Style: DELTA 2
I read a lot of reviews and watched many videos before buying the Ecoflow Delta2. My main use for this Delta2 is for overnight camping trips and use as a back-up power in case of black-out conditions to run some equipment like Refrigerator and be able to heat food using the microwave. Delta2 doesn't have the battery capacity like Delta Pro but with a good solar panel it can definitely come handy when required. One can always add an additional battery that again works seamlessly to extend the battery capacity or buy the Ecoflow Smart Generator. I was debating between Bluetti EB70s and Ecofow Delta2. The reason I bought Delta 2 over Bluetti was the battery capacity. Delta 2 provides 1024WH as compared to the 716WH from the EB70s. Delta 2 met the power requirements that I was looking for. I could not find any offering by Bluetti in the range of 1000WH capacity. Delta 2 was of course more expensive than Bluetti but the surge power (also called X-BOOST by Ecoflow) is really high. So running a microwave for a short time or a coffee machine at a campsite or picnic is not an issue at all. I bought a combo pack (Delta 2 and solar panel). More about this combo later in the review. The other reason was the 5 year warranty that comes with the Ecoflow Delta2 vs 2 years for Bluetti. Some models from Bluetti do offer 4 years but were expensive for my use. Below are a few things I like about Ecoflow Delta2 after using it for sometime. 1) Construction - This is a solid built product. The bottom edges have these rubber bumpers for extra protection. The form factor is designed well to fit in the car. I hope the handles were not protruding out as they are now and were more integrated into the main box. The box is strong and one can easily put heavy items on the top without any issues. With the LFP battery and 3000 battery cycles, the Delta 2 will last forever. 2) Display - It's big and clear. Very easy to read even on a bright day. All the connections that are turned on are shown on the display even when a load is not connected but for USB only when a load is connected, the icon is displayed. Not sure why only the USB icon behaves like that. Not an issue at all but just wondering why a different behavior as compared to other connections. 3) App and Connectivity - The phone app works great and it's very easy to use. There are so many options that you can set via the app. Connecting the Delta 2 to the app was a breeze. It connects to WiFi without any issue and also to bluetooth. The app shows correct data 99.9% of the time. Once in a while you have to refresh (close/open) the app to get the latest data. It is very rare but I did notice it. When the WiFi is available, the Delta 2 connects via WiFi. If there is no WiFi connection, it automatically switches to Bluetooth connection. The connection is just seamless and you are always connected to the Delta 2. 4) Charging - Delta 2 can charge at a whopping 1200W to be ready from 0% to 100% in about just 80 minutes. The fans do kick-in to dissipate all the heat generated during this fast charging. I personally charge the unit at 500 W with fan running but much less noisier and may be better for the battery life. The solar charging can go up to 500 W. I don't have enough solar panels to check that max limit but this can be a really handy feature during a blackout conditions or with limited hours of sun during camping. One can charge the battery before leaving camping or any other work. Charge while driving from the 12V DC outlet in the car (Also known as the Cigarette lighter port) and the battery will be 100% when you reach your camp/work site. 5) Output Connections - There are more than enough connections that one can use, in my view. With a massive 1800 W peak capacity and 2700 W of surge capacity, I think you can run almost any home appliance with this Delta 2. The provided ports like USB A, USB C, Power Outlets and 12 V (Car type) are good to power any device you may have. Now coming to the combo I got. I bought the combo of Delta 2 and Solar Panels that were rigid. I was not happy with the size and format of rigid panels so I reached the Ecoflow support team. Even though I made that choice and now wanted to get portable panels, the Ecoflow team worked with me. The support team was amazing with quick responses and answering all the questions I had. It was good to see Ecoflow believes in good customer service that still cares about their customers. One of the best customer service teams I have worked with. One option that I would like Ecoflow to add will be to set the discharging and charging percentages even when connected to the power outlet. I would like to connect a solar panel for charging and connect my garage refrigerator to Delta 2 and use the battery power. If the battery falls below a certain level (let's say 30%) it can charge via the power outlet, else the refrigerator can keep running via the solar power. This option is provided when you connect a Ecoflow smart generator to Delta 2 but not when connected to a power outlet. I hope Ecoflow will implement this feature in the future software update. ... show more

    • Game changer for power outages

