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.

Several Tesla vehicles were set on fire at Tesla service center in Las Vegas. More Tesla vehicles were also set on fire in Kansas, arson is also suspected in this case, but it’s not confirmed.
Tesla is facing protests at stores across the US over masses trying to negatively affect Elon Musk who many believes is establishing himself as a oligarch in the US.
On top of the peaceful legal protests, more extremist groups are also attacking Tesla with vandalism.
Protests are not slowing down with over 100 planned for the next 2 weeks and unfortunately, the vandalism attacks on Tesla also don’t appear to be slowing down.
Just last night, there were two instances.
The first one was at Tesla’s service center in Las Vegas were several vehicles were reportedly set on fire (pictured above).
The Las Vegas Metropolitan Police said that they were told that an individual set the vehicles on fire, but they are still investigating:
“LVMPD Communications received information that an individual had set several vehicles on fire in the parking lot and caused damage to the property,”
The FBI is reportedly being involved.
President Trump said last week that he wants to classify vandalism against Tesla as “domestic terrorism.” We previously reported that the FBI has already gotten involved in several instances of vandalism at Tesla stores.
In a separate instance in Kansas City last night, two Tesla Cybertrucks burned down at the local Tesla store.
A KCPD officer spotted the fire and tried to extinguish it himself but couldn’t. Firefighters had to come and the fire spread to a second Cybertruck in the meantime.
The KCPD Bomb and Arson unit is investigating the cause – therefore, arson is also suspected but not confirmed yet.
Tesla vehicles have at times caught on fire on their own – although it’s a rare occurrence.
Electrek’s Take
As we have often mentioned in the last few weeks, we sympathize with the people peacefully protesting and boycotting Tesla, but we condemn any violence, including vandalism.
The protests and boycotts are much more efficient in affecting Tesla than any form of violence, including setting cars on fire. Tesla will just collect the insurance anyway.
Everyone getting involved in this is actually eroding the credibility of the “Tesla Takedown” movement.

Rivian is plowing ahead with its new midsize R2 electric SUV. As it gears up for production, Rivian’s CEO, RJ Scaringe, gave us a sneak peek at the R2 body being built with production dies.
First look at the Rivian R2 body with production dies
Starting at $45,000, the R2 will be about half the cost of Rivian’s current R1S ($77,700) and R1T ($71,700). Despite a smaller size, the company promises it will still have that “Rivian essence” that has helped get the EV maker to where it is today.
Rivian’s CFO, Claire McDonough, said the team was “working around the clock” earlier this month to prepare its Normal, IL facility for R2 production.
McDonough confirmed that the sourcing for R2 was about 95% complete, and the start of production was still scheduled for the first half of 2026.

In the meantime, Scaringe is giving us a closer look at the R2 as it goes through development. Earlier this month, he posted a picture of the R2’s highly efficient Maximum drive unit.
The new unit uses continuous winding in the stator to reduce the total welds per stator assembly from 264 to just 24. With an integrated rotor shaft and gear, Maximum uses just two bearings, down from four on its Enduro drive unit.
As Rivian moves closer to production, we’re getting an up-close look at the R2 body being built. Rivian’s CEO shared a picture on X showing the R2 body, now built with production dies.
Although Rivian will begin building R2 models in Normal, it will significantly ramp up production at its new plant in Georgia. McDonough said the GA facility is still on track to come online in 2028.

Once fully up and running, it’s expected to have up to 400,000 annual vehicle production capacity. To put that into perspective, Rivian built just shy of 50,000 EVs last year.
After scaling production, Rivian will launch the R2 in Europe as it takes the brand overseas. The company promises that R2 is just the start. Next up, Rivian will launch the smaller R3 crossover and R3X, a tri-motor electric hot hatch.
