Style: DELTA Pro+400W Solar Panel
I have to deal with hurricanes in Florida, along with frequent power outages. I bought this because I work from home, and having no power is not an option (before the EcoFlow, I have used various batteries, and a Ninja solar battery). The EcoFlow will be used inside, not outside. I'm currently running multiple tests (I'll post updates as I get them). So far, everything is working within specifications. As others have stated, it's heavy. You won't be carrying it around with you during a hike. The phone app is very cool (lots of config options). I noticed the available battery power is always changing, because the watts in-use fluctuates. It does make determining how long the battery will actually last...impossible. You'll have to run your own tests on the devices you want powered (especially for a disaster scenario). It has low noise (but not zero). Has a nice, bright digital panel, which you can adjust the brightness and standby time for. The 2 available battery expansion ports are awesome; perhaps a future purchase. I did email the company about a question I had, and got an immediate response. So, that's good. First impression is, I like it. Is it worth $5,200? I think in a disaster scenario, yes (I know what it's like to have no power for 5 days). If you're using it to power tools at a worksite, probably not. A generator would be cheaper, and fine for outdoor use. UPDATES more to come... -MrNetTek

This is a revised review. In my original review, I spoke about how heavy this unit is, that is very true. At approximately 100 pounds, this is something I don’t want to be picking up off the ground to move very often. What I neglected to mention it is on a set of wheels and the handle pulls out a good distance for moving it where you need it. They have other models that depending on your needs, you might be able to purchase that don’t weigh as much and still meet your needs. We have a Honda generator and it is the 2200i. Since we have sensitive electronics, having an inverter generator is important. Unfortunately, we didn’t buy a big enough one for other important things like major appliances, such as refrigerator and freezer. Since gas prices are through the roof, we decided to get the Eco Flow Delta Pro since everything we read said it could run big items. We have had it for three days now and it took all day to charge the batteries. Yesterday we finally tested it on our refrigerator and it worked fine. We started with the batteries fully charged and it came up with 20 hours of run time. This will save us from having to run to only one store that carries dry ice that is close to us without the worry of losing a lot of food and things like milk that need to stay cold. I still need to test the charging with the 400-watt solar panel, but I expect that to work. Now it is hoping that we don’t lose electricity, but we usually do at least a couple of times a year. I feel that we will be ready if we do lose electricity. The only down side to these solar generators is they don’t seem to make an inverter model. Make sure you use surge protectors on what you plug into this unit just in case. With my test to make sure the unit worked was with one device. We will be attaching other items during a power outage which will reduce the run time. I still have not tried to charge the unit with the 400-watt solar panel, but will update my review as to my results when I do.

Genuine product. 3.6KWh is misleading. It shuts itself off when it gets to 25% capacity. Realistically you only get 2.7KWh of use.

Bought the EcoFlow Delta Pro & 400W Solar Panel bundle to use for power outages and backing up two refrigerators, and it's working great. With it's pass-thru & fail-over feature, you can leave devices/appliances plugged in all the time, and it will switch over to the battery power automatically & quickly anytime the power goes out. No more worrying about food spoilage during a power outage, and it's cheaper than whole-home battery backup systems. The EcoFlow smartphone app has many useful features and lets you monitor & control the device remotely. The solar panels work well too to recharge the Delta Pro. The only real downsides are that both the Delta Pro and the 400W solar panels are heavy, so portability can be limited, the angle of the solar panels cannot be adjusted easily with the case that acts as a stand, and the included carabiners used to mount the solar panels to the case stand don't hold up well, but EcoFlow support has been great by quickly sending me a whole new set of carabiners.

After much searching for a solar generator, I believe I made my best decision. Sure enough I still hold onto my belief. I considered the unit itself and the reviews and other factors to include price at the time. A very powerful and quiet unit. I am impressed. I recently bought this Solar Generator and so far it is proving itself. I am a lover of Ecoflow products!
