We recently purchased the EcoFlow DELTA Pro and an extra smart battery to expand our power available. There was a terrible thunderstorm this past week that knocked out our power for several hours. If we didn't have the EcoFlow DELTA Pro and the extra smart battery, we would've been without power and no way to keep lights on, fridge/freezer running, and more importantly keep cool with our window unit plugged in. Thank you for making such an easy to use product! We will definitely be expanding further in the future!

The Delta Pro is everything they said it would be and then some. We Took it camping. It was Awesome . Everyone was amazed how it powered everything & kept our electronics charged all weekend. We Love this brand and their products. I ordered the smart generator just in case. Can’t wait to try it out. Thanks EcoFlow Keep up the Great work! J

We bought 2 ecoflow delta pro units and 2 additional batteries to use in our garage in the event of an outage. They are charged using the ecoflow panel system to keep the batteries topped off. We have been pleased with the quality of materials and feel this is a good solution to keep our fridges powered in the event of an outage.

I love this generator! I currently use it as my QUIET indoor generator when power issues arise. Also great to take on trips or for outdoor camping. I couple up the 220 Watt bi-facial solar panels and I am never without power. This thing is a beast and I also have the Delta mini for super portability or smaller jobs. Great customer service with phones answered very quickly and very different than all those reviews that knocked the customer support. I give them an A+ for customer support. Don’t wait because these solar generators were not available at the end of 2021!!

We lose power all the time and I needed a backup system for those moments we lose power from a few seconds to a few hours and maybe help with offsetting my monthly bill. After the last hurricane and being without power for over a week and having to refill my generator every 11-12 hours I needed to find another way. I looked into many name brands, found out my insurance would drop me if I put solar panels on our roof so I needed to come up with another plan. I didn't need a full system, or have a system where the local electrical company could remotely turn off my system, but needed a system in the middle that could also be portable. So I found this things called solar generators and started looking into them, all the companies have there own +/- and EcoFlow was the winner for all the things I needed. From the install 3 months ago we have lost power 2 times, ones for almost 2 minutes and other for around 3 1/2 hours. My wife and I didnt even know we had lose power until we had a phone call asking if we had. My answer, no idea maybe, let me check my APP. I finished phase 1 3 months ago with a Home Control Panel, 1 Delta Pro 3.6 and 4 solar panels and a double pull switch that makes it super easy for my wife to change to generator power to charge the Delta Pro when am on the road if needed. The design below is my personal design that gives me backup for backup. I can recharge my Delta Pro via of: - Grid - Solar - Generator AMAZING product and I look forward to getting 1 more Delta Pro 3.6 and 2 Delta Pro extra batteries within the year with 4 more solar panels. The only Con I see is, if a main Delta Pro goes out for whatever reason and you have 2 extra batteries your dead in the water. So you're better off getting 2 Delta Pros 3.6 per leg for the Control Panel and adding what you need from there so if your main units dies you can use the extra battery on the other leg giving you house power. Highly recommended

I was one of the first DELTA PRO owners receiving this unit when it was first released. It provides plenty of power to keep me going in case of power outages. It’s powerful enough to keep my refrigerator running to preserve my food and keep my essentials running like my internet/TV and lights going. I have several solar generators and I have found that the EcoFlows are the best. I love the app that allows me to see all of my EcoFlow devices. I am set for the next decade!

I purchased this to replace the fossil fuel generator I use for my fifth wheel. Finally had a chance to use it this weekend for a trip to Yellowstone area during Memorial Day weekend. It worked wonderfully. First night used it just to run lights and TV by plugging in via 110 adapter while stopped at a truck stop for the night. Next night plugged into 30amp and was able to run one A/C, lights and TV. Did not try microwave and A/C at the same time but I will be running more test once I am back to the house.

After a few wildfire prompted power cuts and hassles with gas generators, I started looking for a battery-based unit to keep the essentials going without the gas smell, noise, and carbon monoxide risk. There seemed to be so many new options, but the EcoFlow Delta Pro really stood out. It is amazing how much they fit into this thing, not to mention the battery capacity and power output. The 400W solar panels are also really impressive — a bit heavy to carry around, but perfect for us to have ready here at home. Now I find myself secretly waiting for another power cut so that I can connect up the EcoFlow!

I purchased this for a backup, emergency scenario for my house. Within 2 weeks of getting it, we lost power about an hour before sunset I easily plugged in a light, and made plans for the fans and freezer I would soon need to power. Luckily, the power was only out a couple hours. However, my initial feeling when it went out was one of “I got this “ rather than the usual dread I had felt in the past.

This has really upped our boondocking game. We have the EcoFlow River Max, which gives us about a day of power for our camper van, running a sink water pump, mini-fridge, lights, and a pot or two of coffee. We just returned from our first camping trip with the Delta Pro and it allowed us to do everything we did with the River Max and more for nearly a week on a single charge. The main appeal of the Delta Pro is the ability to power larger AC appliances. We now have a microwave, 5000Btu AC unit, and are considering an induction cooktop for our camper van. We have not done a full drawdown test on the AC loads yet, but I expect 6-7 hours of run time out of the Air Conditioner...maybe more if I cycle it. With the larger draw items, we will need to recharge the Delta Pro on the go, which is the one area that could use some improvement. When charging from a car outlet (12v) the Delta Pro seems to be pulling more amps than it should, and blows fuses (on the car). We had the same issue with the River Max, and EcoFlow was awesome about releasing firmware updates that fixed the charging problem. I like how the app allows you to select the charging current from 4, 6, or 8 amps to limit the draw on thinner vehicle wiring. In our case, the Delta Pro will not charge above 4 amps from a 12v source, or it will blow a fuse (15 amp fuses). I believe the issue is that the charge (4amps x 12v = 50w) PLUS whatever DC load is being drawn from the Delta Pro (lights, fridge, fan) are all coming through the charging cable. So if I have 50w of charge coming in, and 150w of load, it appears that 200w is coming through the DC charge cable, when it should only be 50w. I'm really not dunking on EcoFlow about this, since we had the same problem when the River was new and their firmware updates fixed it. Really though, charging this from 12v is silly. There are so many better and faster ways to charge this, and wow is it fast from an AC source!