I was reluctant to purchase this unit due to the price. I don't often make purchases in this price range. But after being quoted 15k for a generac outdoor install, this is a far cheaper option to help deal with our power outages in California. And I also heard outdoor generators have problems as well and they have maintenance plans, etc. Nothanks. I researched all the different brands of solar/electric generators at length and decided on ecoflow, which is apparently the trendsetter other brands seem to follow as far as innovation. The next step was to decide which model. I didn't want to go too small and regret it, or have to make a second purchase later to get a more capable generator. So I settled on the Delta 2. The sale price combined with the capability was as much as I could possibly afford at the time. So I pulled the trigger. When it arrived, it was smaller than I thought, but that's a good thing. I immediately plugged it in and it took off charging at over 1500 watts! Ecoflow has a patented XTREAM charge system on their new units. The fans turned on and it finished in less than an hour from 35% Under heavier loads or fast charging the fans will come on. Seems like there's a quiet background computer fan sound, and a more serious load speed which is a little louder but expected and acceptable. Each output "section" has an on/off switch. If you have devices like phones or tablets on USB C, or regular USB plugged in, they will not charge until you turn on the on off switch for the front panel device outputs. Just a simple button press and a light which confirms. The devices light up and charge. This can also be done on the accompanying app. Turn off the section when not needed to help conserve battery. Same with the 6 110 plugs on the back for your household devices. There is an on/off button for that section as well. The readout on the front panel is bright and clear. And shows time remaining until charging is complete, then alternates to time remaining when outputting power. I charge the ecoflow during off peak hours when electricity is cheaper. Then during the day, I usually unplug the unit from the wall and run my entertainment center with it. During the daytime. My power consumption for a 55" tv, a sound bar, and an Amazon fire stick is usually 79 watts. The display shows you in real time what you're load is. And constantly calculated time remaining. I cannot run the cable box from the ecoflow because when I unplug it, it takes 30 milliseconds to convert to battery power. That is too long for the cable box and it restarts, Interrupting DVR recording and making my wife mad. So I have that on a smaller UPS(Uniterruptable power supply) backup with 0ms switchover speed for sensitive electronics. That's also where I plug 2 routers because we have a critical work from home employee who needs a redundant connection to Xfinity and also a backup 5g T-Mobile router. The app that is available on your phone to control the ecoflow works well. It does have updates and firmware updates. Functionality is added. It connects via Wi-Fi and Bluetooth, both incorporated into the ecoflow unit. Also another aspect I like is the simple addition of solar power. Not just with the overpriced folding panels ecoflow sells. I didn't buy those. I used a $68 100 watt panel from Amazon and it plugs right in and works fine. No muss no fuss. HELPFUL TIP- the ecoflow DOES NOT SHIP WITH THE SOLAR PLUG. Only if you buy the solar panels is it included. You CAN order the plug from ecoflow but it took over 2 weeks to receive. And ecoflow uses the SHOP app to track their shipments with DHL. Don't recommend at all. Way too slow. Buy a generic adapter with the corresponding yellow plug on one end and the 2 solar connectors on the other from Amazon. Way faster. Also avoid eBay for solar supplies. I ordered extension cables and they ended getting lost from China and they took 3 weeks to arrive. Again, Amazon carries them. Go there. When you have the cabling, you just click the positive and negative cables into each other and you're done. Mounts your panel somewhere. I just put mine on a fence. No azimuth, no elevation coordinates. Just flat on a fence. I get about 85 watts peak flow. Usually max output on any 100 watt panel is 90. And that's calculating angles and making or buying the mounts. Do as you see fit. This ecoflow delta 2 will take 500 watts solar charge and so I will probably add 4 more 100 watt panels. You can buy one 500 watt panel, but they're expensive and physically bigger. After you have solar connected, it shows you're input wattage real time. And automatically uses it to charge even when using your appliances. My goal is to provide 500 watts input and disconnect the unit from the wall entirely, running my entertainment 'off grid'. Another mention is the ecoflow store online. When you buy a unit, it gives you 'ecocoins' for completing your online profile and registration of your unit. I immediately earned enough coins to get $10 off the purchase of the solar adapter from ecoflow. But that's when I found out it was a week before they even bothered shipping it. Just stick to Amazon. Bottom line I like the unit. It's another source of real power during an outage. It's not as big a step as installing a generac but the larger exoflows have optional home power integration features which are interesting. And they sell extra 'batteries' for the units which are nearly the same price but lack the screen and features of a main unit. Might as well just buy another main unit for the extra $100. At this point I would consider a sizeable ecoflow home backup system before a Tesla Powerball or a generac. Unit is made in China. ... show more
