I got the EcoFlow DELTA 2 plus Extra Battery (1024kWh) primarily as a backup for critical home appliances (e.g., refrigerator, freezer, possibly furnace) in case of power failure. I had joined the Facebook group EcoFlow DELTA Series Official Group to learn as much as possible from current users. I’ve found this group great for providing information, especially when it comes from EcoFlow technical staff. There’s no doubt the DELTA 2 would serve its intended home purpose, but due to its relatively light weight and reasonable size I’m now considering its use during camping trips to power an induction stove, water kettle, Instant Pot, electric blanket, and electric heater. I’ve experimented at home and these all work great, though use a significant fraction of the available capacity, even including the Extra Battery. I’ve acquired a couple of 200-watt solar panels to replenish the power used, and will determine soon if this is a viable approach. The ability to very quickly charge when AC power is available is great, as is quick solar panel charging given sufficient panel power. Biggest drawback is that the DC5521 12V outputs are limited to 3A as my camping system is designed around having a 12V battery with at least ten times that amperage. Oh, and that cable connecting the Extra Battery needs 90 degree connectors so the cable doesn’t stick out 7”.

I am a fan of EcoFlow and their products! I enjoyed my River 2 pro and 220 NextGen Solar Panel so much I ordered the River 2 and 110 watt solar panel strictly for it being so portable and lightweight! This panel is well designed, easy to move around and set up in no time! I love that the case is the kickstand as well as a place for protecting the panel when not in use. It has enough room for the solar to xt60 cables too! The panel produces 91-105 watts regularly! I am so happy with this purchase. I recommend this panel and the EcoFlow brand for sure!

We did the research, over and over, and the EcoFlow Delta 2 came out on top, over and over. So we just plunged and bought it. Love the type of battery it has!. Love the way it looks, love it's longevity, love that it MAKES NO GENERATOR NOISE, love that it is so expandable! We will take it camping, but we are also now strategizing how to set our house up with a stack and solar for alternate energy. Our power goes out often here and how nice it would/will be to have this slick alternative all set up to go!

Just recently purchased this, and I'm very happy with it. It is mostly just for a backup for an outage, but fills the need of charging everyone's devices in the meantime. It was also one of only a couple devices that had LiFePo4 chemistry, so I won't need to be concerned about it performing well in many years to come.

Received my Delta 2 a couple days ago as Hurricane Ian took aim at Florida. The manual was clear and easy to follow. When I turned it on, it showed 27% charged. From the wall outlet, it charged fully in less than 40 minutes. This morning, no power thanks to Ian, so I put Delta 2 to the test. First a couple of LED lights and a fan, then the most important thing to start my day .... my Keurig coffee machine. It brewed two large cups of coffee effortlessly, peaking at about 1376 watts. Yes the fan was audible for a few minutes but not nearly as intolerable as a generator. Then for the heck of it, I plugged in a 10,000 BTU 16 EER air conditioner and Delta 2 did not skip a beat to get it running. I ran the AC for about 10 minutes just to cool a bit and lower the humidity. I also ran the refrigerator a couple of times until the compressor went off. In the mean time I connected the solar panel. There wasn't much sunshine but I still got about 120-130 watts. at the end of the day, my Delta 2 sat at 89% SOC, enough to get me through the night. This little beast performed flawlessly and was so simple and intuitive to use. I will definitely be getting an additional battery and solar panel. This will be a great creature comfort to go camping or picnicking.

I’m an owner of a few EcoFlow products - started with the River Pro and then I purchased the Delta Pro. Huge difference between the two in terms of capacity and capability. The new Delta 2 bridges that gap with a powerful product in a better price range. Fan noise is normal and the waterproof case is perfect!

I just got my EcoFlow Delta 1300 (international version in South Africa). Fast charge, build quality, elegant design are top of every other competitor out there. If they can built an extension battery (not just daisy chaining units), this will be a winner. Also the MC4 to XT60 cable gauge is underrated for paralleling a second string of 3 x 110 W panels. Overall, I am satisfied with the product

I researched all the options available and made the decision to purchase the EcoFlow Delta 2 portable power station. I have not been disappointed. This device is much more than a tool for dealing with power outages. I have used it daily, even during a real-world power outage and it has performed flawlessly each time I have used it. I purchased it as a bundle with the 220-watt portable bifacial solar panels several months ago. I've only had a few really good days of sun to test the panels, but I've been really impressed with the power these solar panels have produced to date. I can't recommend these EcoFlow products more. I think the Delta 2 hits the sweet spot for most people, you just can't beat the LFP battery chemistry, great app, and the 5-year warranty. I also like the fact that you can pick up the Delta 2 without throwing your back out. You just can't beat it.

I bought this generator because of a hurricane that left us without power for 3 to 4 days. I haven't really tested it out yet but it has been used and works great. I also bought the solar power panels to charge it. I will test it out one of these days.

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!
