers on Friday full and picks it up with a little remaining charge on Sunday evening.
For those people who own off-grid cabins, this could be the perfect product to take with them. And while at home, it can function as whole home backup power.
Electric Vehicle charger?
You can Level 2 charge an EV with this at 7.2kW and add 6kW of battery in about an hour, adding as much as 25 miles of range (depending on the vehicle). You can even do the reverse and charge it on an EV charger(!):
Availability
EcoFlow DELTA Pro Ultra will be available starting today Jan. 9 on the EcoFlow website and Amazon.com. On the EcoFlow website, users can purchase DELTA Pro Ultra (inverter and battery) for $4999, and the Smart Home Panel 2 is available for purchase at $1599, or as a bundled package with DELTA Pro Ultra for $6399 until February 9. After that period, the prices are $5799 for DELTA Pro Ultra, $1899 for Smart Home Panel 2, and $7499 for the DELTA Pro Ultra bundle.
Electrek’s take
EcoFlow’s Delta Ultra is a new breed of 240V portable batteries that will enable a new level of off-grid comfort where it hasn’t existed before. This is great for off-grid cottages, RVs, tiny homes, camping, and other applications. Adding solar makes this a one-stop shop. The wheels make it easier to move the 180-lb product from place to place.
I’m super impressed with how it performed out of the box quietly and reliably over the past month. The screen is very intuitive and it feels like EcoFlow has thought about everything here.
While I didn’t have an opportunity to try it, the smart breaker box and the stacking capabilities of this battery mean it can work with any sized home as both a battery backup and an off-grid solution. I think there’s a big opportunity here to also charge the battery at low-cost hours and use the batteries to power the home during high-cost times. Stay tuned for more from EcoFlow.

Petter Winberg, Tesla crash safety architect, via LinkedIn
Tesla’s top crash safety architect, who helped the automaker achieve top safety scores for its entire car line-up, announced that he is leaving the automaker after 14 years.
We are talking about Petter Winberg, Tesla’s Principal Engineer for CAE crashing safety for the last decade.
After an extensive career at Volvo and SAAB, both car brands praised for their commitment to safety, Winberg joined Tesla in 2011 to work on the “crash safety development of Model S structure and side occupant restraints.”
At the time, Tesla was still working on the Model S, its first vehicle built entirely from the ground up, considering the original Roadster was based on the Lotus Elise.

CEO Elon Musk aimed for “Tesla vehicles to be the safest on the planet,” and Winberg took the challenge seriously.
He led the development of the vehicle body and chassis structure for Model 3 and Model Y, as well as the crash structure for Model S and Model X.
All of these vehicles have received top safety crash scores from independent testers worldwide – quickly elevating Tesla’s brand into a leader in passive safety.
Winberg and his team deserve a lot of the credit for this.
The engineer also led the design of crash readiness and the energy-absorbing capacity of Tesla’s latest “gigacasting” and structural battery pack designs, for which he obtained patents. Other automakers have since adopted similar designs.
For those less technical who want to understand how good and respected Winberg is at Tesla, he has been working for Tesla remotely in Sweden for the last five years. That’s impressive in itself, considering how much Musk hates remote work. He previously emailed Tesla management to tell them that only exceptional employees would be eligible for an exemption to work remotely, which he would approve himself.
After 14 years at Tesla, Winberg announced last week that he is leaving (via LinkedIn):
Having developed Model S, S-DM, X, 3, Y, Y-SP as well as future crash architectures, I have decided now is the time to move on. Thank you Tesla, keep crushing it! What an incredible team, I will miss you all.
He didn’t elaborate on his reasons for leaving the automaker or announce another venture.
Electrek’s Take
While Tesla has received much criticism for the dangers of its Autopilot and “Full Self-Driving” systems, I don’t think anyone can question that Tesla vehicles perform extremely well in terms of passive safety.
Independent testing has proven it time and time again.
Tesla has led the way in taking advantage of designing electric vehicles from the ground up. Its skateboard-like powertrain design and lack of engine in the front allow for a giant crumple zone to absorb the energy in case of a crash.
A big thank you to Petter Winberg for his designs and leadership in improving Tesla’s passive safety. He has undoubtedly made the automotive industry safer and saved lives. Congratulations.
As for his departure, it’s certainly a blow for Tesla. As we previously reported, the company has suffered a significant exodus of talent over the last year, with a big part of its leadership leaving during and after a wave of layoffs last year.
Many predict that Tesla could again initiate another wave of layoffs in the coming months as its sales are crumbling worldwide.

Its first vehicle, the SU7, is a smash hit. It now consistently delivers over 20,000 units a month, it has surpassed the Tesla Model 3, its closest competitor, and has a more than 30-week-long backlog of orders.

