Features

  • 1.8 Hrs to Full Charge. EcoFlow's patented X-Stream AC fast charging lets you recharge DELTA Max in only 1.8 hours. Or even quicker if you combine any two charging methods, that's from an AC wall outlet, solar panels, or a Dual Fuel Generator.
  • 2-6kWh Expandable Capacity. DELTA Max's large 2kWh capacity keeps your home appliances running during a blackout. Expand up to 6kWh with Extra Batteries, keeping your home powered on in any emergency.
  • Power Heavy-duty Devices with 2400W Output. 2400W output to power up to 15 devices at once. Power 3400W appliances with X-Boost on. That means during a power outage or blackout, you can continue to power your fridge, microwave, dryer, and more. Ideal power generator for backup power.
  • Solar Charge in as fast as 2.5 Hrs. Connect solar panels of up to 800W to keep DELTA Max running even when there's an outage. Compared to gas generator, the cost of gas, noisy operation, maintenance make DELTA Max a good long-term investment.
  • Monitor & Control from the EcoFlow App. Take control of your DELTA Max and quick-view stats right from your phone. Customize settings such as charging speeds and Dual Fuel Generator auto-start levels to fit your power needs.

  • Works great for CPAP
Style: Power Station
In testing this I was able to get 4 nights sleep using my CPAP, that’s with the tank & hose heater going. Very easy to set up (almost nothing) and use. The app is great and everything can be done from it or on the machines screen.

  • Powers my Garage/Tool Shed
Style: Power Station
So I used to have a 75 ft extension cord running out to my tool shed that plugged into a 20 amp generator inlet. I didn't want to deal with trenching and running a line so I figured I would experiment going off grid with this product and some solar panels. I will list the good and bad below with each issue I ran into Charging the generator: I used 4x200 watt solar panels on the roof and ran them to the machine. One the best day so far I have gotten about 475 watts input on the solar panels and have two facing east and two facing west since I am looking for the longest input not the highest. It charges just fine without any issue. At dusk I can hear a relay clicking which I looked up and other users have reported it is the solar generator recognizing some minor input by the solar panels but not enough to click over the charging aspect. I hope there is no long term issues with the relay App: The app is amazing and I love it. The garage gets very mild wifi but the generator is able to pick up on it. Set up is a breeze and I can control the outlets, run time, charge capacity etc from the app. It is very convenient. Power: The power is absolutely amazing. I have my garage hooked up with 6 Shop LED lights drawing about 300 watts and a fan on a seperate 15 amp circuit and a sump pump that is crucial for the drainage in the backyard + and any power tool you can imagine on a dedicated 20 amp circuit. The 20 amp I have a true HD 20 amp plug running into the inlet. I have turned on the lights, sump pump and air compressor all at once and this had no issue powering everything with zero start up lag. I turned the sump pump off and powered up the shop vac and measured the watts and was close to 1800 with the vac and compressor on. I am absolutely impressed with the power this thing can deliver and was super worried about it running these things however it shows no issue. I have faith it will power the table saw and miter saw without issue as both those machines draw a lower wattage and amps than what I experimented with. Run Time and Measurement issues: This is my biggest concern with this machine is I don't feel the battery capacity is a true 2kwh design. I have a "kill a watt" measurement tool and it is measuring my sump pump at 680 watts however this is measuring the same pump at almost 800 watts. That is a huge discrepancy and it seems like there is a markup of watts in anything it is running. For example my bug zapper on the kill a watt measures at approximately 60 watts but on the generator it is pulling 78 watts. It is almost like anything drawing current is marked up by almost 15-20%. Another major issue I have is the machines draw on itself while just sitting there. My shed has a constant draw of around 5 watts (measured with the kill a watt machine) when everything is off. This should mean that with nothing running I should still get roughly 16 days off the machine with nothing running. That isn't the case as it will run itself down in about 2.5 days without anything powered on. That means the generator itself is drawing a considerable amount of power just to keep itself on whether that is to keep it connected to wifi or keep the fan going etc. Not sure why but that just feels unnaceptable to me. I will go to bed and it will be at 100% and I will wake up and it will be at roughly 82%. That makes it really tough to be reliable in the winter when I am not getting a huge solar input. I am worried that it won't be able to keep up with the draw let alone power the sump pump and anything else needed during that time frame. I could get another battery to supplement this but you are limited to 800 watt solar input and to charge almost 4kwh isn't going to happen on the best day in the winter where I live. That is a huge cautionary tale for anyone looking at this for off grid. Edit #2: So I am halfway through winter and found two things out. I can extend the standby by turning off the power to the outlets and just keeping power to the USB chargers. This gives me roughly 10 days in standby mode and I can still log onto the unit and see what the power is and it still connects to wifi. Only problem is it does not charge below 40 degrees Fahrenheit. So for the most part it will be sunny and will not charge if it is under a certain temperature. ... show more

  • Great Product!
Style: Power Station
I watched many YouTube videos before deciding to buy this thing. Truthfully, there was another generator I was considering, but they haven't been able to make their commitments and people are waiting more than a year for those. This was in stock and ready to go. It arrived with 30% battery life, so plugged it in and changed it. It has two options for charging with 110v - Fast and Slow. I chose Slow. The fans kicked in and it charged in about 2 hrs (really didn't pay close attention). Once charged up, time to test: First up, my 7 cu. ft. freezer with all my beef (more precious than gold!). Hooked this baby up, and checked it every hour or so. I only let it stay on battery for about 8 hrs., but looks like it could probably make it at least 36 hrs. or more. That's good for me! Next, was my refrigerator. This is a side by side, and it's not huge or anything, but it's a new Whirlpool one. Plugged in the Ecoflow, and let this go for 6 hrs. I estimated that after 24 hrs. it would have had 20% battery. That's good. This will fit my needs. This will also connect to two other of their external batteries to increase capacity. Overall, this is well worth the money to me and gives me some peace of mind if power does go out. And no, I haven't tested solar on it... yet! ***UPDATE 4/24/22*** Lost power to my house. Plugged my freezer and refrigerator into the unit, but it showed a "!" and the charging "circle" was flashing. It showed I had 0% battery and less than an hour of power available! Both the frig and the freezer kept running - even with the error shown. Power was restored to my house about an hour later. Plugged the unit into the wall outlet it was previously in - and the error was still there and didn't show that it was charging the battery. Sent support and email (Saturday), not expecting much, but received an email back! Their customer service is responsive. Today, I powered on the unit and it's showing 100% again. Will let you know what happens. ... show more
