I bought this Delta 2 solar generator in November with two 220 watt solar panels. It runs the freezer all day and evening. Even on an overcast day it charges 88 watts while the freezer uses 47. Next step is a Delta Max extra battery so it will run 24/7

I bought the the Delta2 and 220W Solar Panel combo for camping trips to power my Dometic CFX3 45 fridge. The combo worked perfectly during a 7 day camping trip. The weather was a little cold out, but this Delta2 was capable to power the fridge for 3 days which is quite impressive. The solar panels worked perfectly and I could get 218W when aligned directly to the sun. This is a great combo for anyone with extended outdoor activities. Great job EcoFlow!

I have been looking into buying a solar generator for over 3 months. The size of this generator is perfect compared to competitors. Enough power storage and enough output for all your home back up needs. Tested it out with air fryer and after using it for 15 minutes it was still at 60% charge which I consider good. Another feature that I great is the ability to expand it with second battery. It charges extremely fast from wall. The only negative is the cooling fan is pretty loud but not bad

I've been looking for awhile and found the right one for me. I ordered my EcoFlo Delta 2. I got it just in case the power went out. as soon as I got it, I plugged it in. it was fully charge on about an hour. I have Gas generator, but it's too noisy and has smelly fumes. I can't wait I to use it on camping trips. I use a CPAP and it will help out big time. I plan on getting more.

I have always wanted some kind of power station, mostly for emergencies when we lose power and maybe using in the yard for entertaining and building projects. I was watching some videos with people living off grid and noticed a lot using the EcoFlow powerstations and how good they were. I figured it was time I finally got something and went with the EcoFlow Delta 2 with a EcoFlo 220W Bifacial Portable Solar panel. I haven't used the solar panel yet but the power station has lived up to everything that I have heard about it. Charges super fast and has charged everything that has been plugged into it and gives many hours of use. So far, a great purchase. Thanks EcoFlo.

Back in fall of 2022 I bought Ecoflow Delta 2 and the second connected battery. I put them on a wire rolling cart and hooked our 28 cubic foot fridge to just the main battery. With only battery power the fridge ran for 22.4 hours. that was with us using it as usual. When I charged dead battery (actually 1%) It was charged in around an hour. With 1 hour runtime on generator it could handle fridge for a day. Thats huge leverage power for 10 plus years. I plan to also buy the PRO model when it gets updated.

I love my new Delta 2. The Delta 2 is a second generation update of the original Ecoflow Delta 1300. It's many improvements include longer lasting much safer LFP Lithium Iron Phosphate batteries, an expansion battery port, more solar input (500W) and an even faster charging time than before. They have made many noticeable improvements under the hood as well, integrating circuit boards to cut costs and keep the same weight (LFP batteries are heavier!), improving efficiency - yet the Delta 2 is less expensive than the original Delta 1300! 
I have two Delta 1300's from the original kickstarter campaign - they really revolutionized the solar generator business and set a standard all the legacy companies have since been trying to catch up with. Before Ecoflow solar generators looked not unlike modified gasoline generators - that is industrial and clunky. But the Delta 2 like the rest of the line, look much more friendly, they blend ergonomically into any home environment rather than looking out of place like they really belong in the garage. 
But the killer feature has been the fast charging. The group of 20 somethings that founded Ecoflow had worked at drone maker DJI together, and observed the biggest pain factor was how long it took to recharge batteries. And so they figured out fast flash recharging in under 2 hours, 1.6 hours on the original Delta. The new Delta 2 can flash recharge now even faster than the original, in an hour and 20 minutes, all Ecoflow solar generator charge in under 2 hours, even in an hour for some, yet there are still competitors out there that take over 10 hours plugged into the wall. 
I did observe that when the Delta 2 is cool it charges a lot faster. Checking the internal temperature with the phone app to be 96°f, it charged at near 1200 watts on the meter, slowing down a bit at 80%, eventually fully charging in exactly an hour and 20 minutes as advertised. However if you discharge it at a very high output it heats up the batteries (I did a torture test and ran it at 1200 watts flat to 0%, with a hair drier in 30 minutes.) Then you have to let it cool down before it will recharge. After a cool down rest period, the still somewhat warm Delta 2 charged at a steady 600 watts the whole way. It took a little longer at 2 hours, but no complaint here. 
Great improvements, nice price point, expandable, lasts longer. If you are a fan of these kind of devices - you will love your new Delta 2 too I think!


I bought the Delta 2 and 220W solar and I am impressed with the engineering and packaging of the product. I love the capacity, fast charging and the ability to use up to 1800W appliances. Not heavy and slightly smaller than I expected even after watching many you tube videos.

I bought this because of its amazingly compact size and weight. I have other power stations, even built a few, but none of them pack what the Delta 2 has. The expandability is also a feature that made me buy it. No matter where I am, at home, camping, remote work site, field party, power outage/emergency, the Delta 2 and its companion expansiion battery provide me with the power I need no matter when or where I am. I keep it next to my recliner and use it as a charging station until I need it on the go, then it easily fits in my truck/car for work and adventures. I find the Delta 2 to be an amazing power system, and also a terrific value for the price. It is always ready when I need it to provide realiable power and performance anywhere, anytime. This is a 5 star product.

A Delta 2 and battery backup were purchased Dec 2022 and installed with a manual transfer switch adjacent to my main electrical panel. This setup allowed for individual circuits within my home to be selectively powered for over 9 hours when the grid was down during the Jan '23 west coast storms. My refrigerator, microwave, internet router, lights, and forced air gas furnace remained in service thanks to the Delta2.
