Just received my EcoFlow DELTA 2. Only used a few times so far. I like everything, everything is as indicated in the description. Can definitely recommend! Very convenient device! I am glad that it really meets all the declared characteristics. And also - it is not heard at all! Works very, very quietly.

Awesome portable power station and app

Recently purchased the Delta 2 and extra battery. Was interested in the newer battery type: LFP
I have a had a pretty decent experience with using this, especially after coming from GoalZero Yeti 1000, where it was slow in recharging, pretty heavy, and no app.

One of the selling points of the Ecoflow products was the ability to fast charge via AC or solar. Via AC plug it took roughly 4-5hours to charge up both the Delta 2 and extra battery from 0% to 100% at 4-500W. Recharging from solar was also relatively easy and went from 85% to 100% in a couple of hours with a 120W panel on a sunny day. Overall, very impressed with the product as a whole. The app is also useful in looking at the battery stats and turning on/off certain ports (AC/USB/12V DC/etc) and looking at remaining time or recharge times.
I did experience an issue where I left it charged to 100% and over the course of a week, it kept dropping 1-2%, but reading through the owners FB page helped in guiding me to perform a BMS reset (discharge to 0% and slow charge back up). After doing this, I no longer see any drops.

My only wish is that it would have been great to have the extra battery function on its own. Other than that, I have an upcoming camping trip, so we’ll see how it fares.

Great Refrigerator Saver or Home Office Backup!

I bought the Delta 2 primarily as a backup power source for my refrigerator during any short power outages this winter. I can also use it as a backup power supply for my home office or a small freezer if needed.
As a test, I hooked up a laptop with additional 21" and 32" monitors while working today. I also periodically ran a 15-watt lamp, a second desktop computer, and charged some devices. The Delta 2 provided exactly 10 hours of power. According to the Kill-A-Watt P3 power meter it was approximately 780 watt hours out of the listed 1024 for an overall efficiency of 76.2%. To be honest I was hoping for more, but I do plan on picking up the extra battery. However, the basic amount should be enough to get the refrigerator and maybe a small chest freezer through the night during a short power outage.
For solar charging I picked up two 160-watt EcoFlow panels. I set the two panels up on my back porch and tracked the sun from mid-morning to mid-afternoon. The two panels generated a maximum of 250 watts of input with clear skies but noticeable wildfire smoke. I was able to bring the battery up from 30% to 80% before the trees blocked out the sun. Solar panel efficiency dropped off quickly with any shading.
I experimented with parallel and series wiring as shown in the manual. I found I got a little more wattage out of the series method. When I looked at the specs I think that was because in parallel I was exceeding the 15 watt maximum input and it was throttled down by the control system. Adding a third panel would max out the system on volts and watts, and it might be worth considering for winter charging with fewer hours of less intense sunlight. These three panels could only be hooked up in series.
AC charging was fast! I actually tempered the charging to 800 watts maximum instead of the standard 1200 watts to reduce the amperage, but even with input reduced by one third a full charge from 0% to 100% took less than 2 hours. The fan runs the entire time the unit is charging. It is noticeable but not loud.
Overall I feel this is a great item to have on standby for short power outages. It can power small appliances and a computer for a significant amount of time when needed. Set up is fast and easy. The 160-watt solar panels are fairly lightweight and appear to be more durable than glass panels. The manual should do a better job of explaining the differences between parallel and series options (that might be a good feature for the app). The Delta 2 is manageable in size and weight and would even fit in an RV for mobile power needs.
I would recommend this to a friend!

I’ve only had the Delta 2 for almost a week now, but I’ve tested it out for days with discharge and charge without issue. Fast charged and battery-friendly rate charge were both pretty quick. Total adjustability is a great feature. App is working good with no issues between the app and product.

I have a Kia Niro plugging hybrid and I have been wanting, for a long time to put solar panels on the top of it and charge the main battery, with your products I’ve been able to set up two solar panel units that are 160 W each. And here is the magic: I can charge the Delta unit with the panels and the car main battery with the Delta unit at the same time!!!

Awesome Emergency Backup Power Source!

I received my EcoFlow Delta 2 today. (Just waiting for my solar panels to arrive that we’re shipped separately…) I charged it to full capacity by plugging it in to see just exactly what it could do. I connected a vacuum to it to see just how much of a pull it would be on the system. After 10 minutes, it still had 99% charge. I then took it with me outside to run my air compressor for another 8 minutes. It didn’t drop at all. I’m totally impressed! I’m so glad to see a good emergency product be put out on the market these days. I’m going to recommend this system to all of my friends and family! Thank for coming through on your word with such a good product for the price!
I would recommend this to a friend!

Game Changer!!

I have only had my Delta 2 about a week, but it has already been a game changer for me. It has become central to my quality of life. With 1800w of AC output in such a small and complete package I now can move more freely while maintaining my ability control my environment. I have severe food allergies and the Delta 2 allows me to take my food preparation on the road with me so that I can insure my food is allergen free and cooked to my preference. No more cold, water logged food on the go. I now have a small refrigerator, induction burner, and water pot in the trunk of my car, or in my SUV. I can pull over at the time and location of my choice and by doing so level out the nutritional intake that curbs the peaks and valleys associated with delayed meals. The Delta 2 is easy to use, has ample charging options, and is rock solid in its performance. Game changer and life changer.
I would recommend this to a friend!

Great power back up delta 2 ecoflow

This ecoflow delta I got , is portable and very convenient to use. Also do not forgot to buy solar panel which also help to gain extra free power from the sun. Any parts you need afterward you can order from company website very quickly. They are fast and efficient. I strongly recommend everyone looking into this , also because This is new generation battery you can charge faster and more time than old delta model. Again I will recommend this to my relative if they look for back up power generation device and also solar capacity.
I would recommend this to a friend!
