Powerful solar generator — perfect for extended power outages
Style: DELTA 3 Max+400W Solar Panel
I bought this for my family who deal with power outages lasting more than 12 hours. It has been a game changer for them. The solar panel is powerful and works perfectly — it charges the unit efficiently throughout the day. What surprised me is that during daylight hours, the solar input actually exceeds what a refrigerator consumes, meaning you can run the fridge all day while the unit stays charged. At night it holds enough charge to keep the refrigerator running the entire night without any issues. I was worried I’d need to buy extra installation cables separately, but everything you need comes included in the package. No additional purchases necessary. Really impressed with how well it performs under demanding conditions. Highly recommend for anyone who needs reliable backup power

Very large and heavy, but a beast if you need renewable power
Style: DELTA 3 Max+400W Solar Panel
In my photo, I have two solar panels. The one on the left is the EcoFlow 400 W. The one on the right is Jackery 200 W. The Jackery is very nice and portable, but does not give me the power I need for my remote jobs while I’m camping. After I got over the initial shock of how large and heavy and awkward the Eco flow 400 W panels were, I began to appreciate it. The first time I tried to set up the kickstand, I didn’t think I would ever use this thing. But it gets easier, and there is a method. You can do it by yourself if you are capable of lifting 50 pounds. Lay the soft side down first and attach the clips to the bottom of the panel, then attach the top of the solar panel to the top of the hard backed kickstand, it works. I use this solar panel with the Delta max 3 running my laptop, cell phone, Starlink, refrigerator, portable electric pan, Keurig, coffee maker, microwave, and charge various USB items. So far it seems to keep up as long as it’s charged every day. On cloudy days, I use my gas generator to charge the battery. The Jackery is reserved only for my Cpap at night, nothing compared to the power of the Delta max 3. I highly recommend Delta max 3 if you need to be off grid for several days at a time, but you will need to buy the solar panel to regenerate for longer periods of time. Just make sure you have the room for it. It’s a beast. Happy camping.

So far very impressed
Style: DELTA 3 Max+400W Solar Panel
It charged up rather quickly plugged into the wall outlet. Powered up everything i was wanting to be sure to have running during an outage. Very easy to use. Feels very well built. Time will tell. Surprised how heavy the solar panel is. I was worried about them setting out in the wind, not anymore. Just pray FedEx don't deliver it. Got a notification it was delivered so i went out to get it and nothing there. Jumped in the car and went looking for it. It was left at an vacant house in the snow. Unreal.

Solar Power Yes please
Style: DELTA 3 Max+400W Solar Panel
This is my second Portable Power Station. I have a Delta 2 max and now bought this Delta 3 Max. I liked the Delta 2 and wanted another. The Delta 3 costless and was lighter and also came with a 400W Solar Panel just like the Delta 2 did. Also was designed a little different with new tech. It's nice and is almost just like the Delta 2 max except it only has one port for the solar panel and the Delta 2 has two ports. I can hook up both 400w panels to the Delta 2 and cut my charging time down. The Delta 3 charging port will only handle 500W, but I have never got any more then 325 out of my 400W solar panels. I do live in the Northeast so 325 is pretty good. I like'em .. the Delta's and I'd recommend them.

Helpful after a Category 5 Hurricane
Style: DELTA 3 Max+400W Solar Panel
I got this to provide power in the aftermath of Hurricane Melissa. It's heavy. Both the power station and portable solar panel. As a woman it's a lot to tote around. I've used it to bring my icemaker fridge which was without electricity for five weeks to cool. As we're still without electricity I use the 400W Solar panels to charge it. I find this charges slowly even in a fairly sunny tropical climate. From 7:30am to 11:30 am gets the power station from 20-50%. Then I use the sun to run it. Even so you probably get an added 2-5% before sunset. Charging by the AC adapter is much faster, but in a post-hurricane scenario that's pretty much non-existent. I'm not sure how durable the solar panels are as the base of the panels has shown wear and tear after just four days of use. I wish they had included a proper stand for the solar panels; using the carrying case as a makeshift stand as suggested is onerous and not sturdy. The free 45W panel is useful for charging my iPhone and USB-C lights. And is thankfully lightweight. The included Ecoflow 400W panel rarely gets to that wattage, but I have gotten 412W for a minute or so. I wished the input for the EcoFlow Delta 3 Max wasn't capped at 500W. The app is cool and great for tracking consumption. Overall it's pretty handy for use for extended power outages like a hurricane, and if you need a weightlifting workout!

Easy setup of backup power
Style: DELTA 3 Max+400W Solar Panel
This battery and the solar panel were delivered in excellent condition. Easy setup and fast charging from wall outlet. User friendly app via phone to monitor and adjust settings. Comforting to know there’s a backup right there when and if the power goes out.

Compré 2, una para mi mamá y otra para mí suegra,y se las envié para Cuba, la de mi mamá se apaga, ellas no tienen esa potencia q se dice en la descripción de Amazon porq ni siquiera pudieron ponerle los watts en su frente para saber de cuántos watts es, se le pone el refrigerador y baja muy rápido la carga, no se si es q hay q configurar, pero creo q costaron mucho dinero para q muy pronto empiecen a dar problemas, esa es mi experiencia y respeto la de los demás
