Style: DELTA Pro 3
The EF ECOFLOW DELTA Pro 3 is basically a robot genie for electricity. 4096Wh of LFP battery power (expandable to 48kWh!) means I can run my fridge, lights, and probably a small spaceship without blinking. Setup is easy, output is rock-solid, and solar charging works like magic. It’s heavy, yes, but that just makes it feel important — like I’m holding a tiny nuclear reactor in a very friendly way. Perfect for camping, power outages, or showing off to neighbors. Five stars. My electricity fears have officially retired. ⚡🏕️

Style: DELTA Pro 3
The echoflow Delta Pro 3 is a well engineered and attractive product that allows you to have 120/240 volt AC split phase power from lithium batteries. Anker makes a good competitive product that sells in the same price range as the Echoflow Delta Pro 3. Before you buy the Echoflow you do a product search by looking at the available selection of Lithium battery devices on Amazon. Then you should look at YouTube to see people's comments on those products. You also need to be aware of the advantages and disadvantages of using Lithium batteries as opposed to other types of batteries. That is quite a bit of research work that you should do if you want to get the best product for your needs. I chose the Ecoflow because it is an established manufacturer, has a good track record, and has the specific features that I need. 1) I have a couple of gas generators that provide adequate power but they use an alarming amount of gasoline. I can quickly recharge my Echoflow using the (provided) 120 volt AC power cord that plugs into the Echoflow. The 7000 watt generator handles that load with ease and can simultaneously run the rest of the house's power needs. I can run the gas generator for a couple of hours per day and fully recharge the Echoflow. Running the generator for this limited time period is really quite fuel efficient. 2) The Echoflow has a 30amp self locking outlet which is the same as on my gas generator. I remove the power cord from the gas generator and plug it into the Echoflow and am able to operate the house using the Echoflow for the remainder of the day. I can even run my 240VAC well pump! 3) I can extend the runtime of the Echoflow by plugging in a few portable solar panels. more runtime in the future I can double my battery storage by buying another battery pack. If I want to double my maximum wattage I can buy another Delta Pro 3 and use a cross connect kit so I wind up with needing a 50 amp plug & cable rather than a 30 amp cable. A recent one day power outage showed me that this whole system works quite well and I don't expect that I will need to buy an additional battery or an additional Delta Pro 3 unit. Finally, I should mention a few problems: 1) The on-line user manual needs to provide much more detail about the unit. 2) The various plugs and switches need to be labeled right there on the machine. 3) Right below the AC power input cord there is a slide switch. As you face the rear of the unit moving the switch to the left causes the AC outlet to charge at its maximum rate of about 1800 watts. This is great if you have a 20 amp 120 volt outlet. If you are plugging into a small generator or a 15amp house outlet you need to slide the switch to the right (in the manual this is called the "adjust" position.) You also need to use the cell phone app so you can adjust the maximum charge rate. 4) The cell phone app is exceedingly useful and you should not buy this Echoflow unit unless you are willing to download the app to your cell phone. 5) Lithium-ion battery devices all suffer from have a quite limited temperature operating range. The ideal operating temperature is between about 40 degrees F. and 88 degrees F. The unit should never be exposed to less than 30 degrees F. or more than 115 degrees F. 6) The manual cautions you to never allow the unit to get wet. All that being said, I found that the Delta Pro 3 is an excellent match for my needs.

Style: DELTA Pro 3 Extra Battery
I bought this extra battery because I already had the Delta Pro 3 and I live in a place where the power grid treats “reliability” like it’s an optional upgrade. I figured, why stop at 4kWh when I can go full supervillain lair and stack another 4kWh on top? So I did. Now I’m sitting at 8,000Wh of pure, unadulterated “I laugh at blackouts” energy. This thing is stupidly good. Charges fast, runs quiet, powers literally everything I throw at it without breaking a sweat. Fridge? Check. AC unit? Check. Wife’s entire skincare fridge that somehow uses more electricity than the actual refrigerator? Also check. I ran the house for three days during a storm and the only thing that died was my excuse to skip doing the dishes (“Sorry honey, no power”). The expansion is seamless—clicks in like it was born to be there. The app actually works (unlike certain streaming services I could name), and the build quality feels like it could survive being dropped off a truck driven by someone who failed driver’s ed. Only complaint: it’s heavy. Like, “I now have a new core workout called ‘moving the EcoFlow’” heavy. But honestly? Worth it. I’d rather deadlift freedom than beg the electric company for mercy. If you’re on the fence, just get it. Your future self—the one sipping cold beer while the neighbors argue over who gets the last extension cord—will thank you. 10/10. Would survive the apocalypse again.
