Style: DELTA Pro
This item is great to have in the house. Compared to a gas generator that could cause someone to get sick they always has to stay outside. The original cost is high. better to get it on a lower price well worth it it is very heavy heavy but it does have a handle at the bottom. Alot of hook ups on front side a d back. And you can charge it up in a house current. Last full charge for 15 days. Excellent item to have and you can. My two to hook up together for twice the a.ount of days and buy solor panels to use with it

Style: DELTA Pro
I’m very impressed with the EF ECOFLOW Delta Pro. The 3600Wh capacity is more than enough to power my essential devices during outages, and it’s also perfect for camping trips. The fast charging is a game changer—it goes from nearly empty to full in just a few hours. I love the multiple AC outlets and USB ports, which make it easy to connect all my devices at once. It’s a bit heavy, but the built-in wheels and handle make moving it around much easier. Overall, it’s a reliable and powerful portable power station that’s worth the investment.

Style: DELTA Pro
Hands down, the best out there. I've had this electric generator for 5 months now and have wheeled it to camping and star gazing. What a fantastic device. I can power 3 mosquito traps, 3 telescopes, a electric water pot for coco and still have capacity for music or charging phones. The app is a 8/10 and my only complaint is that nothing allows you to trend input/output so you can't keep an eye on your metrics. 100% support this product, will buy again.

Style: DELTA Pro+400W Solar Panel
The first Delta Pro generator that I received didn't power any of the devices that I tried in any of the plugs, even when fully charged. Plus, the screen only came on for 1-2 secs and then it shut off. I called them twice. The first call I was told to update the firmware. I tried that, but the app said it could not connect to the unit. On the second call to them, I was told that even if the firmware was not up to date, it would not cause the generator to not power any devices. She said we have a defective unit and that they would replace it. I was told to pack up the unit, and that a return shipping label would be sent to us. I repacked, taped up, and moved this 100 lb unit to our front door. After doing all that, then I received an email saying that we needed to update the firmware and video tape everything we do and send it to them for review....and no shipping label was received. And FYI, I also had purchased the 4 year service contract. I felt like I was getting the run around even after getting the service contract. I decided to call one more time. Then, they promptly sent me a return label. They asked for a photo of the package that was ready to be shipped. Did that. Within a day of them receiving the returned unit, they sent me a new unit. This one seems to be working well.

Style: DELTA Pro+Transfer Switch
We got the Ecoflow Delta Pro with transfer switch to run our furnace, fridge/freezers, sump pump and basement sink pump (where furnace condensate pump drains) overnight when the power is out due to storms. We had an electrician install the transfer switch not too long after receiving the unit. While we have not had an outage since we got it (not that I mind!), we have tested it out and it will be more than enough to allow us to peacefully sleep overnight. Except in situations when the furnace is going nearly constantly, we expect that this unit will run about a day with what we have on it. Before, we had to juggle sleep times to make sure that the fridge didn’t warm up and/or the house get too cold. Plus there was having to deal with an outside generator and the power cables going into the house in the cold and dark to boot. We used to use space heaters, which don’t quite do enough for the northern US in the winter, especially if you are out for a few days. The transfer switch is invaluable as we also can use it to plug in the generators to run the circuits attached (the furnace!!!) while recharging the Delta pro. A few things to note: 1) The Delta Pro’s instructions recommend a 45 day power discharge-charge cycle to help maintain the battery. We’ve just added it to our home maintenance routine and use the transfer switch for the discharge part of the power cycle. It works great and also gives us an idea how long it will work when we need it. I’m actually running a testing cycle as I’m writing a review in on a cold, snowy day. I don’t think that I could be more pleased with this setup (working as planned)! 2) We have done nothing with the bluetooth/wifi interface. We’re just using it as a backup battery that we manually connect to the transfer switch and it has been doing that so far out of the box without modifying the settings. If that’s important to you, I think other reviewers commented on that. 3) The transfer switch when we got the kit is a manual transfer switch that has 6 circuits with 120v as it comes with a single Delta Pro. You operate it fully manually, and that’s what we wanted. It is NOT a standby that kicks on if the power goes out (I think that you would need a smart panel for that). If you need 240v (for central AC?), keep that in mind as you may want a different transfer switch and should get the Delta Pro 3 or two Delta Pros with the double voltage hub. Any electrician should be able to get an appropriate transfer switch locally if you need to go that route.
