Just recently purchased for trip out west ie. New Mexico and Colorado. Kept our cooler going all week and it charged everything no problems. The solar panels worked well too, heavy and big though. Can't see what im typing so hope everything is spelled right . Overall good product great addition for overloading.

Hello shoppers, what we all know is that the cost not cheap. However, the buck is on you, to set your destination for what comes your way. So, on that point I can say, this generator is a Hot product for the buck and worth it and we can hope as for the future that this will last for whatever use. Have a safe journey.

My wife and I suffered greatly during the Texas freeze last Feb. Ordered the Delta Max to run our kitchen appliances and to keep us warm. The unit is portable, silent and recharges quickly which is important since we live in an apartment complex with stairs. The unit was also in stock and shipped within a couple of days. Our only issue is solar recharging from our balcony? So we decided instead to buy an extra battery instead of solar for the moment.

Product works as advertised. I thought I could power my fridge for longer than 14 hrs but it looks like I'll need more than this. The 220 W solar panel performed well but after 7 hrs of direct sun it charged the Delta max to 30%. So I'll need more panels. It's a very nice unit but not as powerful as I'd hoped.

This is my second Ecoflow. I love their generators they are very dependable. I will be purchasing another one in the future. Also their customer service is great. If you have any issues-they will get back to you in a timely fashion. They will also do everything they can to resolve the issue.

It would be nice if the instruction manual incorporated larger diagrams on features of the unit and explain all of the operating modes.. I have yet to figure out if app that controls the unit can actually turn eco flow on or off.. I intend to use it in a small airplane- remotely mounted from the pilot position..

I'm very impressed with this Solar Generator, its very easy to get started with and it charges very fast. Right now I'm just charging with the A/C wall outlet, but plan to get some solar panels in the spring before we head out to Arches National Park to camp in our RV. I really like the ECOFlow 400W foldable panel, but they are super expensive. The App on your phone is also very nice, and I can track whats going on with the EcoFlow without being next to it. I might also purchase the extra battery for this next Spring as well.

The rating of 2 kWhr is really 1.4K-1.6 kWhr for the following reason: 1. To maintain good battery life, one should not discharge the battery below 10% or charge above 80% for normal operations. This is normal Lithium Ion battery behavior but specmanship means a lot of manufacturers ignore this constraint. They should just add 20% more battery and adjust the software to avoid the corner cases of Li-Ion chemistry, but most do not. Ecoflow is no exception, unfortunately I'm also unable to set the maximum charging level automatically to 80% while using as a UPS, so I have to tediously monitor the charging level to avoid the 100% charged which the manual recommends not doing over long periods of time. There should be a built-in "extend battery life" feature to make this automatic. Humans should not be in the loop to save battery life. The UPS mode cuts out for a half cycle (30mS) which some equipment can handle and some cannot. Please figure out how to make this device a 100% useful UPS in the future. In general a primary use case of "leave it plugged in in case of a power outage" seems to be somewhat neglected in the documentation and feature set. Please elevate this to a primary feature. An Ecoflow that has self-discharged to 25% when set in the corner for 2 years unplugged is of no use in a power outage. Equally an Ecoflow that has damaged the battery because it was left plugged in for 2 years in the corner is also of no use in a power outage. There isn't an automatic way to handle both these constraints, it requires a human in the loop. Most humans, especially me, are terrible at such tasks, but computers are great at such tasks.

I have 2 delta max w/ extra batteries and 2-River pro use the big boys to operate my freezers anf the other to operate my well pump and refrigerator. The rivers keep my internet up w phone and wifi and the other charge my phones and iPads all are on solar of a dedicated array. Thanks, i wish you would make a power wall like franklin

This item was purchased to compliment my Honda 2200 generator so that if there is a power outage I can run the generator in the daytime but to keep things quiet I can run my ECO-Flow at nite. I also use it to charge our electric bicycles and battery powered lawnmowers to that these items are "OFF the GRID."
