    • Keeping the RV Cool and Bright
Style: DELTA Pro+Extra Battery
I use these items to power my RV when I don't have land power. They run my 13.5K A/C and, without solar panels connected, will last between 4 to 8 hours depending on how much the A/C has to work. Separately, it also powers the microwave, and without the A/C or microwave, will power everything else in the RV. The power station and extra battery are sync'd and discharge and charge as a unit including pulling solar power from my panels. I've tried them with two linked 100W panels and, separately, with a single 400W panel and, with a bit of adjustment during the day, the captured energy is impressive. I did notice the Ecoflow didn't like a Progressive power management unit plugged in between the RV and the power station's 30amp outlet. I'm very satisfied. I have several other Ecoflow units and I'm happy with them all. ... show more

    • Gives me peace of mind.
Style: DELTA Pro+Extra Battery
I love these! I have them set up with two others I bought last year to power my whole home in case of a power outage. They charge relatively quickly out of the box and automatically keep the level at 100% so they are ready when needed. I tested them and, based on my usage, they would last 6 or more days according to the readout. I had lights, refrigerator, a room AC, TV, and phone chargers all connected. With optional adaptor, I can just plug them in to the power plug previously set up for a gas generator. I will update this if I have to actually put them to the test, but right now they give us peace of mind. ... show more

    • Looks great, but doesnt work out of the box.
Style: DELTA Pro+Extra Battery
The item looked great in the ads, and on paper. After I recieved these, I waited until the weekend to unbox and try out. The units are much heavier than they look. I opened them from the bottom, folded the flaps back and pulled the box straight off. Plugged them in, and the unit continues to cycle on and off. It wont charge, or power anything. I called and emailed support, and got 2 responses asking me to reset the unit. I did, to no avail. I informed them of the failure, but have heard nothing since. Amazxon circles back to ecoflows support, so I am, for the time being, stuck with a $3000.00 dollar paperweight. If anything changes, I will revamp my review. ... show more

    • Very happy with the PRO
Style: DELTA Pro+Extra Battery
Review Image by Axel W.
Purchased the PRO and extra battery as a bundle about a year ago. With the current power outage due to the SoCal wildfire, I am happy that I went with Ecoflow. Both units are currently being charged with 10x160W solar panels, which give me a peak 1.29 kw charge during the day, charging both units to full capacity. At night, I can run my most important appliances until the next morning, when the solar charging cycle begins again. I live in a camper full-time on a campground, and while other folks around me run their noisy gas generators, Ecoflow is doing it's thing beautifully and quietly. I travel a lot, so the app is perfect for me to monitor the unit's condition from afar. Very pleased with product and customer service. Thank you, ECOFLOW. ... show more

    • They are very helpful in lowering a little of my power bill.
Style: DELTA Pro+Extra Battery
So far so good! I Use these to supplement my power usage a few days a month.I plug in my refrigerator for like 3 days in a row.Then I recharge the battery afterwards. The one thing I did notice that they had a good price drop After we bought these.And their price fluctuations are very interesting. They are heavy I must admit. ... show more

    • Finally pulled the trigger!
Style: DELTA Pro+Extra Battery
Watched for the ECOFLOWs to go on sale and they did! I saved $1700 on the package deal! Living in Florida, I wanted a back-up power that does not need gas. The units are heavier than I expected, use the wheels as much as possible to move them around! I also, bought the 400w solar panels, they were on sale, 31% off! Now, I have to wait again for another panel, the price went back up. My intention is to have them hot wired into the breaker box. I already purchased a 30amp box, here on Amazon, will have that installed, at least I can place that inside the house. No noise that alerts others you have power. I did my research on solar generators and ECOFLOW kept coming out on top. I am sure there are some of you out there, City Prepping was a great source. Kris did all the testing I needed to see. In the end, Amazon had the best price plus offered the warranty coverage, no brainer. Hope this helps! ... show more