The vehicle achieves more range and is cheaper than Model 3 while having additional features.
Last month, Xiaomi launched a new top-of-the-line version of the SU7: the SU7 Ultra.
The headline is that the $72,800 (529,900 RMB) has a powertrain packing up 1,526 horsepower. That’s absolutely insane. Xiaomi quotes a 0 to 100 km/h (0 to 62 mph) acceleration in just 1.98 seconds.
While the SU7 is meant more as a Model 3 competitor, the SU7 Ultra actually competes with Tesla’s flagship Model S Plaid in terms of performance.
They organized a drag race between the SU7 Ultra and Model S Plaid. Here it is:
As you can see, the SU7 Ultra slipped at the start, which is not surprising considering how much power it outputs, but it still managed to catch up and beat the Model S Plaid.
At over 1,000 horsepower, many, myself included, thought that it was a bit mad to offer a vehicle like the Model S Plaid with such supercar power for a relatively cheap price – RMB 814,900 (approximately $112,000 USD) in China and just $95,000 in the US.
But now, Xiaomi shakes things up even more by offering 1,500 horses for just a little more than $70,000. It’s mad.
Now, I can hear your thoughts: “but it’s just good in a straight line drag race like other EVs.” Think again, the SU7 Ultra prototype claimed the title as the fastest four-door sedan at the famous Nurburgring race track in Germany.
Electrek’s Take
Damn, the Chinese are good. Xiaomi has come hard with the SU7, but the crazy thing is that it’s just one of several Chinese top-of-the-line EVs coming out. Nio has the ET7, BYD has the U7, and there are many more.
These vehicles are all impressive in their own rights.
It’s easy to understand why American automakers are so scared and lobbied the US government for 100% tariffs on them.

HOUSTON — The officials leading President Donald Trump’s energy agenda made clear to oil, gas and mining executives this week that they have an ally in Washington who intends to make it as easy as possible for them to drill in federal lands and waters.
Interior Secretary Doug Burgum told executives gathered for the world’s largest energy conference that the Trump administration does not view climate change as an existential threat. Energy Secretary Chris Wright said rising global temperatures are simply a byproduct of developing the country’s national resources to support economic growth and national security.
Burgum leads Trump’s recently established National Energy Dominance Council and Wright serves as his deputy on the interagency body tasked with boosting production. Burgum was effusive in his praise of the oil and gas industry during remarks delivered at CERAWeek by S&P Global conference.
“I’m going to share two words that I do not think that you have heard from a federal official in the Biden administration during the last four years. And those two words are thank you,” said Burgum, who previously served as governor of North Dakota, a state that produces 1.2 million barrels of oil per day.
Burgum leaned on his experience as software company executive to lay out his view of the interior department’s role. The department under his leadership views the companies developing resources on federal lands as “customers” who are contributing revenue to the nation’s “balance sheet,” Burgum said.
“If someone was sending me revenue, they weren’t the enemy. They were the customer,” Burgum said. The administration loves anyone who wants to harvest timber, mine for critical minerals, graze cattle, or produce oil and gas on federals, the interior secretary said.
Royalties sent from lease agreements on federal land will help the U.S. pay down its national debt and balance the budget, Burgum said. “You’re the customer,” the interior secretary told the executives.
The value of nation’s abundant natural resources far outweighs its $36 trillion in debt, Burgum said. If financial markets understood the value of America’s natural resources, the 10-year long-term interest rate would come down, Burgum claimed.
“The interest rates right now are one of the biggest expenses we have as a country,” Burgum said. “So one of the things that we have to do is unleash America’s balance sheet, and President Trump is helping us do that,” he said.
Burgum slammed the Biden administration’s focus on climate change as an “ideology.” He said the Trump administration views Iran acquiring a nuclear weapon and China winning the artificial intelligence race as the two existential threats facing the U.S. rather than global warming. Wright said Biden had a “myopic” and “quasi religious” belief in reducing emissions that hurt consumers.
Burgum and Wright dismissed policies that support a transition from fossil fuels to renewable energy, arguing that wind and solar won’t be able to meet rising energy demand in the coming years from artificial intelligence and re-industrialization.
“There is simply no physical way that wind, solar and batteries could replace the myriad uses of natural gas. I haven’t even mentioned oil or coal yet,” Wright said at the conference. Wright previously served as CEO of oilfield services company Liberty Energy and a board member at nuclear startup Oklo.
Oil execs see allies in Washington
Oil executives are enthusiastic about the change of administrations in Washington, returning the praise they received from Trump’s energy team during the week.
ConocoPhillips CEO Ryan Lance said Wright and Burgum “understand the business,” describing them as the best energy team the U.S. has seen in decades. TotalEnergies CEO Patrick Pouyanné said he was “impressed by the quality of our counterparts.” Chevron CEO Mike Wirth said the industry is “seeing some reality come back to the conversation.”
“For years, my message has been, we need a balanced conversation about affordability, reliability and the environment, and focusing only on climate leads us to ignore the first two,” Wright said.
The executives all referred to the Gulf of Mexico as the Gulf of America, following Trump’s executive order to rename the body of water. The president issued an order on his first day to repeal Biden’s ban on offshore drilling in 625 million acres of U.S. coastal waters.
BP CEO Murray Auchincloss briefly slipped before correcting himself when discussing how generative AI is helping with exploration: “We started doing this in the Gulf of Mexico, uh America, and we spread that to other nations as well.”
But Trump’s calls to “drill, baby, drill” are running up against market reality. The CEOs of Chevron and Conoco said U.S. oil production will likely plateau in the coming years after hitting new records under the Biden administration.
“Chasing growth for growth’s sake has not proven to be particularly successful for our industry,” Wirth said. “At some point, you’ve grown enough that you should start to move towards a plateau, and you should generate more free cash flow, rather than just more barrels.”
Lance sees U.S. oil production plateauing later this decade and then slowly declining.
“Maybe it’s time to go back to exploring the Gulf of America,” Pouyanné said. “The new administration is opening the Gulf. It has been slowed down after the Macondo drama,” he said, referring the Deepwater Horizon oil spill, the largest in the history of marine drilling operations.
U.S. oil producers are scheduled to meet with Trump next week, industry lobby group American Petroleum Institute said in statement.
