After a lot of research I purchased the Delta 2 as a backup for my farmhouse. We have power outages here every winter and I use a duel fuel generator to run my pump for water. But keeping that noisy generator running constantly is just too annoying. So I got this eco flow for quiet efficient energy when I don’t need the big generator running. I have used it through this winter and it is perfect- extremely easy to use, enough energy for my basic house needs, and chargeable by solar or from my larger generator. And when not in use, it is very simple to store and light enough for me to move easy. Thank you for this excellent introduction to solar alternatives. I look forward to expanding in this direction.

I bought the Delta 2 after a day-long power outage, sleeping without my CPAP and worrying about the food in my fridge. I did a lot of internet research and it seemed th ebest fit for me for peace of mind, as well as supporting the CPAP on camping trips. While I've not had to use it yet, I can tell you that it is fact to charge, holds the charge like a champ (no power drain over a month) and is easy to move around the house. I love the display and the many ports to draw power from. My only regret is that the app does not seem to work with my phone/wifi network. Which I don't really care about, but thought would be cool.

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.

This generator works as advertised! It charged up so quickly via AC. Decided to test is on our freezer. Plugged in freezer and it used around 20% of the power for around 3 hours of continuous use. Haven't tested the solar panel charging yet, but that's up next.

I'm so glad I bought this DELTA 2 power station for my 3-day camping trip. I wanted to be able to power the induction hot plate I already had instead of investing in a gas powered camping stove, and the DELTA 2 provided all the juice needed, plus charged my laptop and my phone for all three days, with power to spare.

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.

As you can see from the photo we LOVE it... especially the grandkids nightlight. Living in the Texas Panhandle in Winter can be a worrisome prospect. I truly trust the Delta 2 to provide necessary power should the need arises. Two weeks ago it helped to keep our second refrigerator going during a four hour power outage. And yes, we also have a solar panel. The Delta 2 has all the output plug-ins we will ever need.

I needed to get basic power for lights into a shed that had no electrical hookup available. I have tried many battery powered lights, that just didn't cut it. They would die or were just not bright enough. I decided to try a Delta 2 and 2-100 watt solar panels to recharge the battery. I was only able to mount the panels on the east slope of the roof, but it has held the charge. I am in Ohio where it gets too cold and keeps the battery from charging when it gets too cold, so we have had several days where we weren't charging because the shed was too cold. I still have not run out of power for the 100' ten light strand I hung up. This setup is an expensive fix, but it has proved itself to work even through our cold, gray Ohio winter.

Received my DELTA 2 and 220W bifacial solar panel a few days ago. Also purchased the extension cable for the solar panel (the cables included with the panel would have been everything I needed, but I wanted some additional length). The shipping process was fast (about a week) and I received good notifications on progress. Both the DELTA 2 and the solar panel appear to be good quality, and initial tests align with the expectations I had based on the product advertising. My original plan was to use the product mostly as an easier source of emergency in-home power than my gas-powered generator, but I'm now thinking of some other potential uses as well (UPS/backup for sump pump, power in the far corners of the property, an occasional picnic or camping trip, etc). I'm not sure I'll be using the phone app given the potential security risks of hooking an emergency power supply to an internet connected device. So far, I'm very happy with my decision to purchase the products.

I originally purchased this to run a diesel heater while camping, but it has done so much more. It will run this heater a solid 3 days. It is also great for running LED lights inside my tent as well as blowing up an air mattress. I was originally going to purchase a smaller unit, but I'm so glad I chose this one as it will run everything that I need and then some!
