    • Does the job when needed.
Style: DELTA Pro+400W Solar Panel
Super nice unit and works great. Came with a 400w solar panel but haven’t set it up yet. Would recommend it and it’s expandable

The product is awesome, I send it to Cuba and I am able to have power for most of day (20hrs).

    • This portable solar generatorcan handle up to 3,600 Watts with great options for expandability!
Style: DELTA Pro+400W Solar Panel
Overall this is a really great product. I dislike that the fan engages when you draw over 70 watts. The fan isn't loud but it isn't very silent either. I used it to power my laptop system as a test for work to set appointments. The customers complained about the background noise when the fan kicked on while I was setting appointments. The unit weighs 98 lbs. which is heavy but manageable for me to pickup. It moves around nicely on its wheel base. I plan to store the unit long term for emergency. I reallllly dislike having to charge the unit every 90 days as recommended. I love this EcoFlowDeltaPro3600 with 400W solar panel system for everything else that it can do. I love that I can power an 1800 induction cooker. I love the expandability options. For a ready to go system, it is a great price for its portability, storage, ease of use, ability to power up to 3,600Watts, and expandability. I would definitely recommend this product if you are looking for portability and all the other features. ... show more

    • This particular unit is heavy
Style: DELTA Pro+400W Solar Panel
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. ... show more

    • Love it
Style: DELTA Pro+400W Solar Panel
I like this seems to work really well. I like that. It has the Bluetooth connection to your phone and it’s super easy to charge. I have not used the solar panels yet but I like that they are there in case I need them. I did plug in a 1500 W heater and the time it said it would run it but it’s two hours that was a bit surprising to me I thought it would last longer than that but sure it’s just a factor of the size of the battery. It’s a bit heavy, but that also expected based on the size of the battery. The handle to move it around is at the very bottom and while it’s in a great position when you are rolling it it’s a little hard to get to and get out other than that. I have no complaints about this machine. I really like it. ... show more

Style: DELTA Pro+400W Solar Panel
So I originally purchased a Delta 2 with Delta 2 max extra battery and was surprised how well its held up after viewing a bunch of Reddit posts and So far has worked great out the box that I figured it was time to invest in something bigger and so far the Delta Pro also doesn’t disappoint either. Quiet and easy to setup like the Delta 2 and plan on getting two more extra batteries for the Delta Pro in the next couple of months. Solar I think I need a few more panels to get more solar because the 400 watt panel gets roughly around 220-300 watts but with my dual fuel generator and solar to charge the Delta’s it’s a no brainer during brown outs or blackouts that I can rest easy knowing th fridge n freezer along with internet and so on will be useable making it great for emergencies. ... show more
