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.

Tesla CEO Elon Musk threw shade at Waymo for having “rookie numbers” amid Tesla’s own disappointing autonomous-driving performance, raising the question: Is Elon Musk delusional or simply lying about Tesla’s Full Self-Driving?
Every year since 2018, Musk has alternately claimed that Tesla would solve self-driving “by the end of the year” or “next year.”
It never happened.
Tesla claimed a sort of victory this year with the launch of its “Robotaxi” service in Austin, Texas, but even that has been misleading since the service only operates a few vehicles in a geofenced area, something Musk has criticized Waymo for in the past, and unlike Waymo, Tesla has in-car supervisors with a finger on a killswitch to stop the vehicle in case of a potential accident.
Now, Musk called Waymo’s 2,500 fully autonomous vehicles currently in operation “rookie numbers”:
To put the comment in perspective, Tesla is believed to have about ~30 “Robotaxis” in its Austin fleet. In addition, Tesla claims to be operating “robotaxis” in the Bay Area with just over 100 cars, but it is officially considered a ride-hailing service because drivers are in the driver’s seat, and Tesla hasn’t even applied for an autonomous driving permit in California.
Tesla has also been pushing increasingly more misleading claims about its “Full Self-Driving” system being safer than humans.”
In the last few weeks, Tesla has repeatedly shared this misleading data as “proof” that its system is safer than humans:
This dataset is based on Tesla’s quarterly “Autopilot safety” report, which is known to be misleading.
There are three major problems with these reports:
Methodology is self‑reported. Tesla counts only crashes that trigger an airbag or restraint; minor bumps are excluded, and raw crash counts or VMT are not disclosed.
Road type bias. Autopilot is mainly used on limited‑access highways—already the safest roads—while the federal baseline blends all road classes. Meaning there are more crashes per mile on city streets than highways.
Driver mix & fleet age. Tesla drivers skew newer‑vehicle, higher‑income, and tech‑enthusiast; these demographics typically crash less.
With the new chart on the right above, Tesla appears to have separated Autopilot and FSD mileage, which gives us a little more data, but it still has all the same problems listed above, except the road-type bias is less pronounced, since FSD is also used on city streets.
However, many FSD drivers choose not to engage FSD in potentially dangerous or more difficult situations, especially in inclement weather, which contributes to many crashes – crashes that are counted in the human driver data Tesla is comparing itself against.
Lastly, it is unfair to say that the data proves FSD is safer than human drivers, as even with the flawed data, Tesla should claim that FSD with human supervision is safer than human drivers. It’s not FSD versus humans, it’s FSD plus humans versus humans.
It leads us to this.
With Tesla and Musk being undoubtedly wrong and misleading about the performance and the very nature of its current autonomous driving offering, I wanted to know your opinion about the situation through this poll:
Electrek’s Take
Personally, I think it’s a little of both.
I think he sometimes really believes Tesla is on the verge of solving autonomy, but at the same time, he is perfectly willing to cross the line and mislead people into thinking Tesla is further ahead than it actually is.
For example, I believe I can explain this comment about Waymo having “rookie numbers” despite the Alphabet company having about 10x more “robotaxis” than Tesla – even with Tesla’s very loose definition of a robotaxi.
Based on job listings across the US and his recent ridiculous comment that Tesla will magically cover half of the US population with robotaxis by the end of the year, I think Tesla is hiring thousands of drivers. Soon, it will put them in Model Ys with ‘Robotaxi’ stickers on them and have them drive on FSD and give rides in the Robotaxi app in several US cities.
Musk will claim that Tesla’s Robotaxi is now bigger than Waymo, even though it will basically be the equivalent of Uber drivers in Tesla cars with FSD, which is already the case. Just this week, I took an Uber from the Montreal airport, and it was in a Model Y with FSD. Has Tesla launched ‘Robotaxi’ in Montreal?
It’s either that or he counts consumer vehicles with FSD, which is even dumber.
In short, he is delusional, and when he realizes that he was wrong, he is willing to lie to cover things up.

Solar and wind are growing fast enough to meet all new electricity demand worldwide for the first three quarters of 2025, according to new data from energy think tank Ember. The group now expects fossil power to stay flat for the full year, marking the first time since the pandemic that fossil generation won’t increase.
Solar and wind aren’t just expanding; they’re outpacing global electricity demand itself. Solar generation jumped 498 TWh (+31%) compared to the same period last year, already topping all the solar power produced in 2024. Wind added another 137 TWh (+7.6%). Together, they supplied 635 TWh of new clean electricity, beating out the 603 TWh rise in global demand (+2.7%).
That lifted solar and wind to 17.6% of global electricity in the first three quarters of the year, up from 15.2% year-over-year. That brought the total share of renewables in global electricity – solar, wind, hydro, bioenergy, and geothermal – to 43%. Fossil fuels slid to 57.1%, down from 58.7%.
Renewables are beating coal
For the first time in 2025, renewables collectively generated more electricity than coal. And fossil generation as a whole has stalled. Fossil output slipped slightly by 0.1% (-17 TWh) through the end of Q3. Ember expects no fossil-fuel growth for the full year, driven by clean power growth outpacing demand.

