EcoFlow's systems are wonderful to have and use
Used this after Hurricane Milton knocked out power to keep our fridge, security cameras, TV, lights and fans running. Very handy to have this much power with so much battery power stored. I will be charging them back up to 80% full this month in preparation for hurricane season and go to 100% full if a hurricane is expected near the west coast side of Florida. I appreciate that EcoFlow keeps updating the firmware with improvements and any bug fixes too.

Keeping the RV Cool and Bright
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.

Big Problem No Solution
This product has a problem. The AC voltage shuts off randomly. The support team just sends the same email over and over. Its like nobody is reading the notes. When you contact Amazon they just send you down that same rabbit hole... Looking online many people have reported this problem and ecoflow doesn't have a fix..

Finally pulled the trigger!
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!

Works without the APP
I got the PRO with extra battery. I did not want to use the app because of the risk during time of warfare: these giant lithium batteries could be used as an incendiary weapon through the app telling them to overcharge. I hate to be so cynical but it's a foreign controlled company... Now, the good news is that I am using these as uninterruptible power for my internet because I don't have a phone without internet (dead zone). I used to use APC lead-acid batteries for this purpose but they wear out too quickly and also they will not accept power from my gas generator. Initial testing confirmed that dropping power from the wall does not cause the internet to drop, nor does it cause my computer to reboot. I added two freezers, a sump pump, a gas-on demand water heater (has a circuit board) as well so that when the crummy power goes out we don't lose those things. The Ecoflow Pro is a great standby power source of standby power, and it's fantastic that it will accept power from the gas generator for those longer outages. The only downside is the price!

Great Product
We recently bought this. Right after, we had a storm blow through and knock out power for 7 hours. We successfully used the main system to save meat, etc. in our freezer and fridge, charged phones and had lights. The system pays it back by not losing the food, etc.! So worth the money! Charge the main and backup battery when your power is on so you're always ready for an outage. Then, you can rotate on solar if power is out for extended time.

Very happy with the PRO
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.

Second pair
This is the second pair of these EcoFlow generators I now have. Luckily we only spent 5 days without power during Helene but with all the utilities we were running I needed to recharge the first pair every 24 hours. I wanted to run a couple more items so I now can do it doing the next power outage. I like this set of the EcoFlow because I’ve used them before and trust them. I was also surprised that I had them within 5 days of my order so great job on the responsiveness to the company on my order.