China and India are partly driving that shift. In China, fossil generation fell 52 TWh (-1.1%) as clean energy met all new demand, resulting from a structural change in its power system. India saw fossil generation drop 34 TWh (-3.3%), thanks to record solar and wind growth and milder weather.
Solar is leading the charge
Solar is doing the heavy lifting. It’s now the single biggest driver of change in the global power sector, with growth more than three times larger than any other electricity source in the first three quarters of the year.
“Record solar power growth and stagnating fossil fuels in 2025 show how clean power has become the driving force in the power sector,” said Nicolas Fulghum, senior data analyst at Ember. “Historically a growth segment, fossil power now appears to be entering a period of stagnation and managed decline. China, the largest source of fossil growth, has turned a corner, signaling that reliance on fossil fuels to meet growing power demand is no longer required.”
Electricity demand rose 2.7% in the first three quarters of 2025, far slower than the 4.9% jump seen last year when extreme heatwaves pushed up cooling demand in China, India, and the US. This year’s milder weather helped take some pressure off the grid, making it easier for clean energy to close the gap.
A turning point for the global power system
For the first time outside of major crises such as the pandemic or the global financial crash, clean energy growth has not only kept up with demand but surpassed it. The next big question: can solar, wind, and the rest of the clean power sector keep up this pace consistently? If they can, 2025 may be remembered as the year global fossil generation plateaued.

Genesis is taking luxury to the next level with its new flagship SUV. The GV90 is shaping up to be the brand’s most lavish vehicle yet, offering ultra-premium features like coach doors.
Genesis GV90 caught with coach doors in real life
After unveiling the Neolun Concept at the New York Auto Show last March, Genesis said it was a preview of its first full-size SUV.
The “ultra-luxe, state-of-the-art SUV,” as Genesis describes it, will be the brand’s largest and most luxurious vehicle yet, slotted above the GV80.
It wasn’t the stunning design or the over-the-top interior that caught most people’s attention, but the B-pillarless coach doors.

Although we were worried that some of the ultra-premium features, like the coach doors, wouldn’t make it to the production model, new spy photos reveal otherwise.
A GV90 prototype was spotted out in public with the coach doors wide open, giving us our closest look at the setup. The new spy photos, courtesy of SH Proshots (via TheKoreanCarBlog), show the hinged door system in action and offer a glimpse of the interior.
Earlier this year, Hyundai Motor filed several patent applications with the United States Patent and Trademark Office, detailing new door latching devices.
Two patents, titled “Cinching Device For Door Latches in Vehicle” and “Door Latch Device for Vehicles,” offer a better idea of how the Genesis GV90’s coach doors will work.
Genesis has previously said that B-pillarless coach doors are now a reality in production vehicles. It looks like the GV90 will be the first to debut it.
Yes, the Genesis GV90 will be available with coach doors, but it likely won’t be standard on all trims. It could be a premium feature reserved for higher-priced variants. The GV90 has been spotted out in public several times now with a traditional door design. We’ve also caught a glimpse of other premium features it will offer, like adaptive air suspension.

Genesis has yet to reveal prices or final specs. We could see the GV90 debut by the end of the year, with sales expected to start in mid-2026.
One thing is for sure: The Genesis GV90 won’t be cheap. It’s expected to start around $100,000, but higher trims could cost upwards of $120,000.

Earlier this week, a production version of the GV90 was caught for the first time driving in South Korea. It was still covered in camouflage, but from what’s shown, it looks nearly identical to the Neolun concept.
Reports suggest the flagship SUV could debut on Hyundai’s new eM platform. Hyundai claims the platform will deliver a 50% improvement in driving range per charge compared to its current EVs. It’s also expected to offer Level 3 autonomous driving and other advanced driver assist capabilities.
The flagship electric SUV will serve as a tech beacon, showcasing Hyundai’s latest tech and software. It’s expected to feature a massive 24″ curved infotainment as part of a digital cockpit design.
Genesis is also launching its first hybrid, the GV80, next year, and an extended-range electric vehicle (EREV) in late 2026 or early 2027. The luxury brand will also introduce a new off-road SUV as it expands into new segments.
